Matthias Clasen 5bd3c07b54 [colr] Don't access baseGlyphList unless v1
This was showing up sporadic crashes due to
invalid reads.

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.

Behdad Esfahbod 6c71c530ca [paint] Rename hb_paint_context_t to hb_ot_paint_context_t 2022-12-23 13:37:59 -07:00
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.

Behdad Esfahbod edf2738263 [colr] Try fixing bot build
I don't get the error. Let's see.

../../src/harfbuzz/src/hb-ot-color-colr-table.hh:574:66: error: incomplete definition of type 'OT::NoVariable<OT::ColorLine<OT::NoVariable>>'

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.

Matthias Clasen 0b33b35eb0 COLRv1: Return bool from paint_glyph
This will let hb_ot_font_paint_glyph() try
multiple tables in turn.

Matthias Clasen 0d890061d1 Rename 'solid' to 'color'
'solid' does not really describe well what
the function does, and there is no strong
reason to stick 1:1 to the terminology used
in the spec.
