I had a look at the cirrus rop code, it's not optimized yet, even in CVS.
I think that's the problem.
I don't know the hardware specs of the cirrus, but where's the limit of its
hardware support?
Is it really necessary to implement a new graphics card?
Area copying and area filling is already possible, although not optimized.
This question might be stupid but why not using
SDL_FillRect(...) and
SDL_BlitSurface(....).
?
I think SDL accelerates these operations if supported by your driver.
