Thanks Eli. I'm rather familiar with these documents. But my question was not
about this; it was about fonts that embed truly multicolor images for specific
codepoints (support for variation selectors is another question entirely, I
believe). There are various implementations of multicolor fonts, as pointed out
by the document that I originally linked to. For example, Apple does it by
packaging a collection of PNGs and calling that a font. Microsoft does it with
multiple layers of single-color SVGs. I was curious to know whether Emacs
supports any this, and on which platforms.
From some web searches, it seems that Emacs definitely does support the "PNG
packages as a font" technology developed Apple, in the native port of Emacs to
MacOS. I'm not sure who implemented this support, and who maintains it. Perhaps
the insight of that person would be useful in generalizing this feature to
other platforms that Emacs runs on.
