Behdad Esfahbod c54debc76d [face] Add hb_face_collect_nominal_glyph_mapping
Fixes https://github.com/harfbuzz/harfbuzz/issues/3973
2023-01-05 11:57:48 -07:00
Matthias Clasen 9f3b59fe6b Update expected test results
These need updates, because they record
every callback, and we've changed what
callbacks are happening.

Matthias Clasen 313f74a693 Add a basic test for hb-coretext api
This tests what would be my minimum assumption
about this api. It was written blindly.

Matthias Clasen 9be01b6bff [paint] Pass hb_paint_context_t along
Replace the font argument with a hb_paint_context_t
that carries the font, the palette index and the
foreground color.

The hb_font_paint_glyph() api now takes the palette
index and the foreground color as extra arguments.

Update all callers and regenerate test results.

Matthias Clasen 97224f3b63 [paint] Pass font to all callbacks

Update all callers and expected test results.

Qunxin Liu d5fc4a73c0 [instance] add tests for featureVariations
Also updated the script that is used to generate tests.With fonttools,
we now do instancing first and then subsetting.

With different order of subsetting and instancing operations on the same
VF file, fonttools seems to generate 2 different font files with different
glyph set.
1. do subsetting and then instancing: this seems result in a larger glyph
   set in the font file. Lookups are collected from both retained features
   and all possible alternate featurevariations, this leads to a larger
   glyph set after glyph closurei. And instancer doesn't redo glyph
   closure, it does lookups pruning only.

2. do instancing and then subsetting: lookups are collected from
   features that are replaced already and possible alternate feature
   variations
