you're a little confused, i believe.

client-side software doesn't use the MIT-SHM unless its part of the Xlib
implementation that talks to the X server. its just way to (drastically)
reduce the amount of data passed over the serialized communication link
with the server. but its very very low level; even GDK (the drawing kit)
doesn't really mess with things at that level.

if you are writing stuff that renders images, you have no reason to
think about whether MIT-SHM exists or not - Xlib will take care of that
for you.
