GtkSharp/gtk/Window.custom
Mike Kestner 9727ef31e2 2004-12-17 Mike Kestner <mkestner@novell.com>
* gtk/Gtk.metadata : hide Object and Widget.Destroy.
	* gtk/Object.custom : manual virtual Destroy impl.
	* gtk/Widget.custom : manual virtual Destroy impl.
	* gtk/Window.custom : hold a managed ref for all toplevels. Release
	it in a Destroy override.  Window is frequently subclassed and is
	never parented, so this keeps a managed ref around to avoid GC.
	[Fixes #70120]
