	Continue the event handling cleanup:

	* gdk/quartz/gdkevents-quartz.c: (synthesize_crossing_events):
	Don't do anything if the old and new windows are the same,
	simplifies the callers.
	(find_mouse_window_for_ns_event): Always return a window (root
	instead of NULL). Remove unneccessary check for the current mouse
	window being NULL, that was a workaround for a now fixed
	bug. Convert to root coordinates if we don't find a window.
	(synthesize_crossing_events_for_ns_event): Simplify and add
	comment.
