    surface-actor: Unref shaped texture on dispose
    
    The MetaShapedTexture created by MetaSurfaceActor used to
    be a ClutterActor, which means destruction was taken care
    by Clutter.
    
    Now that it's a plain GObject, we need to manually clean it
    up.
    
    Cleanup the shaped texture on disposal.
