	* gdk/quartz/gdkprivate-quartz.h:
	* gdk/quartz/gdkwindow-quartz.c (find_child_window_helper)
	(_gdk_quartz_window_find_child): Refactored version of
	_gdk_quartz_window_find_child_by_point, that doesn't return any
	coordinates as the users of this function already have the
	coordinates and need to translate them differently.
	(_gdk_windowing_window_get_pointer): Fixup coordinate translation.
	(_gdk_windowing_window_at_pointer): Likewise.
