    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: fbit and NFNT bitmap resources are not supported yet.  In old
    sfnt fonts, bitmap glyph data for each size is stored in each `NFNT'
    resources instead of the `bdat' table in the sfnt resource.  Therefore,
    face->num_fixed_sizes is set to 0, because bitmap data in `NFNT'
    resource is unavailable at present.

    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().

    - Some suitcase fonts (notably Onyx) might point the `LWFN' file to
      itself, even though it doesn't contains `POST' resources.  To handle
      this special case without opening the file an extra time, we just
      ignore errors from the `LWFN' and fallback to the `sfnt' if both are
      available.
