void al_set_bitmap_blender(int op, int src, int dest)
Sets the function to use for blending when rendering to the target bitmap. If no blender is set for a given bitmap at draw time, the values set for al_set_blender(3alleg5)/al_set_separate_blender(3alleg5) are used instead.
To use separate functions for chroma (RGB) and alpha channels, use al_set_separate_bitmap_blender(3alleg5).
See al_set_blender(3alleg5) for more information about how blending works.
