I just tested it out, and it didn't affect al_draw_bitmap(). (Not that
I expected it to, at least per the manual.) But it worked great when
using the primitive routines.
Is it feasible to add support to 4.9 that would allow transformations
to affect all drawing operations? I'm only interested in translations.
Allowing sub-bitmaps to have an origin that is negative would also
give me what I'm looking for. (Although I think moving the origin via
a translation would be nicer.)
