+
+The vertices are projected onto the xz-plane, so the y-values are ignored.
+
+This is a low cost function than can be used for various purposes.  Its main purpose
+is for point/line relationship testing.
+
+In all cases: A value of zero indicates that all vertices are collinear or represent the same point.
+(On the xz-plane.)
+
+When used for point/line relationship tests, AB usually represents a line against which
+the C point is to be tested.  In this case:
+
+A positive value indicates that point C is to the left of line AB, looking from A toward B.<br/>
+A negative value indicates that point C is to the right of lineAB, looking from A toward B.
+
+When used for evaluating a triangle:
+
+The absolute value of the return value is two times the area of the triangle when it is
+projected onto the xz-plane.
+
+A positive return value indicates:
+
+<ul>
+<li>The vertices are wrapped in the normal Detour wrap direction.</li>
+<li>The triangle's 3D face normal is in the general up direction.</li>
+</ul>
+
+A negative return value indicates:
+
+<ul>
+<li>The vertices are reverse wrapped. (Wrapped opposite the normal Detour wrap direction.)</li>
+<li>The triangle's 3D face normal is in the general down direction.</li>

+@typedef dtPolyRef
+@par
+
+Polygon references are subject to the same invalidate/preserve/restore 
+rules that apply to #dtTileRef's.  If the #dtTileRef for the polygon's
+tile changes, the polygon reference becomes invalid.
+
+Changing a polygon's flags, area id, etc. does not impact its polygon
+reference.
+
+@typedef dtTileRef
+@par
+
+The following changes will invalidate a tile reference:
+
+- The referenced tile has been removed from the navigation mesh.
+- The navigation mesh has been initialized using a different set
+  of #dtNavMeshParams.
+
+A tile reference is preserved/restored if the tile is added to a navigation 
+mesh initialized with the original #dtNavMeshParams and is added at the
+original reference location. (E.g. The lastRef parameter is used with
+dtNavMesh::addTile.)
+
+Basically, if the storage structure of a tile changes, its associated
+tile reference changes.
+
+
+@var unsigned short dtPoly::neis[DT_VERTS_PER_POLYGON]
+@par
+
+Each entry represents data for the edge starting at the vertex of the same index. 
+E.g. The entry at index n represents the edge data for vertex[n] to vertex[n+1].
+
+A value of zero indicates the edge has no polygon connection. (It makes up the 
+border of the navigation mesh.)
+
+The information can be extracted as follows: 
+@code 
+neighborRef = neis[n] & 0xff; // Get the neighbor polygon reference.
+
+if (neis[n] & #DT_EX_LINK)
+{
+    // The edge is an external (portal) edge.
+}
+@endcode
+
+@var float dtMeshHeader::bvQuantFactor
+@par
+
+This value is used for converting between world and bounding volume coordinates.
+For example:
+@code
+const float cs = 1.0f / tile->header->bvQuantFactor;
+const dtBVNode* n = &tile->bvTree[i];
+if (n->i >= 0)
+{
+    // This is a leaf node.
+    float worldMinX = tile->header->bmin[0] + n->bmin[0]*cs;
+    float worldMinY = tile->header->bmin[0] + n->bmin[1]*cs;
+    // Etc...
+}
+@endcode
+
+@struct dtMeshTile
+@par
+
+Tiles generally only exist within the context of a dtNavMesh object.
+
+Some tile content is optional.  For example, a tile may not contain any
+off-mesh connections.  In this case the associated pointer will be null.
+
+If a detail mesh exists it will share vertices with the base polygon mesh.  
+Only the vertices unique to the detail mesh will be stored in #detailVerts.
+
+@warning Tiles returned by a dtNavMesh object are not guarenteed to be populated.
+For example: The tile at a location might not have been loaded yet, or may have been removed.
+In this case, pointers will be null.  So if in doubt, check the polygon count in the 
+tile's header to determine if a tile has polygons defined.
+
+@var float dtOffMeshConnection::pos[6]
+@par
+
+For a properly built navigation mesh, vertex A will always be within the bounds of the mesh. 
+Vertex B is not required to be within the bounds of the mesh.

-//   instead of accessing your own objects where possible.
-// - You do not need to adhere to the flags and cost logic provided by the default

+@class dtNavMesh
+
+The navigation mesh consists of one or more tiles defining three primary types of structural data:
+
+A polygon mesh which defines most of the navigation graph. (See rcPolyMesh for its structure.)
+A detail mesh used for determining surface height on the polygon mesh. (See rcPolyMeshDetail for its structure.)
+Off-mesh connections, which define custom point-to-point edges within the navigation graph.
+
+The general build process is as follows:
+
+-# Create rcPolyMesh and rcPolyMeshDetail data using the Recast build pipeline.
+-# Optionally, create off-mesh connection data.
+-# Combine the source data into a dtNavMeshCreateParams structure.
+-# Create a tile data array using dtCreateNavMeshData().
+-# Allocate at dtNavMesh object and initialize it. (For single tile navigation meshes,
+   the tile data is loaded during this step.)
+-# For multi-tile navigation meshes, load the tile data using dtNavMesh::addTile().
+
+Notes:
+
+- This class is usually used in conjunction with the dtNavMeshQuery class for pathfinding.
+- Technically, all navigation meshes are tiled. A 'solo' mesh is simply a navigation mesh initialized 
+  to have only a single tile.
+- This class does not implement any asynchronous methods. So the ::dtStatus result of all methods will 
+  always contain either a success or failure flag.
+
+@see dtNavMeshQuery, dtCreateNavMeshData, dtNavMeshCreateParams, #dtAllocNavMesh, #dtFreeNavMesh

+/// <b>The Default Implementation</b>
+/// 
+/// At construction: All area costs default to 1.0.  All flags are included
+/// and none are excluded.
+/// 
+/// If a polygon has both an include and an exclude flag, it will be excluded.
+/// 
+/// The way filtering works, a navigation mesh polygon must have at least one flag 
+/// set to ever be considered by a query. So a polygon with no flags will never
+/// be considered.
+///
+/// Setting the include flags to 0 will result in all polygons being excluded.
+///
+/// <b>Custom Implementations</b>
+/// 
+/// DT_VIRTUAL_QUERYFILTER must be defined in order to extend this class.
+/// 
+/// Implement a custom query filter by overriding the virtual passFilter() 
+/// and getCost() functions. If this is done, both functions should be as 
+/// fast as possible. Use cached local copies of data rather than accessing 
+/// your own objects where possible.
+/// 
+/// Custom implementations do not need to adhere to the flags or cost logic 
+/// used by the default implementation.  
+/// 
+/// In order for A* searches to work properly, the cost should be proportional to
+/// the travel distance. Implementing a cost modifier less than 1.0 is likely 
+/// to lead to problems during pathfinding.

+/// This method is meant to be used for quick, short distance checks.
+///
+/// If the path array is too small to hold the result, it will be filled as 
+/// far as possible from the start postion toward the end position.
+///
+/// <b>Using the Hit Parameter t of RaycastHit</b>
+/// 
+/// If the hit parameter is a very high value (FLT_MAX), then the ray has hit 
+/// the end position. In this case the path represents a valid corridor to the 
+/// end position and the value of @p hitNormal is undefined.
+///
+/// If the hit parameter is zero, then the start position is on the wall that 
+/// was hit and the value of @p hitNormal is undefined.
+///
+/// If 0 < t < 1.0 then the following applies:
+///
+/// @code
+/// distanceToHitBorder = distanceToEndPosition * t
+/// hitPoint = startPos + (endPos - startPos) * t
+/// @endcode
+///
+/// <b>Use Case Restriction</b>
+///
+/// The raycast ignores the y-value of the end position. (2D check.) This 
+/// places significant limits on how it can be used. For example:
+///
+/// Consider a scene where there is a main floor with a second floor balcony 
+/// that hangs over the main floor. So the first floor mesh extends below the 
+/// balcony mesh. The start position is somewhere on the first floor. The end 
+/// position is on the balcony.
+///
+/// The raycast will search toward the end position along the first floor mesh. 
+/// If it reaches the end position's xz-coordinates it will indicate FLT_MAX
+/// (no wall hit), meaning it reached the end position. This is one example of why
+/// this method is meant for short distance checks.

+
+@defgroup crowd Crowd
+
+Members in this module implement local steering and dynamic avoidance features.
+
+The crowd is the big beast of the navigation features. It not only handles a 
+lot of the path management for you, but also local steering and dynamic 
+avoidance between members of the crowd. I.e. It can keep your agents from 
+running into each other.
+
+Main class: #dtCrowd
+
+The #dtNavMeshQuery and #dtPathCorridor classes provide perfectly good, easy 
+to use path planning features. But in the end they only give you points that 
+your navigation client should be moving toward. When it comes to deciding things 
+like agent velocity and steering to avoid other agents, that is up to you to 
+implement. Unless, of course, you decide to use #dtCrowd.
+
+Basically, you add an agent to the crowd, providing various configuration 
+settings such as maximum speed and acceleration. You also provide a local 
+target to more toward. The crowd manager then provides, with every update, the 
+new agent position and velocity for the frame. The movement will be 
+constrained to the navigation mesh, and steering will be applied to ensure 
+agents managed by the crowd do not collide with each other.
+
+This is very powerful feature set. But it comes with limitations.
+
+The biggest limitation is that you must give control of the agent's position 
+completely over to the crowd manager. You can update things like maximum speed 
+and acceleration. But in order for the crowd manager to do its thing, it can't 
+allow you to constantly be giving it overrides to position and velocity. So 
+you give up direct control of the agent's movement. It belongs to the crowd.
+
+The second biggest limitation revolves around the fact that the crowd manager 
+deals with local planning. So the agent's target should never be more than 
+256 polygons aways from its current position. If it is, you risk 
+your agent failing to reach its target. So you may still need to do long 
+distance planning and provide the crowd manager with intermediate targets.
+
+Other significant limitations:
+
+- All agents using the crowd manager will use the same #dtQueryFilter.
+- Crowd management is relatively expensive. The maximum agents under crowd 
+  management at any one time is between 20 and 30.  A good place to start
+  is a maximum of 25 agents for 0.5ms per frame.
+
+@note This is a summary list of members.  Use the index or search 
+feature to find minor members.
+
+@struct dtCrowdAgentParams
+@see dtCrowdAgent, dtCrowd::addAgent(), dtCrowd::updateAgentParameters()
+
+@var dtCrowdAgentParams::obstacleAvoidanceType
+@par
+
+#dtCrowd permits agents to use different avoidance configurations.  This value 
+is the index of the #dtObstacleAvoidanceParams within the crowd.
+
+@see dtObstacleAvoidanceParams, dtCrowd::setObstacleAvoidanceParams(), 
+	 dtCrowd::getObstacleAvoidanceParams()
+
+@var dtCrowdAgentParams::collisionQueryRange
+@par
+
+Collision elements include other agents and navigation mesh boundaries.
+
+This value is often based on the agent radius and/or maximum speed. E.g. radius * 8
+
+@var dtCrowdAgentParams::pathOptimizationRange
+@par
+
+Only applicalbe if #updateFlags includes the #DT_CROWD_OPTIMIZE_VIS flag.
+
+This value is often based on the agent radius. E.g. radius * 30
+
+@see dtPathCorridor::optimizePathVisibility()
+
+@var dtCrowdAgentParams::separationWeight
+@par
+
+A higher value will result in agents trying to stay farther away from each other at 
+the cost of more difficult steering in tight spaces.

+/**
+@class dtCrowd
+@par
+
+This is the core class of the @ref crowd module.  See the @ref crowd documentation for a summary
+of the crowd features.
+
+A common method for setting up the crowd is as follows:
+
+-# Allocate the crowd using #dtAllocCrowd.
+-# Initialize the crowd using #init().
+-# Set the avoidance configurations using #setObstacleAvoidanceParams().
+-# Add agents using #addAgent() and make an initial movement request using #requestMoveTarget().
+
+A common process for managing the crowd is as follows:
+
+-# Call #update() to allow the crowd to manage its agents.
+-# Retrieve agent information using #getActiveAgents().
+-# Make movement requests using #requestMoveTarget() when movement goal changes.
+-# Repeat every frame.
+
+Some agent configuration settings can be updated using #updateAgentParameters().  But the crowd owns the
+agent position.  So it is not possible to update an active agent's position.  If agent position
+must be fed back into the crowd, the agent must be removed and re-added.
+
+Notes: 
+
+- Path related information is available for newly added agents only after an #update() has been
+  performed.
+- Agent objects are kept in a pool and re-used.  So it is important when using agent objects to check the value of
+  #dtCrowdAgent::active to determine if the agent is actually in use or not.
+- This class is meant to provide 'local' movement. There is a limit of 256 polygons in the path corridor.  
+  So it is not meant to provide automatic pathfinding services over long distances.

