Well, that conclusion appears to not be quite correct. I stuck a
XPending check at the end of X11DRV_EndGraphicsExposures to see whether
there were any pending events, and there were apparently none. So I am
not sure why the GraphicsExpose event is coming out before the regular
expose event, since in real time, they occurred in the opposite order.
