The idea is to use all of the parameters to glBlendFunc that are shared 
between OpenGL and Direct3D. We just haven't got to that point yet.

There is already an al_draw_rotated_bitmap and al_draw_scaled_bitmap. 
Also, the current Allegro API (4.2) can draw rotated scaled bitmaps in 
software, so I don't see why they can't be done in software for 5.0.

As for having scaling and rotation as state in the bitmap, I personally 
think that may be a good idea, but it depends how statey we want to get.