+@class dtPathCorridor
+@par
+
+The corridor is loaded with a path, usually obtained from a #dtNavMeshQuery::findPath() query. The corridor
+is then used to plan local movement, with the corridor automatically updating as needed to deal with inaccurate 
+agent locomotion.
+
+Example of a common use case:
+
+-# Construct the corridor object and call #init() to allocate its path buffer.
+-# Obtain a path from a #dtNavMeshQuery object.
+-# Use #reset() to set the agent's current position. (At the beginning of the path.)
+-# Use #setCorridor() to load the path and target.
+-# Use #findCorners() to plan movement. (This handles dynamic path straightening.)
+-# Use #movePosition() to feed agent movement back into the corridor. (The corridor will automatically adjust as needed.)
+-# If the target is moving, use #moveTargetPosition() to update the end of the corridor. 
+   (The corridor will automatically adjust as needed.)
+-# Repeat the previous 3 steps to continue to move the agent.
+
+The corridor position and target are always constrained to the navigation mesh.
+
+One of the difficulties in maintaining a path is that floating point errors, locomotion inaccuracies, and/or local 
+steering can result in the agent crossing the boundary of the path corridor, temporarily invalidating the path. 
+This class uses local mesh queries to detect and update the corridor as needed to handle these types of issues. 
+
+The fact that local mesh queries are used to move the position and target locations results in two beahviors that 
+need to be considered:
+
+Every time a move function is used there is a chance that the path will become non-optimial. Basically, the further 
+the target is moved from its original location, and the further the position is moved outside the original corridor, 
+the more likely the path will become non-optimal. This issue can be addressed by periodically running the 
+#optimizePathTopology() and #optimizePathVisibility() methods.
+
+All local mesh queries have distance limitations. (Review the #dtNavMeshQuery methods for details.) So the most accurate 
+use case is to move the position and target in small increments. If a large increment is used, then the corridor 
+may not be able to accurately find the new location.  Because of this limiation, if a position is moved in a large
+increment, then compare the desired and resulting polygon references. If the two do not match, then path replanning 
+may be needed.  E.g. If you move the target, check #getLastPoly() to see if it is the expected polygon.

+detected in order to plan movement. It performs essentially the same function as #dtNavMeshQuery::findStraightPath.

+For example: If the buffers are sized to hold 10 corners, the function will never return more than 9 corners. 
+So if 10 corners are needed, the buffers should be sized for 11 corners.
+
+If the target is within range, it will be the last corner and have a polygon reference id of zero.

+///
+/// <h2>Recast</h2>
+/// 
+/// _Recast_ is state of the art navigation mesh construction toolset for 
+/// games.
+///
+/// - It is automatic, which means that you can throw any level 
+///   geometry at it and you will get a robust mesh out.
+/// - It is fast which means swift turnaround times for level designers.
+/// - It is open source so it comes with full source and you can 
+///   customize it to your hearts content.
+/// 
+/// The latest version can be found on 
+/// <a href="https://github.com/memononen/recastnavigation">GitHub</a>.
+/// 
+/// The _Recast_ process starts with constructing a voxel mold from level
+/// geometry and then casting a navigation mesh over it. The process 
+/// consists of three steps, building the voxel mold, partitioning the
+/// mold into simple regions, and peeling off the regions as simple polygons.
+/// 
+/// -# The voxel mold is built from the input triangle mesh by 
+///    rasterizing the triangles into a multi-layer heightfield. Some 
+///    simple filters are then applied to the mold to prune out locations 
+///    where the character would not be able to move.
+/// -# The walkable areas described by the mold are divided into simple 
+///    overlayed 2D regions. The resulting regions have only one 
+///    non-overlapping contour, which simplifies the final step of the 
+///    process tremendously.
+/// -# The navigation polygons are peeled off from the regions by first 
+///    tracing the boundaries and then simplifying them. The resulting 
+///    polygons are finally converted to convex polygons which makes them 
+///    perfect for pathfinding and spatial reasoning about the level. 
+/// 
+/// <h2>Detour</h2>
+///
+/// _Recast_ is accompanied by _Detour_, a path-finding and spatial reasoning 
+/// toolkit. You can use any navigation mesh with _Detour_, but of course 
+/// the data generated by _Recast_ fits perfectly. 
+///
+/// _Detour_ offers a simple static navigation mesh that is suitable for 
+/// many simple cases, as well as a tiled navigation mesh that allows you 
+/// to add and remove pieces of the mesh. The tiled mesh allows you to 
+/// create systems where you stream new navigation data in and out as 
+/// the player progresses the level, or regenerate tiles as the 
+/// world changes. 
+///
+/// <h2>Recast Demo</h2>
+///
+/// You can find a comprehensive demo project in the `RecastDemo` folder. It 
+/// is a kitchen sink demo containing all the functionality of the library. 
+/// If you are new to _Recast_ & _Detour_, check out 
+/// <a href="https://github.com/memononen/recastnavigation/blob/master/RecastDemo/Source/Sample_SoloMesh.cpp">
+/// Sample_SoloMesh.cpp</a> to get started with building navmeshes and 
+/// <a href="https://github.com/memononen/recastnavigation/blob/master/RecastDemo/Source/NavMeshTesterTool.cpp">
+/// NavMeshTesterTool.cpp</a> to see how _Detour_ can be used to find paths.
+///
+/// <h3>Building RecastDemo</h3>
+///
+/// _RecastDemo_ uses <a href="http://industriousone.com/premake">premake4</a>
+/// to build platform specific projects, now is good time to install it if 
+/// you don't have it already. To build _RecastDemo_, in your favourite terminal
+///  navigate into the `RecastDemo` folder, then:
+///
+/// - OS X: `premake4 xcode4`
+/// - Windows: `premake4 vs2010`
+/// - Linux: `premake4 gmake`
+///
+/// See the _premake4_ documentation for full list of supported build file types.
+/// The projects will be created in the `RecastDemo/Build` folder.  After you have
+/// compiled the project, the _RecastDemo_ executable will be located in 
+/// `RecastDemo/Bin` folder.
+///
+/// <h2>Integrating With Your Own Project</h2>
+///
+/// It is recommended to add the source directories `DebugUtils`, `Detour`,
+/// `DetourCrowd`, `DetourTileCache`, and `Recast` into your own project 
+/// depending on which parts of the project you need. For example your 
+/// level building tool could include `DebugUtils`, `Recast`, and `Detour`, 
+/// and your game runtime could just include `Detour`.
+///

+@defgroup recast Recast
+
+Members in this module are used to create mesh data that is then
+used to create Detour navigation meshes.
+
+The are a large number of possible ways to building navigation mesh data.
+One of the simple piplines is as follows:
+
+-# Prepare the input triangle mesh.
+-# Build a #rcHeightfield.
+-# Build a #rcCompactHeightfield.
+-# Build a #rcContourSet.
+-# Build a #rcPolyMesh.
+-# Build a #rcPolyMeshDetail.
+-# Use the rcPolyMesh and rcPolyMeshDetail to build a Detour navigation mesh
+   tile.
+
+The general life-cycle of the main classes is as follows:
+
+-# Allocate the object using the Recast allocator. (E.g. #rcAllocHeightfield)
+-# Initialize or build the object. (E.g. #rcCreateHeightfield)
+-# Update the object as needed. (E.g. #rcRasterizeTriangles)
+-# Use the object as part of the pipeline.
+-# Free the object using the Recast allocator. (E.g. #rcFreeHeightField)
+
+@note This is a summary list of members.  Use the index or search 
+feature to find minor members.
+
+@struct rcConfig
+@par
+
+The is a convenience structure that represents an aggregation of parameters 
+used at different stages in the Recast build process. Some 
+values are derived during the build process. Not all parameters 
+are used for all build processes.
+
+Units are usually in voxels (vx) or world units (wu).  The units for voxels, 
+grid size, and cell size are all based on the values of #cs and #ch.
+
+In this documentation, the term 'field' refers to heightfield and
+contour data structures that define spacial information using an integer
+grid.
+
+The upper and lower limits for the various parameters often depend on 
+the platform's floating point accuraccy as well as interdependencies between 
+the values of multiple parameters.  See the individual parameter 
+documentation for details.
+
+@var rcConfig::borderSize
+@par
+
+This value represents the the closest the walkable area of the heightfield 
+should come to the xz-plane AABB of the field. It does not have any
+impact on the borders around internal obstructions.
+
+@var rcConfig::tileSize
+@par
+
+This field is only used when building multi-tile meshes.
+
+@var rcConfig::cs
+@par
+
+@p cs and #ch define voxel/grid/cell size.  So their values have significant 
+side effects on all parameters defined in voxel units.
+
+The minimum value for this parameter depends on the platform's floating point 
+accuracy, with the practical minimum usually around 0.05.
+
+@var rcConfig::ch
+@par
+
+#cs and @p ch define voxel/grid/cell size.  So their values have significant 
+side effects on all parameters defined in voxel units.
+
+The minimum value for this parameter depends on the platform's floating point 
+accuracy, with the practical minimum usually around 0.05.
+
+@var rcConfig::walkableSlopeAngle
+@par
+
+The practical upper limit for this parameter is usually around 85 degrees.
+
+@var rcConfig::walkableHeight
+@par
+
+Permits detection of overhangs in the source geometry that make the geometry
+below un-walkable. The value is usually set to the maximum agent height.
+
+@var rcConfig::walkableClimb
+@par
+
+Allows the mesh to flow over low lying obstructions such as curbs and 
+up/down stairways. The value is usually set to how far up/down an agent can step.
+
+@var rcConfig::walkableRadius
+@par
+
+In general, this is the closest any part of the final mesh should get to an 
+obstruction in the source geometry.  It is usually set to the maximum
+agent radius.
+
+While a value of zero is legal, it is not recommended and can result in
+odd edge case issues.
+
+@var rcConfig::maxEdgeLen
+@par
+
+Extra vertices will be inserted as needed to keep contour edges below this
+length. A value of zero effectively disables this feature.
+
+@var rcConfig::maxSimplificationError
+@par
+
+The effect of this parameter only applies to the xz-plane.
+
+@var rcConfig::minRegionArea
+@par
+
+Any regions that are smaller than this area will be marked as unwalkable.
+This is useful in removing useless regions that can sometimes form on 
+geometry such as table tops, box tops, etc.
+
+@var rcConfig::maxVertsPerPoly
+@par
+
+If the mesh data is to be used to construct a Detour navigation mesh, then the upper limit
+is limited to <= #DT_VERTS_PER_POLYGON.
+
+
+@struct rcHeightfield
+@par
+
+The grid of a heightfield is layed out on the xz-plane based on the
+value of #cs.  Spans exist within the grid columns with the span
+min/max values at increments of #ch from the base of the grid.  The smallest 
+possible span size is <tt>(#cs width) * (#cs depth) * (#ch height)</tt>. (Which is a single voxel.)
+
+The standard process for buidling a heightfield is to allocate it using
+#rcAllocHeightfield, initialize it using #rcCreateHeightfield, then
+add spans using the various helper functions such as #rcRasterizeTriangle.
+
+Building a heightfield is one of the first steps in creating a polygon mesh
+from source geometry.  After it is populated, it is used to build a 
+rcCompactHeightfield.
+
+Example of iterating the spans in a heightfield:
+@code
+// Where hf is a reference to an heightfield object.
+
+const float* orig = hf.bmin;
+const float cs = hf.cs;
+const float ch = hf.ch;
+
+const int w = hf.width;
+const int h = hf.height;
+
+for (int y = 0; y < h; ++y)
+{
+    for (int x = 0; x < w; ++x)
+    {
+        // Deriving the minimum corner of the grid location.
+        float fx = orig[0] + x*cs;
+        float fz = orig[2] + y*cs;
+        // The base span in the column. (May be null.)
+        const rcSpan* s = hf.spans[x + y*w]; 
+        while (s)
+        {
+            // Detriving the minium and maximum world position of the span.
+            float fymin = orig[1]+s->smin*ch;
+            float fymax = orig[1] + s->smax*ch;
+            // Do other things with the span before moving up the column.
+            s = s->next;
+        }
+    }
+}
+@endcode
+
+@see rcAllocHeightfield, rcFreeHeightField, rcCreateHeightfield
+
+@struct rcCompactCell
+@par
+
+See the rcCompactHeightfield documentation for an example of how compact cells
+are used to iterate the heightfield.
+
+Useful instances of this type can only by obtained from a #rcCompactHeightfield object.
+
+@see rcCompactHeightfield
+
+@struct rcCompactSpan
+@par
+
+The span represents open, unobstructed space within a compact heightfield column.
+See the rcCompactHeightfield documentation for an example of iterating spans and searching 
+span connections.
+
+Useful instances of this type can only by obtained from a #rcCompactHeightfield object.
+
+@see rcCompactHeightfield
+
+
+@struct rcCompactHeightfield
+@par
+
+For this type of heightfield, the spans represent the open (unobstructed) 
+space above the solid surfaces of a voxel field. It is usually created from 
+a #rcHeightfield object.  Data is stored in a compact, efficient manner,  
+but the structure is not condusive to adding and removing spans.
+
+The standard process for buidling a compact heightfield is to allocate it 
+using #rcAllocCompactHeightfield, build it using #rcBuildCompactHeightfield,
+then run it through the various helper functions to generate neighbor
+and region data.
+
+Connected neighbor spans form non-overlapping surfaces.  When neighbor 
+information is generated, spans will include data that can be used to 
+locate axis-neighbors. Axis-neighbors are connected
+spans that are offset from the current cell column as follows:
+<pre>
+Direction 0 = (-1, 0)
+Direction 1 = (0, 1)
+Direction 2 = (1, 0)
+Direction 3 = (0, -1)
+</pre>
+
+Example of iterating and inspecting spans, including connected neighbors:
+
+@code
+// Where chf is an instance of a rcCompactHeightfield.
+
+const float cs = chf.cs;
+const float ch = chf.ch;
+
+for (int y = 0; y < chf.height; ++y)
+{
+    for (int x = 0; x < chf.width; ++x)
+    {
+        // Deriving the minimum corner of the grid location.
+        const float fx = chf.bmin[0] + x*cs;
+        const float fz = chf.bmin[2] + y*cs;
+
+        // Get the cell for the grid location then iterate
+        // up the column.
+        const rcCompactCell& c = chf.cells[x+y*chf.width];
+        for (unsigned i = c.index, ni = c.index+c.count; i < ni; ++i)
+        {
+            const rcCompactSpan& s = chf.spans[i];
+
+            Deriving the minimum (floor) of the span.
+            const float fy = chf.bmin[1] + (s.y+1)*ch;
+
+            // Testing the area assignment of the span.
+            if (chf.areas[i] == RC_WALKABLE_AREA)
+            { 
+                // The span is in the default 'walkable area'.
+            }
+            else if (chf.areas[i] == RC_NULL_AREA)
+            { 
+                // The surface is not considered walkable.
+                // E.g. It was filtered out during the build processes.
+            }
+            else
+            { 
+                // Do something. (Only applicable for custom build
+                // build processes.)
+            }
+
+            // Iterating the connected axis-neighbor spans.
+            for (int dir = 0; dir < 4; ++dir)
+            {
+                if (rcGetCon(s, dir) != RC_NOT_CONNECTED)
+                {
+                    // There is a neighbor in this direction.

