- If there is a TrueType font (an 'sfnt' resource), read it into
memory, wrap it into a memory stream, load the TrueType driver
and delegate the rest of the work to it, by calling
tt_driver->interface.init_face( ... )
and delegate the rest of the work to it, by calling the init_face()
method if the TrueType driver.
- In both cases, the original stream gets closed and *reinitialized*
to become a memory stream. Additionally, the face->driver field --
which is set to the FOND driver upon entering our init_face() --
gets *reset* to either the TT or the T1 driver. I had to make a minor
change to ftobjs.c to make this work.
- We might consider creating an FT_New_Face_Mac() API call, as this
would avoid some of the mess described above.
