	Make gtk_widget_set_extension_events() work on already realized
	widgets (bug #379550, Tommi Komulainen)

	* gdk/x11/gdkinput.c (gdk_input_set_extension_events): allow to be
	called multiple times without leaking and work correctly when
	already realized (don't rely on a configure event following).

	* gtk/gtkwidget.c (gtk_widget_set_extension_events_internal): new
	internal function which walks the GdkWindow tree and sets the
	extension events on all windows that belong to the widget.

	(gtk_widget_realize)
	(gtk_widget_set_extension_events): use the new function.
