Sure. but only it is. the important part of this specification IMHO
is, it provides a virtual font and has various parameters as a font,
which allows to override something in an real font. given that we do
support CFR in fontconfig, that would means we need to wrap up
FreeType APIs or reimplement similar thing to take effects them in the
worst case because we might not use FT_Face as is. this is why I think
that may be better getting involved with FreeType or needing some
hooks in FreeType to do what you said, which fontconfig is
responsible. I think we need to update both for CFR.

Yes, I think we have an RFE for that in bz. so that would be a good
opportunity to support it.
