To subscribers of the xforms list from spl@szechuan.ucsd.edu (Steve Lamont) :

It just occurred to me that another useful thing to look into is using
the shared memory extension to X. This will allow you to basically do
direct copies of image data to the X server rather than have to suffer
through the overhead of the client creating a whole flock of messages
to the server and the server processing them. Unfortunately not all X
servers support the XShm extension. You can determine if yours does
by using the xdpyinfo command. It should show something like

number of extensions: 5

If it shows MIT-SHM as above, then you win.

Of course, this only works if your client and your server are on the
same machine.
