dc99ab6b3f [ttGlyphSet] Address review comments 2022-08-15 11:06:51 -06:00
Cosimo Lupo
1dffbae240 support proposed PaintSweepGradient's angles with +1.0 (180°) bias 
In the upcoming draft of COLR spec, PaintSweepGradient's startAngle/endAngle are encoded with a +1.0 bias to allow for representation of a full +360° positive angle. Normal F2Dot14-fraction-of-half-circle angles can only represent angles between -360 <= angle < +360

This is a breaking change and will need to be coordinated with rendering implementations (at least FreeType/Skia).

c63b84db7e Update how table packing falls back to fontTools from harfbuzz. 
Introduce three compilation modes:
1. Pure python: only uses the existing fonttools packing and overflow resolution.
2. Harfbuzz+python: uses harfbuzz packing and python overflow resolution. Extensions are allowed to be shared.
3. Python fallback: if harfbuzz+python runs out of resolution options, this disables extension sharing and only uses python packing. Once it succeeds control is passed back to the harfbuzz packer to produce the final packing with extension sharing enabled.

0e6a4ec581 [otBase] temporarily disable extension sharing during harfbuzz repacking 
If extension sharing is enabled some fonts may fail to repack due to fontTools repacker getting stuck in a unrecoverable error.
