	* gdk/quartz/gdkwindow-quartz.c:
	(gdk_window_raise, gdk_window_lower, gdk_window_new,
	_gdk_windowing_window_destroy): Maintain a list for the stacking
	order of windows. Implement lower and raise for child windows. The
	list for toplevels is created on demand, and cleared when a window
	gets or resigns main status and when new windows are created.
	(find_child_window_helper): Use the sorted list to go through
	windows from top to bottom. Take any titlebar in consideration for
	toplevels, to stop events from sometimes punching through (bugs
	#473813 and #489370).
