Clutter should just require that the windowing system used by a backend adds a device to the stage when the device enters, and removes it from the stage when the device leaves; with this information, we can synthesize every crossing event and update the device state without other intervention from the backend-specific code. The generation of additional crossing events for actors that are covering the stage at the coordinates of the crossing event should be delegated to the event processing code. The x11 and win32 backends need to be modified to relay the enter and leave events from the windowing system.