+@struct rcContour
+@par
+
+A contour only exists within the context of a #rcContourSet object.
+
+While the height of the contour's border may vary, the contour will always 
+form a simple polygon when projected onto the xz-plane.
+
+Example of converting vertices into world space:
+
+@code
+// Where cset is the rcContourSet object to which the contour belongs.
+float worldX = cset.bmin[0] + vertX * cset.cs;
+float worldY = cset.bmin[1] + vertY * cset.ch;
+float worldZ = cset.bmin[2] + vertZ * cset.cs;
+@endcode
+
+@see rcContourSet
+
+@var rcContour::verts
+@par
+
+The simplified contour is a version of the raw contour with all 
+'unnecessary' vertices removed. Whether a vertex is 
+considered unnecessary depends on the contour build process.
+
+The data format is as follows: (x, y, z, r) * #nverts
+
+A contour edge is formed by the current and next vertex. The r-value 
+represents region and connection information for the edge. For example:
+
+@code
+int r = verts[i*4+3];
+
+int regionId = r & RC_CONTOUR_REG_MASK;
+
+if (r & RC_BORDER_VERTEX)
+{
+    // The edge represents a solid border.
+}
+
+if (r & RC_AREA_BORDER)
+{
+    // The edge represents a transition between different areas.
+}
+@endcode
+
+@var rcContour::rverts
+@par
+
+See #verts for information on element layout.
+
+@struct rcContourSet
+@par
+
+All contours within the set share the minimum bounds and cell sizes of the set.
+
+The standard process for building a contour set is to allocate it
+using #rcAllocContourSet, then initialize it using #rcBuildContours.
+
+@see rcAllocContourSet, rcFreeContourSet, rcBuildContours

+@par
+
+A mesh of potentially overlapping convex polygons of between three 
+and #nvp vertices. The mesh exists within the context of an axis-aligned 
+bounding box (AABB) with vertices laid out in an evenly spaced grid, based 
+on the values of #cs and #ch.
+
+The standard process for building a contour set is to allocate it using
+#rcAllocPolyMesh, the initialize it using #rcBuildPolyMesh
+
+Example of iterating the polygons:
+
+@code
+// Where mesh is a reference to a rcPolyMesh object.
+
+const int nvp = mesh.nvp;
+const float cs = mesh.cs;
+const float ch = mesh.ch;
+const float* orig = mesh.bmin;
+
+for (int i = 0; i < mesh.npolys; ++i)
+{
+   const unsigned short* p = &mesh.polys[i*nvp*2];
+   
+    // Iterate the vertices.
+   unsigned short vi[3];  // The vertex indices.
+   for (int j = 0; j < nvp; ++j)
+   {
+      if (p[j] == RC_MESH_NULL_IDX) 
+            break; // End of vertices.
+
+        if (p[j + nvp] == RC_MESH_NULL_IDX)
+        {
+            // The edge beginning with this vertex is a solid border.
+        }
+        else
+        {
+            // The edge beginning with this vertex connects to 
+            // polygon p[j + nvp].
+        }
+        
+        // Convert to world space.
+       const unsigned short* v = &mesh.verts[p[j]*3];
+      const float x = orig[0] + v[0]*cs;
+      const float y = orig[1] + v[1]*ch;
+      const float z = orig[2] + v[2]*cs;
+      // Do something with the vertices.
+   }
+}
+@endcode
+
+@see rcAllocPolyMesh, rcFreePolyMesh, rcBuildPolyMesh
+
+@var rcPolyMesh::verts
+@par
+
+The values of #bmin ,#cs, and #ch are used to convert vertex coordinates
+to world space as follows:
+
+@code
+float worldX = bmin[0] + verts[i*3+0] * cs
+float worldY = bmin[1] + verts[i*3+1] * ch
+float worldZ = bmin[2] + verts[i*3+2] * cs
+@endcode
+
+@var rcPolyMesh::polys
+@par
+
+Each entry is <tt>2 * #nvp</tt> in length. The first half of the entry 
+contains the indices of the polygon. The first instance of #RC_MESH_NULL_IDX
+indicates the end of the indices for the entry. The second half contains 
+indices to neighbor polygons. A value of #RC_MESH_NULL_IDX indicates no 
+connection for the associated edge. (I.e. The edge is a solid border.)
+
+For example:
+<pre>
+nvp = 6
+For the entry: (1, 3, 4, 8, RC_MESH_NULL_IDX, RC_MESH_NULL_IDX, 
+                18, RC_MESH_NULL_IDX , 21, RC_MESH_NULL_IDX, RC_MESH_NULL_IDX, RC_MESH_NULL_IDX)
+
+(1, 3, 4, 8) defines a polygon with 4 vertices.
+Edge 1->3 is shared with polygon 18.
+Edge 4->8 is shared with polygon 21.
+Edges 3->4 and 4->8 are border edges not shared with any other polygon.
+</pre>
+
+@var rcPolyMesh::areas
+@par
+
+The standard build process assigns the value of #RC_WALKABLE_AREA to all walkable polygons.
+This value can then be changed to meet user requirements.
+
+@struct rcPolyMeshDetail
+@par
+
+The detail mesh is made up of triangle sub-meshes that provide extra 
+height detail for each polygon in its assoicated polygon mesh.
+
+The standard process for building a detail mesh is to allocate it 
+using #rcAllocPolyMeshDetail, then build it using #rcBuildPolyMeshDetail.
+
+See the individual field definitions for details realted to the structure
+the mesh.
+
+@see rcAllocPolyMeshDetail, rcFreePolyMeshDetail, rcBuildPolyMeshDetail, rcPolyMesh
+
+@var rcPolyMeshDetail::meshes

+
+[(baseVertIndex, vertCount, baseTriIndex, triCount) * #nmeshes]
+
+Maximum number of vertices per sub-mesh: 127<br/>
+Maximum number of triangles per sub-mesh: 255
+
+The sub-meshes are stored in the same order as the polygons from the
+rcPolyMesh they represent.  E.g. rcPolyMeshDetail sub-mesh 5 is associated
+with #rcPolyMesh polygon 5.
+
+Example of iterating the triangles in a sub-mesh.
+
+@code
+// Where dmesh is a reference to a rcPolyMeshDetail object.
+
+// Iterate the sub-meshes. (One for each source polygon.)
+for (int i = 0; i < dmesh.nmeshes; ++i)

+	const unsigned int* meshDef = &dmesh.meshes[i*4];
+	const unsigned int baseVerts = meshDef[0];
+	const unsigned int baseTri = meshDef[2];
+	const int ntris = (int)meshDef[3];	
+	
+	const float* verts = &dmesh.verts[baseVerts*3];
+	const unsigned char* tris = &dmesh.tris[baseTri*4];
+
+    // Iterate the sub-mesh's triangles.
+	for (int j = 0; j < ntris; ++j)
+	{
+		const float x = verts[tris[j*4+0]*3];
+		const float y = verts[tris[j*4+1]*3];
+		const float z = verts[tris[j*4+2]*3];
+		// Do something with the vertex.
+	}
+}
+@endcode
+
+@var rcPolyMeshDetail::verts
+@par
+
+[(x, y, z) * #nverts] 
+
+The vertices are grouped by sub-mesh and will contain duplicates since 
+each sub-mesh is independently defined.
+
+The first group of vertices for each sub-mesh are in the same order as 
+the vertices for the sub-mesh's associated PolyMesh polygon. These 
+vertices are followed by any additional detail vertices. So it the 
+associated polygon has 5 vertices, the sub-mesh will have a minimum 
+of 5 vertices and the first 5 vertices will be equivalent to the 5 
+polygon vertices.
+
+@var rcPolyMeshDetail::tris
+@par
+
+[(vertIndexA, vertIndexB, vertIndexC, flags) * #ntris] 
+
+The triangles are grouped by sub-mesh.
+
+<b>Vertex Indices</b>
+
+The vertex indices in the triangle array are local to the sub-mesh, not global. 
+To translate into an global index in the vertices array, the values must be 
+offset by the sub-mesh's base vertex index.
+
+Example: If the baseVertexIndex for the sub-mesh is 5 and the triangle entry 
+is (4, 8, 7, 0), then the actual indices for the vertices are (4 + 5, 8 + 5, 7 + 5).
+
+@b Flags
+
+The flags entry indicates which edges are internal and which are external to 
+the sub-mesh. Internal edges connect to other triangles within the same sub-mesh. 
+External edges represent portals to other sub-meshes or the null region.
+
+Each flag is stored in a 2-bit position. Where position 0 is the lowest 2-bits 
+and position 4 is the highest 2-bits:
+
+<tt>
+Position 0: Edge AB (>> 0)<br/>
+Position 1: Edge BC (>> 2)<br/>
+Position 2: Edge CA (>> 4)<br/>
+Position 4: Unused<br/>
+</tt>
+
+Testing can be performed as follows:
+
+@code
+if (((flags >> 2) & 0x3) != 0)
+{
+    // Edge BC is an external edge.
+}
+@endcode
+
+@fn void rcSetCon(rcCompactSpan &s, int dir, int i)
+@par
+
+This function is used by the build process. It is rarely of use to end users.
+
+@see #rcCompactHeightfield, #rcCompactSpan
+
+@fn int rcGetCon(const rcCompactSpan &s, int dir)
+@par

+
+    The target for the Doxygen build.  (Created during the build process.)
+    
+Miscellany
+
+One of the requirements for the API documentation is that it
+has the minimum possible impact on the declarations in the
+header files.  So, in general, the header file declarations only
+contain summary documentation.  The detail documentation
+is placed as follows:
+
+1.  If an element is defined in a cpp file, then place
+    the detail documentation in the source file.
+2.  If an element does not have an associated cpp file, then
+    place the detail documentation at the end of the header file.
+3.  If there is a lot of detail documentation cluttering up
+    the end of a header file, then the content is moved to 
+	a separate file in the Extern directory.
+    
+Building the Documentation
+
+1.  Download and install the appropriate Doxygen version.  (See the first 
+    line in the Doxyfile for the current version.)
+2.  Run "doxygen" in the project root directory. (The location of the Doxyfile.)
+    No arguments are required.
+
+The generated html files will be located in the /Docs/html directory.
+
+If you want to "version" the documentation, you can set the PROJECT_NUMBER
+setting in the Doxyfile.  E.g. PROJECT_NUMBER = "(2014-04-23)".  The project
+number will be added to the header of the documentation.  
+E.g. "Recast Navigation (2014-04-23)"

