Rework how we get the event window: don't get the window from the NSEvent,

	* gdk/quartz/gdkevents-quartz.c (find_mouse_window_for_ns_event)
	(find_window_for_ns_event): Rework how we get the event window:
	don't get the window from the NSEvent, always use the mouse window
	instead. Fix mouse window tracking by only using MouseExited for
	non-gdk windows, and to always use the NSEvent window to get the
	right gdk window in MouseEntered. Add comments to the code. Fixes bug
	#350460.
