That's been FreeType workhorse since 2.0. You gotta draw those glyphs
on a bitmap. It is funny you should mention how expensive divisions
there, because I've just committed a faster alternative with reduces
the number of divisions to a bare minimum. I bet all gray_functions
will remain on top with perhaps 50% combined. Please let me know how
much exactly. Anyhow, there is not much left to do or fuzz after
rendering, so do not render or short-cut it in the fuzzer.
