Well its all about reducing guest CPU usage to increase density, and I
haven't done a massive test yet, other than glxgears -fullscreen
inside a VM went from 90FPS to 135FPS, so I expect a CPU usage drop
for texture from pixmap will be quite decent as well though I don't
have a good benchmark for it.
