+ 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.
