That's not exactly it: it means support for a different set of fonts, whose 
glyphs are multi-color pictures instead of monochrome shapes.

I asked about this feature two weeks ago, and got many replies (most of them 
lukewarm). I think Richard and you also replied:

Freetype has supported it since 2012. Emacs' has a direct interface to 
Freetype, but it seems to essentially be dead code. libXft doesn't expose 
Freetype's support for this feature, and I didn't get a reply from the devs on 
their mailing list about this. Cairo doesn't expose Freetype's support either, 
though Mozilla implemented support for it in their own branch. All in all it 
seems that it will be some time before GNU/Linux users get access to this
