mutter/clutter/win32/clutter-stage-win32.h
Neil Roberts 0b8a500fca Upgraded the Win32 backend to work with the multi-stage
subclassing code.

	* clutter/win32/clutter-stage-win32.h: 
	* clutter/win32/clutter-stage-win32.c: Now inherits from
	ClutterGroup and implements ClutterStageWindow instead of
	inheriting directly from ClutterStage.

	* clutter/win32/clutter-event-win32.c (message_translate): Now
	takes an extra parameter to return whether DefWindowProc should be
	called. This is needed to prevent the default WM_CLOSE handler
	from destroying the window.

	* clutter/win32/clutter-backend-win32.c
	(clutter_backend_win32_dispose): Destroy all of the stages using
	g_slist_foreach as per bug #871. Now also destroys the GL context.
	(clutter_backend_win32_get_features): Added assertions to ensure
	there is a valid GL context.
	(clutter_backend_win32_ensure_context): Accepts NULL stage. Gets
	implementation pointer from the stage.
