	* gdk/quartz/gdkwindow-quartz.c:
	(gdk_window_impl_quartz_invalidate_maybe_recurse):
	(gdk_window_quartz_update_idle): Use gdk_threads_add_idle instead
	of g_idle_add. Add a temporary check if the window is already in
	the updates list, since update_area currently doesn't always match
	the backend's state, see bug #530801.
