I'm looking for any tips or code examples of fast memory moves
from some location in memory directly to video memory.  I realize 
that this isn't good X practice but I need very fast (30 frames/sec)
animations.  My window is 256x256x8.  The data is actually
coming from a board on the bus.

Please respond if you have any fast animation experience with X.
I don't think XPutImage is going to cut it.  Especially since I'll
have to form an XImage from the raw x,y,color data coming in from
the board.

Thanks in advance,
george
