Yep, doing it the mozilla way throws away the hinting information, but
the link was useful though. What I wanted to do was to embed the entire
font in the output, and Owen pointed me to
as an example of code that accesses the face->stream field of an
FT_Face. That field is marked as private but seems to have become part
of the public API.
What I ended up doing though, was writing subsetting code after all. I
have patch that I just need to clean up a bit, then I'll send it to the
