* Emoji: colour glyphs, and emoji take the colour emoji font
Emoji were drawn as black outlines from a symbol font, with ZWJ sequences
(families, flags) falling apart into their parts. Now:
- an emoji cluster (emoji presentation, U+FE0F, ZWJ between pictographs,
skin tones, regional indicators, keycaps) takes an installed colour font
(COLR, CBDT, sbix or SVG tables) before the document's fonts, so its
sequences ligate as in PowerPoint; U+FE0E keeps a plain face;
- COLR v0 and v1 glyphs are painted in their CPAL colours (solid fills,
linear, radial and sweep gradients, transforms, composite modes), with
palette index 0xFFFF in the text colour.
A tiny COLRv0 test font (two squares, CC0, regenerated by
make_colr_font.py) backs the render test.
