Is there some chance to have it faster for 180 degree rotation (i.e. for 
left handed people using N770) preferably without shadow buffer?

For 180 degree rotation writing to place framebufferstart+x means in 
fact writing to place framebufferend-x, correct? Can this be done 
transparently without additional copy of framebuffer on some abstraction 
level?
