Subject: [PATCH] Move the checks for no window or a non-GDK window from
 here...

2007-06-16  Richard Hult  <richard@imendio.com>

	* gdk/quartz/gdkevents-quartz.c (find_mouse_window_for_ns_event):
	Move the checks for no window or a non-GDK window from here...
	(gdk_event_translate): ...to here. Reorder the code so that we
	detect the cases where we need to break grabs before bailing
	out.
