		 * How the CUBE instruction works (guessed mostly, based on DirectX/OpenGL spec):
		   Input: vec4, 3d direction vector (can be unnormalized) + w component (which can be ignored, since it only scales the vector but does not affect the direction)
	
		   First we figure out the major axis (closest axis-aligned vector). There are six possible vectors:
		   +rx	0
		   -rx	1
		   +ry	2
		   -ry	3
		   +rz	4
		   -rz	5
		   The major axis vector is calculated by looking at the largest (absolute) 3d vector component and then setting the other components to 0.0
		   The value that remains in the axis vector is referred to as 'MajorAxis' by the AMD documentation.
		   The S,T coordinates are taken from the other two components.
		   Example:	-0.5,0.2,0.4 -> -rx -> -0.5,0.0,0.0 MajorAxis: -0.5, S: 0.2 T: 0.4

		   The CUBE reduction instruction requires a specific mapping for the input vector:
		   src0 = Rn.zzxy 
		   src1 = Rn.yxzz
		   It's probably related to the way the instruction works internally?
		   If we look at the individual components per ALU unit:
		   z y	-> Compare y/z
		   z x  -> Compare x/z
		   x z  -> Compare x/z
		   y z  -> Compare y/z
