Matthias Clasen 6387004cad [paint] Simplify api 
Drop the hb_paint_context_t struct from the API, and

Matthias Clasen 71bd5a0dfc [paint] Resolve colors 
We don't need to pass the index/alpha pairs to
client callbacks, and can just resolve the colors
internally.

Update test results.
 2022-12-23 13:37:59 -07:00
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 
This will lead to easier implementations.

At the same time, we change the push_clip_glyph
callback to use the font as-is, no unscaling needed.

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

While on a fuzzer-found test case (added) that loop was faster,

Behdad Esfahbod 5a058ba158 [shape-fuzzer] Add commented out more buffer-verify option 
Those currently fail and I've been unable to debug them.

I tried two, passing them to hb-shape doesn't reproduce the failure. :(

Garret Rieger b051f3fa83 [subset] Fix cpal subsetting when there are partial palette overlaps. 
The existing code doesn't correctly handle the case where palettes partially overlap in the color record array. This changes the subsetting to only share entries in the color record array when palettes have the same first color index. Partially overlapping palettes will be converted to disjoint segments in the color record array.

Updates one of the color tests to use multiple palettes.
