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 2333a566ed Drop the deprecation
No need to drop hb_font_get_glyph_shape, just
because hb_font_draw_glyph does the same.

Its fine to keep both around.
2022-12-23 13:37:59 -07:00
Matthias Clasen 14b026ff86 [draw] Add hb_font_draw_glyph
hb_font_draw_glyph(), hb_font_draw_glyph_func_t and
hb_font_funcs_set_draw_glyph_func() are just alternative
names for hb_font_get_glyph_shape and friends, to better
align with hb_font_paint_glyph.