+Recast & Detour
+===============
+
+[![Bitdeli Badge](https://d2weczhvl823v0.cloudfront.net/memononen/recastnavigation/trend.png)](https://bitdeli.com/free "Bitdeli Badge")
+
+![screenshot of a navmesh baked with the sample program](/RecastDemo/screenshot.png?raw=true)
+
+## Recast
+
+Recast is state of the art navigation mesh construction toolset for games.
+
+* It is automatic, which means that you can throw any level geometry at it and you will get robust mesh out
+* It is fast which means swift turnaround times for level designers
+* It is open source so it comes with full source and you can customize it to your heart's content. 
+
+The Recast process starts with constructing a voxel mold from a level geometry 
+and then casting a navigation mesh over it. The process consists of three steps, 
+building the voxel mold, partitioning the mold into simple regions, peeling off 
+the regions as simple polygons.
+
+1. The voxel mold is build from the input triangle mesh by rasterizing the triangles into a multi-layer heightfield. Some simple filters are  then applied to the mold to prune out locations where the character would not be able to move.
+2. The walkable areas described by the mold are divided into simple overlayed 2D regions. The resulting regions have only one non-overlapping contour, which simplifies the final step of the process tremendously.
+3. The navigation polygons are peeled off from the regions by first tracing the boundaries and then simplifying them. The resulting polygons are finally converted to convex polygons which makes them perfect for pathfinding and spatial reasoning about the level. 
+
+
+## Detour
+
+Recast is accompanied with Detour, path-finding and spatial reasoning toolkit. You can use any navigation mesh with Detour, but of course the data generated with Recast fits perfectly.
+
+Detour offers simple static navigation mesh which is suitable for many simple cases, as well as tiled navigation mesh which allows you to plug in and out pieces of the mesh. The tiled mesh allows you to create systems where you stream new navigation data in and out as the player progresses the level, or you may regenerate tiles as the world changes. 
+
+
+## Recast Demo
+
+You can find a comprehensive demo project in RecastDemo folder. It is a kitchen sink demo containing all the functionality of the library. If you are new to Recast & Detour, check out [Sample_SoloMesh.cpp](/RecastDemo/Source/Sample_SoloMesh.cpp) to get started with building navmeshes and [NavMeshTesterTool.cpp](/RecastDemo/Source/NavMeshTesterTool.cpp) to see how Detour can be used to find paths.
+
+### Building RecastDemo
+
+RecastDemo uses [premake4](http://industriousone.com/premake) to build platform specific projects, now is good time to install it if you don't have it already. To build *RecasDemo*, in your favorite terminal navigate into the `RecastDemo` folder, then:
+
+- *OS X*: `premake4 xcode4`
+- *Windows*: `premake4 vs2010`
+- *Linux*: `premake4 gmake`
+
+See premake4 documentation for full list of supported build file types. The projects will be created in `RecastDemo/Build` folder. And after you have compiled the project, the *RecastDemo* executable will be located in `RecastDemo/Bin` folder.
+
+
+## Integrating with your own project
+
+It is recommended to add the source directories `DebugUtils`, `Detour`, `DetourCrowd`, `DetourTileCache`, and `Recast` into your own project depending on which parts of the project you need. For example your level building tool could include DebugUtils, Recast, and Detour, and your game runtime could just include Detour.

-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.

-
-This is the Simple DirectMedia Layer, a general API that provides low
-level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
-and 2D framebuffer across multiple platforms.
-
-The current version supports Linux, Windows CE/95/98/ME/XP/Vista, BeOS,
-MacOS Classic, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX,
-and QNX.  The code contains support for Dreamcast, Atari, AIX, OSF/Tru64,
-RISC OS, SymbianOS, Nintendo DS, and OS/2, but these are not officially
-supported.
-
-SDL is written in C, but works with C++ natively, and has bindings to
-several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
-Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
-Pike, Pliant, Python, Ruby, and Smalltalk.
-
-This library is distributed under GNU LGPL version 2, which can be
-found in the file  "COPYING".  This license allows you to use SDL
-freely in commercial programs as long as you link with the dynamic
-library.
-
-The best way to learn how to use SDL is to check out the header files in
-the "include" subdirectory and the programs in the "test" subdirectory.
-The header files and test programs are well commented and always up to date.
-More documentation is available in HTML format in "docs/index.html", and
-a documentation wiki is available online at:
-	http://www.libsdl.org/cgi/docwiki.cgi
-
-The test programs in the "test" subdirectory are in the public domain.
-
-Frequently asked questions are answered online:
-	http://www.libsdl.org/faq.php
-
-If you need help with the library, or just want to discuss SDL related
-issues, you can join the developers mailing list:

-		</H3>
-		<p>

-				the SDL Download web site </A>, or you can build SDL yourself.
-		</p>
-		<H3>
-			Building SDL
-		</H3>
-		<P>
-			Unzip the <CODE>VisualC.zip</CODE> file into the directory that contains this 
-			file (<CODE>VisualC.html</CODE>).
-		</P>
-		<P>
-			Be certain that you unzip the zip file for your compiler into <strong>this</strong>
-			directory and not any other directory. If you are using WinZip, be careful to 
-			make sure that it extracts to <strong>this</strong> folder, because it's 
-			convenient feature of unzipping to a folder with the name of the file currently 
-			being unzipped will get you in trouble if you use it right now. And that's all 
-			I have to say about that.
-		</P>
-		<P>
-			Now that it's unzipped, go into the VisualC 
-			directory that is created, and double-click on the VC++ file "<CODE>SDL.dsw</CODE>"<STRONG><FONT color="#009900">
-					("<CODE>SDL.sln</CODE>").</FONT></STRONG> This should open up the IDE.
-		</P>
-		<P>
-			You may be prompted at this point to upgrade the workspace, should you be using 
-			a more recent version of Visual C++. If so, allow the workspace to be upgraded.
-		</P>
-		<P>
-			Build the <CODE>.dll</CODE> and <CODE>.lib</CODE> files.
-		</P>
-		<P>
-			This is done by right clicking on each project in turn (Projects are listed in 
-			the Workspace panel in the FileView tab), and selecting "Build".
-		</P>
-		<P>
-			If you get an error about SDL_config.h being missing, you should
-			copy include/SDL_config.h.default to include/SDL_config.h and try again.
-		</P>
-		<P>
-			You may get a few warnings, but you should not get any errors. You do have to 
-			have at least the DirectX 5 SDK installed, however. The latest 
-			version of DirectX can be downloaded or purchased on a cheap CD (my 
-			recommendation) from <A HREF="http://www.microsoft.com">Microsoft </A>.
-		</P>
-		<P>
-			Later, we will refer to the following .lib and .dll files that have just been 
-			generated:
-		</P>
-		<ul>
-    <li> SDL.dll</li>
-    <li> SDL.lib</li>
-    <li> SDLmain.lib</li>
-    </ul>
-		<P>
-			Search for these using the Windows Find (Windows-F) utility, if you don't 
-			already know where they should be. For those of you with a clue, look inside 
-			the Debug or Release directories of the subdirectories of the Project folder. 
-			(It might be easier to just use Windows Find if this sounds confusing. And 
-			don't worry about needing a clue; we all need visits from the clue fairy

