Hi!
Here's a patch that adds two new entries to GFX_VTABLE:
blit_between_formats(), for drivers that can do their own color conversion
(AllegroGL) and pivot_scaled_flip_sprite(), for drivers that can accelerate
these (and do the color conversion needed).
Hopefully, I didn't forget to change anything.
