Thanks. It seems that the patch would not make things worse, at least.
I suspect get_glyph_face_and_encoding is not needed if `struct glyph'
contains `char2b' info and it is filled in append_glyph. That would
reduce the number of calls to rif->encode_char and enhance the
performance when CCL is thoroughly used as in Mac. But such a change
might be too drastic to do at this stage.
