What about fonts which don't use FONT_GLYPHs or BITMAPs? Perhaps it uses
an RLE sprite or something. Then what? You could get a pointer to the
glyph, but you wouldn't know anything about it.

What is wrong with text_length()? It is more general (ie. because we
don't have to access individual glyphs and add up their lengths, we can
just ask the library to do it for us).

Bye for now,
