../../src/harfbuzz/src/hb-ot-color-colr-table.hh:574:66: error: incomplete definition of type 'OT::NoVariable<OT::ColorLine<OT::NoVariable>>'
 2022-12-23 13:37:59 -07:00
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 37f3f0fcc2 [paint] Change the image callback 
Instead of passing the glyph ID, give

glyph extents (if available).

Update all callers.

on color.

Matthias Clasen 56b02b6599 Update the docs 
Mention that the color index will always be 0xFFFF

And add an outline about which kinds of glyphs
require which callbacks.

multiple tables in turn.
 2022-12-23 13:37:59 -07:00
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.
