Implement partial support of Mac fonts on non-Mac platforms. * src/base/ftobjs.c (memory_stream_close, new_memory_stream, open_face_from_buffer, Mac_Read_POST_Resource, Mac_Read_sfnt_Resource, IsMacResource, IsMacBinary, load_mac_face) [!FT_MACINTOSH]: New functions. (FT_Open_Face) [!FT_MACINTOSH]: Use load_mac_face. * src/base/ftobjs.c (FT_Load_Glyph): Scale linear advance width only if FT_FACE_FLAG_SCALABLE is set (otherwise we have a division by zero since FNT and friends don't define `face->units_per_EM').