-This is a list of API changes in SDL's version history.
-
-Version 1.0:
-
-1.2.14:
-	Added cast macros for correct usage with C++:
-		SDL_reinterpret_cast(type, expression)
-		SDL_static_cast(type, expression)
-
-	Added SDL_VIDEO_FULLSCREEN_DISPLAY as a preferred synonym for 
-	SDL_VIDEO_FULLSCREEN_HEAD on X11.
-
-	Added SDL_DISABLE_LOCK_KEYS environment variable to enable normal
-	up/down events for Caps-Lock and Num-Lock keys.
-
-1.2.13:
-	Added SDL_BUTTON_X1 and SDL_BUTTON_X2 constants.
-
-1.2.12:
-	Added SDL_VIDEO_ALLOW_SCREENSAVER to override SDL's disabling
-	of the screensaver on Mac OS X and X11.
-
-1.2.10:
-	If SDL_OpenAudio() is passed zero for the desired format
-	fields, the following environment variables will be used
-	to fill them in:
-		SDL_AUDIO_FREQUENCY
-		SDL_AUDIO_FORMAT
-		SDL_AUDIO_CHANNELS
-		SDL_AUDIO_SAMPLES
-	If an environment variable is not specified, it will be set
-	to a reasonable default value.
-
-	Added support for the SDL_VIDEO_FULLSCREEN_HEAD environment
-	variable, currently supported on X11 Xinerama configurations.
-
-	Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
-
-	Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
-
-	Added current_w and current_h to the SDL_VideoInfo structure,
-	which is set to the desktop resolution during video intialization,
-	and then set to the current resolution when a video mode is set.
-
-	SDL_SetVideoMode() now accepts 0 for width or height and will use
-	the current video mode (or the desktop mode if no mode has been set.)
-
-	Added SDL_GetKeyRepeat()
-
-	Added SDL_config.h, with defaults for various build environments.
-
-1.2.7:
-	Added CPU feature detection functions to SDL_cpuinfo.h:
-		SDL_HasRDTSC(), SDL_HasMMX(), SDL_Has3DNow(), SDL_HasSSE(),
-		SDL_HasAltiVec()
-	Added function to create RWops from const memory: SDL_RWFromConstMem()
-
-1.2.6:
-	Added SDL_LoadObject(), SDL_LoadFunction(), and SDL_UnloadObject()
-
-	Added SDL_GL_MULTISAMPLEBUFFERS and SDL_GL_MULTISAMPLESAMPLES for FSAA
-
-1.2.5:
-	Added SDL_BUTTON_WHEELUP (4) and SDL_BUTTON_WHEELDOWN (5)
-
-	Added SDL_GL_STEREO for stereoscopic OpenGL contexts
-
-1.2.0:
-	Added SDL_VIDEOEXPOSE event to signal that the screen needs to
-	be redrawn.  This is currently only delivered to OpenGL windows
-	on X11, though it may be delivered in the future when the video
-	memory is lost under DirectX.
-
-1.1.8:
-	You can pass SDL_NOFRAME to SDL_VideoMode() to create a window
-	that has no title bar or frame decoration.  Fullscreen video
-	modes automatically have this flag set.
-
-	Added a function to query the clipping rectangle for a surface:
-		void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect)
-
-	Added a function to query the current event filter:
-		SDL_EventFilter SDL_GetEventFilter(void)
-
-	If you pass -1 to SDL_ShowCursor(), it won't change the current
-	cursor visibility state, but will still return it.
-
-	SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning
-	you can nest them as deep as you want, as long as each lock call
-	has a matching unlock call.  The surface remains locked until the
-	last matching unlock call.
-
-	Note that you may not blit to or from a locked surface.
-
-1.1.7:
-	The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take
-	arrays of Uint16 values instead of Uint8 values.  For the most part,
-	you can just take your old values and shift them up 8 bits to get
-	new correct values for your gamma ramps.
-
-	You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface()
-        and SDL will try to RLE accelerate colorkey and alpha blits in the
-	resulting surface.
-
-1.1.6:
-	Added a function to return the thread ID of a specific thread:
-		Uint32 SDL_GetThreadID(SDL_Thread *thread)
-	If 'thread' is NULL, this function returns the id for this thread.
-
-1.1.5:
-	The YUV overlay structure has been changed to use an array of
-	pitches and pixels representing the planes of a YUV image, to
-	better enable hardware acceleration.  The YV12 and IYUV formats
-	each have three planes, corresponding to the Y, U, and V portions
-	of the image, while packed pixel YUV formats just have one plane.
-
-	For palettized mode (8bpp), the screen colormap is now split in
-	a physical and a logical palette. The physical palette determines
-	what colours the screen pixels will get when displayed, and the
-	logical palette controls the mapping from blits to/from the screen.
-	A new function, SDL_SetPalette() has been added to change
-	logical and physical palettes separately. SDL_SetColors() works
-	just as before, and is equivalent to calling SDL_SetPalette() with
-	a flag argument of (SDL_LOGPAL|SDL_PHYSPAL).
-
-	SDL_BlitSurface() no longer modifies the source rectangle, only the
-	destination rectangle. The width/height members of the destination
-	rectangle are ignored, only the position is used.
-
-	The old source clipping function SDL_SetClipping() has been replaced
-	with a more useful function to set the destination clipping rectangle:
-		SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect)
-		
-	Added a function to see what subsystems have been initialized:
-		Uint32 SDL_WasInit(Uint32 flags)
-
-	The Big Alpha Flip: SDL now treats alpha as opacity like everybody
-	else, and not as transparency:
-
-	A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255
-	A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0
-	Values between 0 and 255 vary from fully transparent to fully opaque.
-
-	New functions:
-	SDL_DisplayFormatAlpha()
-	    Returns a surface converted to a format with alpha-channel
-	    that can be blit efficiently to the screen. (In other words,
-	    like SDL_DisplayFormat() but the resulting surface has
-	    an alpha channel.)  This is useful for surfaces with alpha.
-	SDL_MapRGBA()
-	    Works as SDL_MapRGB() but takes an additional alpha parameter.
-	SDL_GetRGBA()
-	    Works as SDL_GetRGB() but also returns the alpha value
-	    (SDL_ALPHA_OPAQUE for formats without an alpha channel)
-
-	Both SDL_GetRGB() and SDL_GetRGBA() now always return values in
-	the [0..255] interval. Previously, SDL_GetRGB() would return
-	(0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format.
-	(N.B.: This is broken for bit fields < 3 bits.)
-
-	SDL_MapRGB() returns pixels in which the alpha channel is set opaque.
-
-	SDL_SetAlpha() can now be used for both setting the per-surface
-	alpha, using the new way of thinking of alpha, and also to enable
-	and disable per-pixel alpha blending for surfaces with an alpha
-	channel:
-		To disable alpha blending:
-			SDL_SetAlpha(surface, 0, 0);
-		To re-enable alpha blending:
-			SDL_SetAlpha(surface, SDL_SRCALPHA, 0);
-	Surfaces with an alpha channel have blending enabled by default.
-
-	SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests
-	RLE acceleration of blits, just as like with SDL_SetColorKey().
-	This flag can be set for both surfaces with an alpha channel
-	and surfaces with an alpha value set by SDL_SetAlpha().
-	As always, RLE surfaces must be locked before pixel access is
-	allowed, and unlocked before any other SDL operations are done
-	on it.
-
-	The blit semantics for surfaces with and without alpha and colorkey
-	have now been defined:
-
-	RGBA->RGB:
-	    SDL_SRCALPHA set:
-		alpha-blend (using alpha-channel).
-		SDL_SRCCOLORKEY ignored.
-	    SDL_SRCALPHA not set:
-		copy RGB.
-		if SDL_SRCCOLORKEY set, only copy the pixels matching the
-		RGB values of the source colour key, ignoring alpha in the
-		comparison.
-
-	RGB->RGBA:
-	    SDL_SRCALPHA set:
-		alpha-blend (using the source per-surface alpha value);
-		set destination alpha to opaque.
-	    SDL_SRCALPHA not set:
-		copy RGB, set destination alpha to opaque.
-	    both:
-		if SDL_SRCCOLORKEY set, only copy the pixels matching the
-		source colour key.
-
-	RGBA->RGBA:
-	    SDL_SRCALPHA set:
-		alpha-blend (using the source alpha channel) the RGB values;
-		leave destination alpha untouched. [Note: is this correct?]
-		SDL_SRCCOLORKEY ignored.
-	    SDL_SRCALPHA not set:
-		copy all of RGBA to the destination.
-		if SDL_SRCCOLORKEY set, only copy the pixels matching the
-		RGB values of the source colour key, ignoring alpha in the
-		comparison.
-
-	RGB->RGB: 
-	    SDL_SRCALPHA set:
-		alpha-blend (using the source per-surface alpha value).
-	    SDL_SRCALPHA not set:
-		copy RGB.
-	    both:
-		if SDL_SRCCOLORKEY set, only copy the pixels matching the
-		source colour key.
-
-	As a special case, blits from surfaces with per-surface alpha
-	value of 128 (50% transparency) are optimised and much faster
-	than other alpha values. This does not apply to surfaces with
-	alpha channels (per-pixel alpha).
-
-	New functions for manipulating the gamma of the display have
-	been added:
-		int SDL_SetGamma(float red, float green, float blue);
-		int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue);
-		int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue);
-	Gamma ramps are tables with 256 entries which map the screen color
-	components into actually displayed colors.  For an example of
-	implementing gamma correction and gamma fades, see test/testgamma.c
-	Gamma control is not supported on all hardware.
-
-1.1.4:
-	The size of the SDL_CDtrack structure changed from 8 to 12 bytes
-	as the size of the length member was extended to 32 bits.
-
-        You can now use SDL for 2D blitting with a GL mode by passing the
-	SDL_OPENGLBLIT flag to SDL_SetVideoMode().  You can specify 16 or
-	32 bpp, and the data in the framebuffer is put into the GL scene
-	when you call SDL_UpdateRects(), and the scene will be visible
-	when you call SDL_GL_SwapBuffers().
-
-	Run the "testgl" test program with the -logo command line option
-	to see an example of this blending of 2D and 3D in SDL.
-
-1.1.3:
-	Added SDL_FreeRW() to the API, to complement SDL_AllocRW()
-
-	Added resizable window support - just add SDL_RESIZABLE to the
-	SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events.
-	See SDL_events.h for details on the new SDL_ResizeEvent structure.
-
-	Added condition variable support, based on mutexes and semaphores.
-		SDL_CreateCond()
-		SDL_DestroyCond()
-		SDL_CondSignal()
-		SDL_CondBroadcast()
-		SDL_CondWait()
-		SDL_CondTimedWait()
-	The new function prototypes are in SDL_mutex.h
-
-	Added counting semaphore support, based on the mutex primitive.
-		SDL_CreateSemaphore()
-		SDL_DestroySemaphore()
-		SDL_SemWait()
-		SDL_SemTryWait()
-		SDL_SemWaitTimeout()
-		SDL_SemPost()
-		SDL_SemValue()
-	The new function prototypes are in SDL_mutex.h
-
-	Added support for asynchronous blitting.  To take advantage of this,
-	you must set the SDL_ASYNCBLIT flag when setting the video mode and
-	creating surfaces that you want accelerated in this way.  You must
-	lock surfaces that have this flag set, and the lock will block until
-	any queued blits have completed.
-
-	Added YUV video overlay support.
-	The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU.
-	This function creates an overlay surface:
-		SDL_CreateYUVOverlay()
-	You must lock and unlock the overlay to get access to the data:
-		SDL_LockYUVOverlay() SDL_UnlockYUVOverlay()
-	You can then display the overlay:
-		SDL_DisplayYUVOverlay()
-	You must free the overlay when you are done using it:
-		SDL_FreeYUVOverlay()
-	See SDL_video.h for the full function prototypes.
-
-	The joystick hat position constants have been changed:
-	Old constant            New constant
-	------------            ------------
-	     0                  SDL_HAT_CENTERED
-	     1                  SDL_HAT_UP
-	     2                  SDL_HAT_RIGHTUP
-	     3                  SDL_HAT_RIGHT
-	     4                  SDL_HAT_RIGHTDOWN
-	     5                  SDL_HAT_DOWN
-	     6                  SDL_HAT_LEFTDOWN
-	     7                  SDL_HAT_LEFT
-	     8                  SDL_HAT_LEFTUP
-	The new constants are bitmasks, so you can check for the
-	individual axes like this:
-		if ( hat_position & SDL_HAT_UP ) {
-		}
-	and you'll catch left-up, up, and right-up.
-
-1.1.2:
-	Added multiple timer support:
-		SDL_AddTimer() and SDL_RemoveTimer()
-
-	SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL.
-
-1.1.0:
-	Added initial OpenGL support.
-	First set GL attributes (such as RGB depth, alpha depth, etc.)
-		SDL_GL_SetAttribute()
-	Then call SDL_SetVideoMode() with the SDL_OPENGL flag.
-	Perform all of your normal GL drawing.
-	Finally swap the buffers with the new SDL function:
-		SDL_GL_SwapBuffers()
-	See the new 'testgl' test program for an example of using GL with SDL.
-
-	You can load GL extension functions by using the function:
-		SDL_GL_LoadProcAddress()
-
-	Added functions to initialize and cleanup specific SDL subsystems:
-		SDL_InitSubSystem() and SDL_QuitSubSystem()
-
-	Added user-defined event type:
-		typedef struct {
-        		Uint8 type;
-        		int code;
-        		void *data1;
-        		void *data2;
-		} SDL_UserEvent;
-	This structure is in the "user" member of an SDL_Event.
-
-	Added a function to push events into the event queue:
-		SDL_PushEvent()
-
-	Example of using the new SDL user-defined events:
-	{
-		SDL_Event event;
-
-		event.type = SDL_USEREVENT;
-		event.user.code = my_event_code;
-		event.user.data1 = significant_data;
-		event.user.data2 = 0;
-		SDL_PushEvent(&event);
-	}
-
-	Added a function to get mouse deltas since last query:
-		SDL_GetRelativeMouseState()
-
-	Added a boolean datatype to SDL_types.h:
-		SDL_bool = { SDL_TRUE, SDL_FALSE }
-
-	Added a function to get the current audio status:
-		SDL_GetAudioState();
-	It returns one of:
-		SDL_AUDIO_STOPPED,
-		SDL_AUDIO_PLAYING,
-		SDL_AUDIO_PAUSED
-
-	Added an AAlib driver (ASCII Art) - by Stephane Peter.
-
-1.0.6:
-	The input grab state is reset after each call to SDL_SetVideoMode().
-	The input is grabbed by default in fullscreen mode, and ungrabbed in
-	windowed mode.  If you want to set input grab to a particular value,
-	you should set it after each call to SDL_SetVideoMode().
-
-1.0.5:
-	Exposed SDL_AudioInit(), SDL_VideoInit()
-	Added SDL_AudioDriverName() and SDL_VideoDriverName()
-
-	Added new window manager function:
-		SDL_WM_ToggleFullScreen()
-	This is currently implemented only on Linux
-
-	The ALT-ENTER code has been removed - it's not appropriate for a
-	lib to bind keys when they aren't even emergency escape sequences.
-
-	ALT-ENTER functionality can be implemented with the following code:
-
-	int Handle_AltEnter(const SDL_Event *event)
-	{
-	    if ( event->type == SDL_KEYDOWN ) {
-	        if ( (event->key.keysym.sym == SDLK_RETURN) &&
-	             (event->key.keysym.mod & KMOD_ALT) ) {   
-	                SDL_WM_ToggleFullScreen(SDL_GetVideoSurface());
-	                return(0);
-	        }
-	    }
-	    return(1);
-	}
-	SDL_SetEventFilter(Handle_AltEnter);
-
-1.0.3:
-	Under X11, if you grab the input and hide the mouse cursor,
-	the mouse will go into a "relative motion" mode where you
-	will always get relative motion events no matter how far in
-	each direction you move the mouse - relative motion is not
-	bounded by the edges of the window (though the absolute values
-	of the mouse positions are clamped by the size of the window).
-	The SVGAlib, framebuffer console, and DirectInput drivers all
-	have this behavior naturally, and the GDI and BWindow drivers
-	never go into "relative motion" mode.
-
-1.0.2:
-	Added a function to enable keyboard repeat:
-		SDL_EnableKeyRepeat()
-
-	Added a function to grab the mouse and keyboard input
-		SDL_WM_GrabInput()
-
-	Added a function to iconify the window.
-		SDL_WM_IconifyWindow()
-	If this function succeeds, the application will receive an event
-	signaling SDL_APPACTIVE event 
-
-1.0.1:
-	Added constants to SDL_audio.h for 16-bit native byte ordering:
-		AUDIO_U16SYS, AUDIO_S16SYS
-
-1.0.0:
-	New public release
-
-Version 0.11:
-
-0.11.5:
-	A new function SDL_GetVideoSurface() has been added, and returns
-	a pointer to the current display surface.
-
-	SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and
-	a new function SDL_CreateRGBSurfaceFrom() has been added to allow
-	creating an SDL surface from an existing pixel data buffer.
-
-	Added SDL_GetRGB() to the headers and documentation.
-
-0.11.4:
-	SDL_SetLibraryPath() is no longer meaningful, and has been removed.
-
-0.11.3:
-	A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from
-	installing fatal signal handlers on operating systems that support
-	them.
-
-Version 0.9:
-
-0.9.15:
-	SDL_CreateColorCursor() has been removed.  Color cursors should
-	be implemented as sprites, blitted by the application when the
-	cursor moves.  To get smooth color cursor updates when the app
-	is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init().  This
-	allows you to handle the mouse motion in another thread from an
-	event filter function, but is currently only supported by Linux
-	and BeOS.  Note that you'll have to protect the display surface
-	from multi-threaded access by using mutexes if you do this.
-
-	Thread-safe surface support has been removed from SDL.
-	This makes blitting somewhat faster, by removing SDL_MiddleBlit().
-	Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead.
-	You can make your surfaces thread-safe by allocating your own
-	mutex and making lock/unlock calls around accesses to your surface.
-
-0.9.14:
-	SDL_GetMouseState() now takes pointers to int rather than Uint16.
-
-	If you set the SDL_WINDOWID environment variable under UNIX X11,
-	SDL will use that as the main window instead of creating it's own.
-	This is an unsupported extension to SDL, and not portable at all.
-
-0.9.13:
-	Added a function SDL_SetLibraryPath() which can be used to specify
-	the directory containing the SDL dynamic libraries.  This is useful
-	for commercial applications which ship with particular versions
-	of the libraries, and for security on multi-user systems.
-	If this function is not used, the default system directories are 
-	searched using the native dynamic object loading mechanism.
-
-	In order to support C linkage under Visual C++, you must declare
-	main() without any return type:
-		main(int argc, char *argv[]) {
-			/* Do the program... */
-			return(0);
-		}
-	C++ programs should also return a value if compiled under VC++.
-
-	The blit_endian member of the SDL_VideoInfo struct has been removed.
-
-	SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there
-	is now no longer any function to translate a keysym to a character.
-
-	The SDL_keysym structure has been extended with a 'scancode' and
-	'unicode' member.  The 'scancode' is a hardware specific scancode
-	for the key that was pressed, and may be 0.  The 'unicode' member
-	is a 16-bit UNICODE translation of the key that was pressed along
-	with any modifiers or compose keys that have been pressed.
-	If no UNICODE translation exists for the key, 'unicode' will be 0.
-
-	Added a function SDL_EnableUNICODE() to enable/disable UNICODE
-	translation of character keypresses.  Translation defaults off.
-
-	To convert existing code to use the new API, change code which
-	uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(),
-	and change code which uses it to get the ASCII value of a sym to
-	use the 'unicode' member of the event keysym.
-
-0.9.12:
-	There is partial support for 64-bit datatypes.  I don't recommend 
-	you use this if you have a choice, because 64-bit datatypes are not
-	supported on many platforms.  On platforms for which it is supported,
-	the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and
-	you can use the Uint64 and Sint64 datatypes.
-
-	Added functions to SDL_endian.h to support 64-bit datatypes:
-	    SDL_SwapLE64(), SDL_SwapBE64(),
-	    SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64()
-
-	A new member "len_ratio" has been added to the SDL_AudioCVT structure,
-	and allows you to determine either the original buffer length or the
-	converted buffer length, given the other.
-
-	A new function SDL_FreeWAV() has been added to the API to free data
-	allocated by SDL_LoadWAV_RW().  This is necessary under Win32 since
-	the gcc compiled DLL uses a different heap than VC++ compiled apps.
-
-	SDL now has initial support for international keyboards using the
-	Latin character set.
-	If a particular mapping is desired, you can set the DEFAULT_KEYBOARD
-	compile-time variable, or you can set the environment variable 
-	"SDL_KEYBOARD" to a string identifying the keyboard mapping you desire.
-	The valid values for these variables can be found in SDL_keyboard.c
-
-	Full support for German and French keyboards under X11 is implemented.
-
-0.9.11:
-	The THREADED_EVENTS compile-time define has been replaced with the
-	SDL_INIT_EVENTTHREAD flag.  If this flag is passed to SDL_Init(),
-	SDL will create a separate thread to perform input event handling.
-	If this flag is passed to SDL_Init(), and the OS doesn't support 
-	event handling in a separate thread, SDL_Init() will fail.
-	Be sure to add calls to SDL_Delay() in your main thread to allow
-	the OS to schedule your event thread, or it may starve, leading
-	to slow event delivery and/or dropped events.
-	Currently MacOS and Win32 do not support this flag, while BeOS 
-	and Linux do support it.  I recommend that your application only
-	use this flag if absolutely necessary.
-
-	The SDL thread function passed to SDL_CreateThread() now returns a
-	status.  This status can be retrieved by passing a non-NULL pointer
-	as the 'status' argument to SDL_WaitThread().
-
-	The volume parameter to SDL_MixAudio() has been increased in range
-	from (0-8) to (0-128)
-
-	SDL now has a data source abstraction which can encompass a file,
-	an area of memory, or any custom object you can envision.  It uses
-	these abstractions, SDL_RWops, in the endian read/write functions,
-	and the built-in WAV and BMP file loaders.  This means you can load
-	WAV chunks from memory mapped files, compressed archives, network
-	pipes, or anything else that has a data read abstraction.
-
-	There are three built-in data source abstractions:
-	    SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem()
-	along with a generic data source allocation function:
-	    SDL_AllocRW()
-	These data sources can be used like stdio file pointers with the
-	following convenience functions:
-	    SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose()
-	These functions are defined in the new header file "SDL_rwops.h"
-
-	The endian swapping functions have been turned into macros for speed
-	and SDL_CalculateEndian() has been removed.  SDL_endian.h now defines
-	SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on
-	the endianness of the host system.
-
-	The endian read/write functions now take an SDL_RWops pointer
-	instead of a stdio FILE pointer, to support the new data source
-	abstraction.
-
-	The SDL_*LoadWAV() functions have been replaced with a single
-	SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's
-	first parameter, and a flag whether or not to automatically 
-	free it as the second parameter.  SDL_LoadWAV() is a macro for
-	backward compatibility and convenience:
-	    SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...);
-
-	The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced
-	with a single function that takes a SDL_RWops pointer as it's
-	first parameter, and a flag whether or not to automatically 
-	free it as the second parameter.  SDL_LoadBMP() and SDL_SaveBMP()
-	are macros for backward compatibility and convenience:
-	    SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...);
-	    SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...);
-	Note that these functions use SDL_RWseek() extensively, and should
-	not be used on pipes or other non-seekable data sources.
-
-0.9.10:
-	The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been 
-	extended to support multiple types of display drivers, as well as
-        safe access to the X11 display when THREADED_EVENTS is enabled.
-        The new structures are documented in the SDL_syswm.h header file.
-
-	Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard
-	should now work properly, as well as the "Windows" keys on US
-	keyboards.
-
-	The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab
-	instead of trying to open each block device on the system.
-	The CD must be listed in /etc/fstab as using the iso9660 filesystem.
-
-	On Linux, if you define THREADED_EVENTS at compile time, a separate
-	thread will be spawned to gather X events asynchronously from the
-	graphics updates.  This hasn't been extensively tested, but it does
-	provide a means of handling keyboard and mouse input in a separate
-	thread from the graphics thread.  (This is now enabled by default.)
-
-	A special access function SDL_PeepEvents() allows you to manipulate
-	the event queue in a thread-safe manner, including peeking at events,
-	removing events of a specified type, and adding new events of arbitrary
-	type to the queue (use the new 'user' member of the SDL_Event type).
-
-	If you use SDL_PeepEvents() to gather events, then the main graphics
-	thread needs to call SDL_PumpEvents() periodically to drive the event
-	loop and generate input events.  This is not necessary if SDL has been 
-	compiled with THREADED_EVENTS defined, but doesn't hurt.
-
-	A new function SDL_ThreadID() returns the identifier associated with
-	the current thread.
-
-0.9.9:
-	The AUDIO_STEREO format flag has been replaced with a new 'channels'
-	member of the SDL_AudioSpec structure.  The channels are 1 for mono
-	audio, and 2 for stereo audio.  In the future more channels may be
-	supported for 3D surround sound.
-
-	The SDL_MixAudio() function now takes an additional volume parameter,
-	which should be set to SDL_MIX_MAXVOLUME for compatibility with the
-	original function.
-
-	The CD-ROM functions which take a 'cdrom' parameter can now be
-	passed NULL, and will act on the last successfully opened CD-ROM.
-
-0.9.8:
-	No changes, bugfixes only.
-	
-0.9.7:
-	No changes, bugfixes only.
-	
-0.9.6:
-	Added a fast rectangle fill function: SDL_FillRect()
-
-	Addition of a useful function for getting info on the video hardware:
-	    const SDL_VideoInfo *SDL_GetVideoInfo(void)
-        This function replaces SDL_GetDisplayFormat().
-
-	Initial support for double-buffering:
-	  Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode()
-	  Update the screen with a new function: SDL_Flip()
-
-	SDL_AllocSurface() takes two new flags:
-	SDL_SRCCOLORKEY means that the surface will be used for colorkey blits
-	  and if the hardware supports hardware acceleration of colorkey blits
-	  between two surfaces in video memory, to place the surface in video
-	  memory if possible, otherwise it will be placed in system memory.
-	SDL_SRCALPHA means that the surface will be used for alpha blits and
-	  if the hardware supports hardware acceleration of alpha blits between
-	  two surfaces in video memory, to place the surface in video memory
-	  if possible, otherwise it will be placed in system memory.
-	SDL_HWSURFACE now means that the surface will be created with the 
-	  same format as the display surface, since having surfaces in video
-	  memory is only useful for fast blitting to the screen, and you can't
-	  blit surfaces with different surface formats in video memory.
-
-0.9.5:
-	You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume
-	that the icon consists of the entire image.
-
-	SDL_LowerBlit() is back -- but don't use it on the display surface.
-	It is exactly the same as SDL_MiddleBlit(), but doesn't check for
-	thread safety.
-
-	Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take
-	a FILE pointer instead of a file name.
-
-	Added CD-ROM audio control API:
-	    SDL_CDNumDrives()
-	    SDL_CDName()
-	    SDL_CDOpen()
-	    SDL_CDStatus()
-	    SDL_CDPlayTracks()
-	    SDL_CDPlay()
-	    SDL_CDPause()
-	    SDL_CDResume()
-	    SDL_CDStop()
-	    SDL_CDEject()
-	    SDL_CDClose()

