I guess this not necessarily a public API, right?

OK, thanks. I'll start moving the current code to such a new
function. Let's first set up everything so that I can finally see
colored glyph layers in `ftview' :-) We can then improve the code,
also adjusting the API if necessary.

Why? I don't see a necessity for this restriction. As mentioned in
my last e-mail, BGRA bitmaps should be handled the same, so I think we
should allow bitmap objects also.

OK.
