Currently doesn't work though, we detect font fallback. Apparently

should know how to return the full font blob.
Based on patch from Konstantin Ritt.

[coretext] Avoid font fallback with CoreText shaper
CoreText does automatic font fallback (AKA "cascading") for characters
not supported by the requested font, and provides no way to turn it off,
so detect if the returned run uses a font other than the requested one
and fill in the buffer with .notdef glyphs instead of random indices
glyph from a different font.

[coretext] Fully support user features
Based on patch from Jonathan Kew and data from Apple.
It's not working correctly though, and I suspect I'm hitting a bug in
CoreText. When I do this:
hb-shape /Library/Fonts/Zapfino.ttf ZapfinoZapfino --shaper coretext \
--features=-liga
I expect both ligatures to turn off, but only the second one does:
[Z_a_p_f_i_n_o=0+2333|Z=7+395|a=8+285|p_f=9+433|i=11+181|n=12+261|o=13+250]
whereas if I disable 'dlig' instead of 'liga', both are turned off.
Smells...
Doesn't resolve conflicting feature settings.