-SDL 1.2.10 is a major release, featuring a revamp of the build system and many API improvements and bug fixes.
-</P>
-<H3> API enhancements </H3>
-<UL>
-<LI>
-	If SDL_OpenAudio() is passed zero for the desired format
-	fields, the following environment variables will be used
-	to fill them in:
-<pre><code>
-		SDL_AUDIO_FREQUENCY
-		SDL_AUDIO_FORMAT
-		SDL_AUDIO_CHANNELS

-</code></pre>
-	If an environment variable is not specified, it will be set
-	to a reasonable default value.
-<LI>
-	SDL_SetVideoMode() now accepts 0 for width or height and will use
-	the current video mode (or the desktop mode if no mode has been set.)
-<LI>
-	Added current_w and current_h to the SDL_VideoInfo structure,
-	which is set to the desktop resolution during video intialization,
-	and then set to the current resolution when a video mode is set.
-<LI>
-	SDL_GL_LoadLibrary() will load the system default OpenGL library
-	if it is passed NULL as a parameter.
-<LI>
-	Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
-<LI>
-	Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
-<LI>
-	SDL_WM_SetCaption() now officially takes UTF-8 title and icon strings, and displays international characters on supported platforms.
-<LI>
-	Added SDL_GetKeyRepeat() to query the key repeat settings.
-<LI>
-	Added the "dummy" audio driver, which can be used to emulate audio
-	output without a sound card.

-<H3> General Notes </H3>
-
-<BLOCKQUOTE>
-<P>
-	The SDL website now has an <A HREF="http://www.libsdl.org/rss/rss.xml">RSS feed</A>!
-<P>
-	The SDL development source code is now managed with <A HREF="http://www.libsdl.org/svn.php">Subversion</A>.
-<P>
-	SDL now uses the Bugzilla <A HREF="http://bugzilla.libsdl.org/">bug tracking system</A>, hosted by icculus.org.
-<P>
-	SDL is licensed under version 2.1 of the GNU Lesser General Public License.
-<P>
-	The entire build system has been revamped to make it much more portable, including versions of C library functions to make it possible to run SDL on a minimal embedded environment.  See README.Porting in the SDL source distribution for information on how to port SDL to a new platform.
-<P>
-	SDL_opengl.h has been updated with the latest glext.h from <A HREF="http://oss.sgi.com/projects/ogl-sample/registry/">http://oss.sgi.com/projects/ogl-sample/registry/</A>
-<P>
-	Alex Volkov contributed highly optimized RGB <-> RGBA blitters.
-</BLOCKQUOTE>
-
-<H3> Unix Notes </H3>
-
-<BLOCKQUOTE>
-<P>
-	The X11 libraries are dynamically loaded at runtime by default.  This allows the distributed version of SDL to run on systems without X11 libraries installed.
-<P>
-	The XiG XME extension code is now included in the X11 video driver by default.
-<P>
-	XRandR support for video mode switching has been added to the X11 driver, but is disabled because of undesired interactions with window managers.  You can enable this by setting the environment variable SDL_VIDEO_X11_XRANDR to 1.
-<P>
-	Xinerama multi-head displays are properly handled now, and the SDL_VIDEO_FULLSCREEN_HEAD environment variable can be used to select the screen used for fullscreen video modes.  Note that changing the video modes only works on screen 0.
-<P>
-	XVidMode video modes are now sorted so they maintain the refresh rates specified in the X11 configuration file.
-<P>
-	SDL windows are no longer transparent in X11 compositing systems like XGL.
-<P>
-	The mouse is properly released by the X11 video driver if the fullscreen window loses focus.
-<P>
-	The X11 input driver now uses XIM to handle international input.
-<P>
-	The screensaver and DPMS monitor blanking are disabled while SDL games are running under the X11 and DGA video drivers.  This behavior will be formalized and selectable in SDL 1.3.
-<P>
-	Fixed a bug preventing stereo OpenGL contexts from being selected on the X11 driver.
-<P>
-	The DGA video driver now waits for pending blits involving surfaces before they are freed.  This prevents display oddities when using SDL_DisplayFormat() to convert many images.
-<P>
-	The framebuffer console video driver now has a parser for /etc/fb.modes for improved video mode handling.
-<P>
-	The framebuffer console video driver now allows asynchronous VT switching, and restores the full contents of the screen when switched back.
-<P>
-	The framebuffer console now uses CTRL-ALT-FN to switch virtual terminals, to avoid collisions with application key bindings.
-<P>
-	The framebuffer console input driver correctly sets IMPS/2 mode for wheel mice.  It also properly detects when gpm is in IMPS/2 protocol mode, or passing raw protocol from an IMPS/2 mouse.
-<P>
-	The SVGAlib video driver now has support for banked (non-linear) video modes.
-<P>
-	A video driver for OpenBSD on the Sharp Zaurus has been contributed by Staffan Ulfberg.  See the file README.wscons in the SDL source distribution for details.
-<P>
-	Many patches have been incorporated from *BSD ports.
-</BLOCKQUOTE>
-
-<H3> Windows Notes </H3>
-
-<BLOCKQUOTE>
-<P>
-	The "windib" video driver is the default now, to prevent problems with certain laptops, 64-bit Windows, and Windows Vista.  The DirectX driver is still available, and can be selected by setting the environment variable SDL_VIDEODRIVER to "directx".
-<P>
-	SDL has been ported to 64-bit Windows.
-<P>
-	Dmitry Yakimov contributed a GAPI video driver for Windows CE.
-<P>
-	The default fullscreen refresh rate has been increased to match the desktop refresh rate, when using equivalent resolutions.  A full API for querying and selecting refresh rates is planned for SDL 1.3.
-<P>
-	Dialog boxes are now shown when SDL is in windowed OpenGL mode.
-<P>
-	The SDL window is recreated when necessary to maintain OpenGL context attributes, when switching between windowed and fullscreen modes.
-<P>
-	An SDL_VIDEORESIZE event is properly sent when the SDL window is maximized and restored.
-<P>
-	Window positions are retained when switching between fullscreen and windowed modes.
-<P>
-	ToUnicode() is used, when available, for improved handling of international keyboard input.
-<P>
-	The PrtScrn is now treated normally with both key down and key up events.
-<P>
-	Pressing ALT-F4 now delivers an SDL_QUIT event to SDL applications.
-<P>
-	Joystick names are now correct for joysticks which have been unplugged and then plugged back in since booting.
-<P>
-	An MCI error when playing the last track on a CD-ROM has been fixed.
-<P>
-	OpenWatcom projects for building SDL have been provided by Marc Peter.
-</BLOCKQUOTE>
-
-<H3> Mac OS X Notes </H3>
-
-<BLOCKQUOTE>
-<P>
-	SDL now supports building Universal binaries, both through Xcode projects and when using configure/make.  See README.MacOSX in the SDL source archive for details.
-<P>
-	The X11 video driver with GLX support can be built on Mac OS X, if the X11 development SDK is installed.
-<P>
-	Transitions between fullscreen resolutions and windowed mode now use a much faster asynchronous fade to hide desktop flicker.
-<P>
-	Icons set with SDL_WM_SetIcon() now have the proper colors on Intel Macs.
-</BLOCKQUOTE>
-
-<H3> OS/2 Notes </H3>
-
-<BLOCKQUOTE>
-<P>
-	Projects for building SDL on OS/2 with OpenWatcom have been contributed by Doodle.  See the file README.OS2 in the SDL source distribution for details.

