/* When running as an X11 compositor, we install our own event filter and

* handling our events.
*
* However, when running as a Wayland compostior under X11 nested, Clutter
* Clutter needs to see events related to its own window. We need to
* eventually replace this with a proper frontend / backend split: Clutter
* under nested is connecting to the "host X server" to get its events it
* needs to put up a window, and GTK+ is connecting to the "inner X server".
* The two would the same in the X11 compositor case, but not when running
* XWayland as a Wayland compositor.
