Add "sendregion" command to GPU
This allows part of a buffer to be sent instead of the whole thing, meaning that driving digiscreen arrays can now be done with fewer commands and no temporary buffers.
This also greatly improves the speed of doing so, and I suppose also allows hardware-accelerated scrolling if your display is smaller than 64x64...
