Two things I have thought about is refreshrate controll and off screen
memory management.

First refresh rate control is good for mpeg playing and 2d scroll games.
Its not fun to sync your 2d game to a 120HZ refresh that eats up all your
memory bandwitdth. I dont know if libggi can controll that now.

Second to make a square blitt of offscreen memory you have to use a
virtual screen and blit from that. This can be very bad as it is very
possible that every new src data line now happens to be in a different
dram page. This makes the blitt slow. Src data should be continous in
memory. That is a src block should not have any stride value on the data.
Can this be done now?
