    Notes

    Mac suitcase files can (and often do!) contain multiple fonts.  To
    support this I use the face_index argument of FT_(Open|New)_Face()
    functions, and pretend the suitcase file is a collection.

    Warning: Although the FOND driver sets face->num_faces field to the
    number of available fonts, but the Type 1 driver sets it to 1 anyway.
    So this field is currently not reliable, and I don't see a clean way
    to  resolve that.  The face_index argument translates to

      Get1IndResource( 'FOND', face_index + 1 );

    so clients should figure out the resource index of the FOND.
    (I'll try to provide some example code for this at some point.)

    The Mac FOND support works roughly like this:

    - Check whether the offered stream points to a Mac suitcase file.
      This is done by checking the file type: it has to be 'FFIL' or 'tfil'.
      The stream that gets passed to our init_face() routine is a stdio
      stream, which isn't usable for us, since the FOND resources live
      in the resource fork.  So we just grab the stream->pathname field.

    - Read the FOND resource into memory, then check whether there is
      a TrueType font and/or(!) a Type 1 font available.

    - If there is a Type 1 font available (as a separate 'LWFN' file),
      read its data into memory, massage it slightly so it becomes
      PFB data, wrap it into a memory stream, load the Type 1 driver
      and delegate the rest of the work to it by calling FT_Open_Face().
      (XXX TODO: after this has been done, the kerning data from the FOND
      resource should be appended to the face: On the Mac there are usually
      no AFM files available.  However, this is tricky since we need to map
      Mac char codes to ps glyph names to glyph ID's...)

    - 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 FT_Open_Face().