->Sound on the computer is translated from waves that you hear into a series of 
-values, or samples, each representing the amplitude of the wave.  When these
-samples are sent in a stream to a sound card, an approximation of the original
-wave can be recreated.  The more bits used to represent the amplitude, and the
-greater frequency these samples are gathered, the closer the approximated
-sound is to the original, and the better the quality of sound.</P
-><P
->This library supports both 8 and 16 bit signed and unsigned sound samples,
-at frequencies ranging from 11025 Hz to 44100 Hz, depending on the 
-underlying hardware.  If the hardware doesn't support the desired audio
-format or frequency, it can be emulated if desired (See

->Event handling allows your application to receive input from the user. Event handling is initalised (along with video) with a call to:
-<PRE
-CLASS="PROGRAMLISTING"
->SDL_Init(SDL_INIT_VIDEO);</PRE
->
-Internally, SDL stores all the events waiting to be handled in an event queue. Using functions like <A
-HREF="sdlpollevent.html"
-><TT
-CLASS="FUNCTION"
->SDL_PollEvent</TT
-></A
-> and <A
-HREF="sdlpeepevents.html"
-><TT

-><P
->The key to event handling in SDL is the <A
-HREF="sdlevent.html"
-><SPAN
-CLASS="STRUCTNAME"
->SDL_Event</SPAN
-></A
-> union. The event queue itself is composed of a series of <SPAN
-CLASS="STRUCTNAME"
->SDL_Event</SPAN
-> unions, one for each waiting event. <SPAN
-CLASS="STRUCTNAME"
->SDL_Event</SPAN
-> unions are read from the queue with the <TT
-CLASS="FUNCTION"
->SDL_PollEvent</TT
-> function and it is then up to the application to process the information stored with them.</P

->Initializing SDL</H1
-><P
->SDL is composed of eight subsystems - Audio, CDROM, Event Handling, File I/O, Joystick Handling, Threading, Timers and Video. Before you can use any of these subsystems they must be initialized by calling <A
-HREF="sdlinit.html"
-><TT
-CLASS="FUNCTION"
->SDL_Init</TT
-></A
-> (or <A
-HREF="sdlinitsubsystem.html"
-><TT
-CLASS="FUNCTION"
->SDL_InitSubSystem</TT
-></A
->). <TT
-CLASS="FUNCTION"
->SDL_Init</TT
-> must be called before any other SDL function. It automatically initializes the Event Handling, File I/O and Threading subsystems and it takes a parameter specifying which other subsystems to initialize. So, to initialize the default subsystems and the Video subsystems you would call:
-<PRE
-CLASS="PROGRAMLISTING"
->    SDL_Init ( SDL_INIT_VIDEO );</PRE
->
-To initialize the default subsystems, the Video subsystem and the Timers subsystem you would call:
-<PRE
-CLASS="PROGRAMLISTING"
->    SDL_Init ( SDL_INIT_VIDEO | SDL_INIT_TIMER );</PRE
-></P
-><P
-><TT
-CLASS="FUNCTION"
->SDL_Init</TT
-> is complemented by <A
-HREF="sdlquit.html"
-><TT
-CLASS="FUNCTION"
->SDL_Quit</TT
-></A
-> (and <A
-HREF="sdlquitsubsystem.html"
-><TT
-CLASS="FUNCTION"
->SDL_QuitSubSystem</TT
-></A
->). <TT
-CLASS="FUNCTION"
->SDL_Quit</TT
-> shuts down all subsystems, including the default ones. It should always be called before a SDL application exits.</P
-><P
->With <TT
-CLASS="FUNCTION"
->SDL_Init</TT
-> and <TT
-CLASS="FUNCTION"
->SDL_Quit</TT
-> firmly embedded in your programmers toolkit you can write your first and most basic SDL application. However, we must be prepare to handle errors. Many SDL functions return a value and indicates whether the function has succeeded or failed, <TT
-CLASS="FUNCTION"
->SDL_Init</TT
->, for instance, returns -1 if it could not initialize a subsystem. SDL provides a useful facility that allows you to determine exactly what the problem was, every time an error occurs within SDL an error message is stored which can be retrieved using <TT
-CLASS="FUNCTION"
->SDL_GetError</TT
->. Use this often, you can never know too much about an error.</P

->Querying</H2

->If we have reached this point then we can safely assume that the SDL library has been initialized and that the Joystick subsystem is active. We can now call some video and/or sound functions to get things going before we need the joystick. Eventually we have to make sure that there is actually a joystick to work with. It's wise to always check even if you know a joystick will be present on the system because it can also help detect when the joystick is unplugged. The function used to check for joysticks is <A
-HREF="sdlnumjoysticks.html"
-><TT
-CLASS="FUNCTION"
->SDL_NumJoysticks</TT
-></A
->.</P
-><P
->This function simply returns the number of joysticks available on the system. If it is at least one then we are in good shape. The next step is to determine which joystick the user wants to use. If the number of joysticks available is only one then it is safe to assume that one joystick is the one the user wants to use. SDL has a function to get the name of the joysticks as assigned by the operations system and that function is <A
-HREF="sdljoystickname.html"
-><TT
-CLASS="FUNCTION"
->SDL_JoystickName</TT
-></A
->.  The joystick is specified by an index where 0 is the first joystick and the last joystick is the number returned by <TT

-></A
-> with the <TT
-CLASS="LITERAL"

-HREF="sdljoystickopen.html"
-><TT

->    SDL_Joystick *joystick;

-    SDL_JoystickEventState(SDL_ENABLE);
-    joystick = SDL_JoystickOpen(0);</PRE
-></DIV
-><P
->If we wanted to receive events for other joysticks we would open them with calls to <TT
-CLASS="FUNCTION"
->SDL_JoystickOpen</TT
-> just like we opened joystick 0, except we would store the <SPAN
-CLASS="STRUCTNAME"
->SDL_Joystick</SPAN
-> structure they return in a different pointer.  We only need the joystick pointer when we are querying the joysticks or when we are closing the joystick.</P
-><P
->Up to this point all the code we have is used just to initialize the joysticks in order to read values at run time. All we need now is an event loop, which is something that all SDL programs should have anyway to receive the systems quit events. We must now add code to check the event loop for at least some of the above mentioned events. Let's assume our event loop looks like this:
-<PRE
-CLASS="PROGRAMLISTING"
->    SDL_Event event;
-    /* Other initializtion code goes here */   
-
-    /* Start main game loop here */
-
-    while(SDL_PollEvent(&#38;event))
-    {  
-        switch(event.type)
-        {  
-            case SDL_KEYDOWN:
-            /* handle keyboard stuff here */				
-            break;
-
-            case SDL_QUIT:
-            /* Set whatever flags are necessary to */
-            /* end the main game loop here */
-            break;
-        }
-    }
-
-    /* End loop here */</PRE
->
-To handle Joystick events we merely add cases for them, first we'll add axis handling code. Axis checks can get kinda of tricky because alot of the joystick events received are junk. Joystick axis have a tendency to vary just a little between polling due to the way they are designed. To compensate for this you have to set a threshold for changes and ignore the events that have'nt exceeded the threshold. 10% is usually a good threshold value.  This sounds a lot more complicated than it is. Here is the Axis event handler:</P

-    {
-      /* code goes here */
-    }
-    break;</PRE
-></DIV
-><P
->Another trick with axis events is that up-down and left-right movement are two different sets of axes. The most important axis is axis 0 (left-right) and axis 1 (up-down).  To handle them seperatly in the code we do the following:</P
-><DIV
-CLASS="EXAMPLE"

-><B
->Example 3-5. More Joystick Axis Events</B

-    {
-        if( event.jaxis.axis == 0) 
-        {
-            /* Left-right movement code goes here */
-        }
-
-        if( event.jaxis.axis == 1) 
-        {
-            /* Up-Down movement code goes here */
-        }
-    }
-    break;</PRE
-></DIV
-><P
->Ideally the code here should use <TT
-CLASS="STRUCTFIELD"
-><I
->event.jaxis.value</I
-></TT
-> to scale something. For example lets assume you are using the joystick to control the movement of a spaceship. If the user is using an analog joystick and they push the stick a little bit they expect to move less than if they pushed it a lot. Designing your code for this situation is preferred because it makes the experience for users of analog controls better and remains the same for users of digital controls.</P
-><P
->If your joystick has any additional axis then they may be used for other sticks or throttle controls and those axis return values too just with different <TT
-CLASS="STRUCTFIELD"
-><I
->event.jaxis.axis</I
-></TT
-> values.</P
-><P
->Button handling is simple compared to the axis checking.</P

-    {
-        /* code goes here */
-    }
-    break;</PRE
-></DIV
-><P
->Button checks are simpler than axis checks because a button can only be pressed or not pressed.  The <TT
-CLASS="LITERAL"
->SDL_JOYBUTTONDOWN</TT
-> event is triggered when a button is pressed and the <TT
-CLASS="LITERAL"
->SDL_JOYBUTTONUP</TT
-> event is fired when a button is released. We do have to know what button was pressed though, that is done by reading the <TT
-CLASS="STRUCTFIELD"
-><I
->event.jbutton.button</I
-></TT
-> field.</P
-><P
->Lastly when we are through using our joysticks we should close them with a call to <A
-HREF="sdljoystickclose.html"
-><TT
-CLASS="FUNCTION"
->SDL_JoystickClose</TT
-></A
->. To close our opened joystick 0 we would do this at the end of our program:

->Advanced Joystick Functions</H2
-><P
->That takes care of the controls that you can count on being on every joystick under the sun, but there are a few extra things that SDL can support.  Joyballs are next on our list, they are alot like axis with a few minor differences.  Joyballs store relative changes unlike the the absolute postion stored in a axis event. Also one trackball event contains both the change in x and they change in y.  Our case for it is as follows:</P

-><P
->The above checks the first joyball on the joystick. The change in position will be stored in <TT

-><I

-> and <TT
-CLASS="STRUCTFIELD"
-><I
->event.jball.yrel</I

->Finally we have the hat event. Hats report only the direction they are pushed in. We check hat's position with the bitmasks:

-At first glance you may think this is a perfectly reasonable piece of code for the task, but it isn't. Like I said keyboard events only occur when a key changes state, so the user would have to press and release the left cursor key 100 times to move the alien 100 pixels to the left.</P
-><P
->To get around this problem we must not use the events to change the position of the alien, we use the events to set flags which are then used in a seperate section of code to move the alien. Something like this:</P

-><P
->The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.</P

->Adds a callback function to be run after the specified number of
-milliseconds has elapsed. The callback function is passed the current
-timer interval and the user supplied parameter from the
-<TT
-CLASS="FUNCTION"
->SDL_AddTimer</TT
-> call and returns the next timer
-interval. If the returned value from the callback is the same as the one
-passed in, the periodic alarm continues, otherwise a new alarm is
-scheduled.</P
-><P
->To cancel a currently running timer call
-<A
-HREF="sdlremovetimer.html"
->SDL_RemoveTimer</A
-> with the
-timer ID returned from
-<TT
-CLASS="FUNCTION"
->SDL_AddTimer</TT
->.</P
-><P
->The timer callback function may run in a different thread than your
-main program, and so shouldn't call any functions from within itself.
-You may always call <A
-HREF="sdlpushevent.html"
->SDL_PushEvent</A
->, however.</P
-><P
->The granularity of the timer is platform-dependent, but you should count
-on it being at least 10 ms as this is the most common number.
-This means that if
-you request a 16 ms timer, your callback will run approximately 20 ms
-later on an unloaded system.  If you wanted to set a flag signaling
-a frame update at 30 frames per second (every 33 ms), you might set a
-timer for 30 ms (see example below).
-
-If you use this function, you need to pass <TT
-CLASS="LITERAL"

