Applied patch from bug #810.

	* clutter/x11/clutter-event-x11.c (event_translate): Set a flag
	when resizing the stage from a ConfigureNotify event.

	* clutter/x11/clutter-stage-x11.c
	(clutter_stage_x11_request_coords): Don't try to resize the window
	again if the flag is set.
	(clutter_stage_x11_init): Added initialiser for the flag.

	* clutter/x11/clutter-stage-x11.h (struct _ClutterStageX11): Added
	the flag.

the window a second time. However if the stage is resized
multiple times without the events being processed in between
(eg, when calling g_object_set to set both width and height)
then there will be multiple ConfigureNotify events in the

the second property which will cause it to keep generating
