This seems to be a misunderstanding.  Raph's speedy stuff is not about
parsing TrueType fonts but *rendering* outlines into bitmaps.  The
TrueType parser he has written in addition to the rasterizer was just
a proof of concept; it doesn't bring very much speed advantage.

As mentioned in another mail, Raph searches a volunteer for converting
it to C.  If you look at his code repository, the similarity to C is
quite high.
