That fits in with my recent experience with sub-bitmaps being slow

Ok, discard that. I was calling al_set_display_icon() on each update
as well, which is apparently a bad idea (at least on OS X) if the
particular bitmap is a (sub bitmap of a) large bitmap.
Fixing that made subbitmaps run properly at normal speed for me...
