[ENH] Support for multicolour fonts #31206
Description
As with regular fonts, there exist several different formats encoding a colour glyph in a font. Some of these are directly supported by FreeType, but for some it only exposes the underlying data and cannot render them.
This is a meta issue for the purposes of documenting the lack of support of each individual type and a tracking issue for implementations.

Maybe you could provide (here or in each child issue) links to example font files for each format.

The recently released harfbuzz 13 appears to have implemented (experimental) support for (colorful) svg glyph rasterization (I only noticed it in the changelog, haven't actually tried it); maybe that'll fix all the problems for us at once? :)
