How do you do blending on locked bitmaps then? This must be possible for the primitive addon to work, otherwise it will need to implement al_draw_pixel that is allowed on locked bitmaps. Moreover, some people (Trent G. iirc) reported that locking the bitmap before calling a lot of al_draw_pixels was more efficient than not locking and using the hardware accelerated al_draw_pixel.
