Behdad Esfahbod f3985d9482 [paint] Fix drawing non-color glyphs 2022-12-23 13:37:59 -07:00
Matthias Clasen c221933977 [paint] Preserve foreground information 2022-12-23 13:37:59 -07:00
Matthias Clasen 6387004cad [paint] Simplify api
Drop the hb_paint_context_t struct from the API, and
only pass the font where we need it.

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.

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.

Matthias Clasen 686e627bdf [paint] Set up root transform in one place
Instead of spreading this in all the tables,
make hb_paint_funcs_t provide a push/pop_root_transform
that does all the setup.

Behdad Esfahbod b0abbfd868 [font] Centralize glyph-extents scaling
Needs more testing...

Some rounding was removed, namely in cff1 and cff2.

VarC: cast ints (#3934)
msvc is rightfully complaining that the types on the sides of
the ternary are not matching:

```
C:\pango\subprojects\harfbuzz\src\OT\glyf\VarCompositeGlyph.hh(317): error C2446: ':': no conversion from 'const OT::HBUINT16' to 'const OT::HBUINT8'

Garret Rieger 463ae07e99 [subset] In the preprocess subset call always use long loca.
Long loca is needed so that we can store the trimmed glyph bytes to allow us to safely skip trimming in the later subset.
