Correct. As for adding another matrix slot into the gstate, we can
look into that again if there's ever a demonstrable reason to do this
for performance.

I don't think I've understood your comment here. Is it that you would
like an interface that would enumerate the acceptable family names
that could be passed to cairo_select_font? We could probably add that