->
-to <A

-The <TT

-CLASS="STRUCTNAME"
->SDL_Event</SPAN
-> structure that is to be filled with event information. We know that if <TT
-CLASS="FUNCTION"
->SDL_PollEvent</TT
-> removes an event from the queue then the event information will be placed in our <SPAN
-CLASS="STRUCTNAME"
->test_event</SPAN
-> structure, but we also know that the <SPAN

-> of event will be placed in the <TT
-CLASS="STRUCTFIELD"
-><I
->type</I
-></TT
-> member of <SPAN
-CLASS="STRUCTNAME"
->test_event</SPAN
->. So to handle each event <TT
-CLASS="STRUCTFIELD"
-><I
->type</I
-></TT
-> seperately we use a <TT

-<PRE
-CLASS="PROGRAMLISTING"

-We need to know what kind of events we're looking for <SPAN

-></SPAN
-> the event <TT
-CLASS="STRUCTFIELD"
-><I

-CLASS="LITERAL"
->SDL_MOUSEMOTION</TT

-HREF="sdlmousemotionevent.html"
->more</A

-> structure which is the <TT
-CLASS="STRUCTFIELD"
-><I
->motion</I
-></TT
-> member of <SPAN
-CLASS="STRUCTNAME"
->SDL_Event</SPAN

-CLASS="LITERAL"
->SDL_MOUSEMOTION</TT
-> event <TT
-CLASS="STRUCTFIELD"
-><I
->type</I
-></TT
-> within our <TT
-CLASS="FUNCTION"
->switch</TT

-<PRE

-All we need do now is read the information out of the <TT

->The <TT

-><I
->sym</I
-></TT
-> field is extremely useful. It is the SDL-defined value of the key (see <A
-HREF="sdlkey.html"
->SDL Key Syms</A
->. This field is very useful when you are checking for certain key presses, like so:
-<PRE
-CLASS="PROGRAMLISTING"
->.
-.
-while(SDL_PollEvent(&#38;event)){
-  switch(event.type){
-    case SDL_KEYDOWN:
-      if(event.key.keysym.sym==SDLK_LEFT)
-        move_left();
-      break;

-}
-.

-<TT
-CLASS="STRUCTFIELD"
-><I

-></TT

-HREF="sdlgetmodstate.html"
-><TT
-CLASS="FUNCTION"
->SDL_GetModState</TT
-></A
->. The <TT
-CLASS="STRUCTFIELD"
-><I
->unicode</I
-></TT
-> is only used when UNICODE translation is enabled with <A
-HREF="sdlenableunicode.html"
-><TT
-CLASS="FUNCTION"
->SDL_EnableUNICODE</TT
-></A
->. If <TT
-CLASS="STRUCTFIELD"
-><I
->unicode</I
-></TT
-> is non-zero then this a the UNICODE character corresponding to the keypress. If the high 9 bits of the character are 0, then this maps to the equivalent ASCII character:
-<PRE
-CLASS="PROGRAMLISTING"
->char ch;
-if ( (keysym.unicode &#38; 0xFF80) == 0 ) {
-  ch = keysym.unicode &#38; 0x7F;
-}
-else {
-  printf("An International Character.\n");
-}</PRE
->
-UNICODE translation does have a slight overhead so don't enable it unless its needed.</P

->The desired size of the audio buffer in samples. This number should be a power of two, and may be adjusted by the audio driver to a value more suitable for the hardware.  Good values seem to range between 512 and 8192 inclusive, depending on the application and CPU speed.  Smaller values yield faster response time, but can lead to underflow if the application is doing heavy processing and cannot fill the audio buffer in time.

->This function sets up a filter to process all events before they are posted

-is prototyped as:
-<PRE
-CLASS="PROGRAMLISTING"
->typedef int (*SDL_EventFilter)(const SDL_Event *event);</PRE
->
-If the filter returns <SPAN
-CLASS="RETURNVALUE"
->1</SPAN
->, then the event will be 
-added to the internal queue.  If it returns <SPAN
-CLASS="RETURNVALUE"
->0</SPAN
->, 
-then the event will be dropped from the queue.  This allows selective
-filtering of dynamically.</P
-><P
->There is one caveat when dealing with the <TT
-CLASS="LITERAL"
->SDL_QUITEVENT</TT
-> event type.  The
-event filter is only called when the window manager desires to close the
-application window.  If the event filter returns 1, then the window will
-be closed, otherwise the window will remain open if possible.
-If the quit event is generated by an interrupt signal, it will bypass the
-internal queue and be delivered to the application at the next event poll.</P

->SDL presents a very simple interface to the display framebuffer.  The
-framebuffer is represented as an offscreen surface to which you can write
-directly.  If you want the screen to show what you have written, call the <A
-HREF="sdlupdaterects.html"
->update</A
-> function which will
-guarantee that the desired portion of the screen is updated.</P
-><P
->Before you call any of the SDL video functions, you must first call
-<SPAN
-CLASS="TOKEN"
->SDL_Init(SDL_INIT_VIDEO)</SPAN
->, which initializes the video
-and events in the SDL library.  Check the return code, which should be
-<SPAN
-CLASS="RETURNVALUE"
->0</SPAN
->, to see if there were any errors in starting up.</P
-><P
->If you use both sound and video in your application, you need to call
-<SPAN
-CLASS="TOKEN"
->SDL_Init(SDL_INIT_AUDIO | SDL_INIT_VIDEO)</SPAN
-> before opening the
-sound device, otherwise under Win32 DirectX, you won't be able to set
-full-screen display modes.</P
-><P
->After you have initialized the library, you can start up the video display in a
-number of ways.  The easiest way is to pick a common screen resolution and
-depth and just initialize the video, checking for errors.  You will probably
-get what you want, but SDL may be emulating your requested mode and converting
-the display on update.  The best way is to
-<A
-HREF="sdlgetvideoinfo.html"
->query</A
->, for the best
-video mode closest to the desired one, and then
-<A
-HREF="sdldisplayformat.html"
->convert</A
->
-your images to that pixel format.</P
-><P
->SDL currently supports any bit depth &gt;= 8 bits per pixel.  8 bpp formats are
-considered 8-bit palettized modes, while 12, 15, 16, 24, and 32 bits per pixel
-are considered "packed pixel" modes, meaning each pixel contains the RGB color
-components packed in the bits of the pixel.</P
-><P
->After you have initialized your video mode, you can take the surface that was
-returned, and write to it like any other framebuffer, calling the update
-routine as you go.</P
-><P
->When you have finished your video access and are ready to quit your
-application, you should call "<SPAN
-CLASS="TOKEN"
->SDL_Quit()</SPAN
->" to shutdown the
-video and events.</P

-This library is designed to make it easy to write games that run on many
-different platforms using the various native high-performance media interfaces,
-(for video, audio, etc) and presenting a single source-code level API to
-your application.  This is a fairly low level API, but using this, completely
-portable applications can be written with a great deal of flexibility.

+FastLZ - lightning-fast lossless compression library
+
+Author: Ariya Hidayat
+Official website: http://www.fastlz.org
+
+FastLZ is distributed using the MIT license, see file LICENSE
+for details.
+
+FastLZ consists of two files: fastlz.h and fastlz.c. Just add these 
+files to your project in order to use FastLZ. For information on 
+compression and decompression routines, see fastlz.h.
+
+A simple file compressor called 6pack is included as an example 
+on how to use FastLZ. The corresponding decompressor is 6unpack. 
+
+To compile using GCC:
+
+  gcc -o 6pack 6pack.c fastlz.c
+  gcc -o 6unpack 6unpack.c fastlz.c
+
+To compile using MinGW:
+
+  mingw32-gcc -o 6pack 6pack.c fastlz.c
+  mingw32-gcc -o 6unpack 6unpack.c fastlz.c
+
+To compile using Microsoft Visual C++:
+
+  cl 6pack.c fastlz.c
+  cl 6unpack.c fastlz.c
+
+To compile using Borland C++:
+
+  bcc32 6pack.c fastlz.c
+  bcc32 6unpack.c fastlz.c
+
+To compile using OpenWatcom C/C++:
+
+  cl386 6pack.c fastlz.c
+  cl386 6unpack.c fastlz.c
+
+To compile using Intel C++ compiler for Windows:
+
+  icl 6pack.c fastlz.c
+  icl 6unpack.c fastlz.c
+
+To compile using Intel C++ compiler for Linux:
+
+  icc -o 6pack 6pack.c fastlz.c
+  icc -o 6unpack 6unpack.c fastlz.c
+
+To compile 6pack using LCC-Win32:
+
+  lc 6pack.c fastlz.c
+  lc 6unpack.c fastlz.c
+
+To compile 6pack using Pelles C:
+
+  pocc 6pack.c
+  pocc 6unpack.c
+  pocc fastlz.c
+  polink 6pack.obj fastlz.obj
+  polink 6unpack.obj fastlz.obj
+
+For speed optimization, always use proper compile flags for optimization options.
+Typical compiler flags are given below:
+
+* GCC (pre 4.2): -march=pentium -O3 -fomit-frame-pointer -mtune=pentium
+* GCC 4.2 or later: -march=pentium -O3 -fomit-frame-pointer -mtune=generic
+* Digital Mars C/C++: -o+all -5
+* Intel C++ (Windows): /O3 /Qipo  
+* Intel C++ (Linux): -O2 -march=pentium -mtune=pentium
+* Borland C++: -O2 -5
+* LCC-Win32: -O
+* Pelles C: /O2
+

    QUICK NOTES:
       Primarily of interest to game developers and other people who can
           avoid problematic images and only need the trivial interface
 
-      JPEG baseline (no JPEG progressive, no oddball channel decimations)
-      PNG 8-bit only
-      BMP non-1bpp, non-RLE
-      TGA (not sure what subset, if a subset)
-      PSD (composited view only, no extra channels)
-      HDR (radiance rgbE format)
-      writes BMP,TGA (define STBI_NO_WRITE to remove code)
-      decoded from memory or through stdio FILE (define STBI_NO_STDIO to remove code)
-      supports installable dequantizing-IDCT, YCbCr-to-RGB conversion (define STBI_SIMD)
-        
-   TODO:
-      stbi_info_*

+//         some glyph)
+//
+//      Glyph index
+//         A font-specific integer ID representing a glyph
+//
+//      Baseline
+//         Glyph shapes are defined relative to a baseline, which is the
+//         bottom of uppercase characters. Characters extend both above
+//         and below the baseline.
+//
+//      Current Point
+//         As you draw text to the screen, you keep track of a "current point"
+//         which is the origin of each character. The current point's vertical
+//         position is the baseline. Even "baked fonts" use this model.
+//
+//      Vertical Font Metrics
+//         The vertical qualities of the font, used to vertically position
+//         and space the characters. See docs for stbtt_GetFontVMetrics.
+//
+//      Font Size in Pixels or Points
+//         The preferred interface for specifying font sizes in stb_truetype
+//         is to specify how tall the font's vertical extent should be in pixels.
+//         If that sounds good enough, skip the next paragraph.
+//
+//         Most font APIs instead use "points", which are a common typographic
+//         measurement for describing font size, defined as 72 points per inch.
+//         stb_truetype provides a point API for compatibility. However, true
+//         "per inch" conventions don't make much sense on computer displays
+//         since they different monitors have different number of pixels per
+//         inch. For example, Windows traditionally uses a convention that
+//         there are 96 pixels per inch, thus making 'inch' measurements have
+//         nothing to do with inches, and thus effectively defining a point to
+//         be 1.333 pixels. Additionally, the TrueType font data provides
+//         an explicit scale factor to scale a given font's glyphs to points,
+//         but the author has observed that this scale factor is often wrong
+//         for non-commercial fonts, thus making fonts scaled in points
+//         according to the TrueType spec incoherently sized in practice.
+//
+// ADVANCED USAGE
+//
+//   Quality:
+//
+//    - Use the functions with Subpixel at the end to allow your characters
+//      to have subpixel positioning. Since the font is anti-aliased, not
+//      hinted, this is very import for quality. (This is not possible with
+//      baked fonts.)
+//
+//    - Kerning is now supported, and if you're supporting subpixel rendering
+//      then kerning is worth using to give your text a polished look.
+//
+//   Performance:
+//
+//    - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
+//      if you don't do this, stb_truetype is forced to do the conversion on
+//      every call.
+//
+//    - There are a lot of memory allocations. We should modify it to take
+//      a temp buffer and allocate from the temp buffer (without freeing),
+//      should help performance a lot.
