Example reproducing the bug

When resizing an X window, the GLX context isn't resized. This bug appears when
using XSetEventQueueOwner(dpy, XCBOwnsEventQueue) and using xcb to read events
(xcb_poll_for_event or xcb_wait_for_event), but not when using XNextEvent to
read events.

Comment out #define USE_XCB in the supplied example and the GLX context is
resized as expected.

System information:
2.6.38-3-generic
Ubuntu 10.10
Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
OpenGL version string: 2.1 Mesa 7.11-devel
