Yes, copying from an RGB array into another RGB array on the client
side should be faster than sending the X request to copy the pixmaps.
However, the overall screen update time may or may not be better.

Copying between RGB buffers is going to be done with memcpy(), so no. 
You can use a mask when you render the final RGB buffer to the screen
though, or you could write your own copy routine that used a mask.
