Why can't we just use AL_BITMAPs everywhere? AL_DISPLAY introduces
uneeded complexity in those nasty corner cases (which basically makes
the hard part even harder). Using AL_BITMAPs everywhere gives us bounded
complexity: We already know how to handle it because that's what Allegro
is currently doing!
