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.

on color.

Matthias Clasen 56b02b6599 Update the docs
Mention that the color index will always be 0xFFFF
when using hb_paint API with fonts that don't have
color palettes.

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

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.
