+    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.
