A lot of software gets confused when there are named instances that differ
only by opsz. This change removes all "Display" instances from the fvar table
and makes opsz=32 the default, so that software without automatic opsz-to-size
mapping displays the "Display" styles instead of the text styles by default.
This is the same approach taken by Apple San Francisco Pro.
Closes#519
- uses TTC bundle for static fonts (#388)
- second zip archive used for "extras", with individiual static font files
- new help documentation, replacing all .txt files of past distributions
This removes the slant/italic variable axis and breaks up the font in two: roman and italic. This change will allow diverging designs for italic (for example single-storey a). It also addresses the fact that most software, including web browsers, doesn't handle VFs with slnt or ital well.
- UPM is adjusted to 2048
- Additional opsz VF axis (multi master) added which will eventually replace the separate Display family
- New tooling that uses fontmake instead of Inter's own fontbuild toolchain. (The old toolchain is still supported, i.e. `make -f Makefile_v1.make ...`)
