Mutter needs to fetch the X11 Window ID from the onscreen and did that by using an X11 specific API on the CoglOnscreen, where the X11 type was "expanded" (Window -> uint32_t). Change this by introducing an interface called CoglX11Onscreen, implemented by both the Xlib and GLX onscreen implementations, that keeps the right type (Window), while avoiding X11 specific API for CoglOnscreen.
