[winswitch] testing required: OpenGL client rendering

[Nick Burrett]

I'm trying this out with the xfce4 terminal - /usr/bin/Terminal on Ubuntu
quantal (12.10)

Rendering is certainly faster, however just moving the mouse across the
various menu items at the top of the window will flick between the current
image and a previous window image and will regularly produce this:
