That does seem like a useful function to have. It's sort of a 
generalization of `al_draw_glyph`.

Also, we could add a callback to the font itself to cache glyphs on a 
bitmap of your choosing, so you could e.g. stick it onto an atlas with 
the rest of your sprites. Then you could really draw everything in a 
single draw call.
