I think you are jumping to conclusions here. The only glyphs for which this
is a problem
with the current code are color glyphs. Most glyphs are still fine with
other operators. One
answer I gave on irc is: if you want to do fancy stuff with text, you
better control which
fonts are involved, so use a custom context (which can avoid loading color
glyphs for the
emoji family). But that is not a great answer. Some ideas for a better one:
- Add an api to find out if a fond has color glpyhs
- Add an api to control loading of color glyphs
- Clip when painting color glyphs to not affect the target outside the
extent of the glyph

I can take a look at docs. No idea about the web page.
