Fix a run time warning.
…window Make sure the destroy handler does not attempt to remove the window from the application after it has already been removed.
ClutterTexture has been deprecated, so this patch removes API that exposes ClutterTexture and replaces the use of ClutterTexture internally. In most cases, ClutterTexture can be replaced by CoglTexture, which should also improve performance. This patch also removes the MxTextureFrame actor (which depended on ClutterTexture) since it was not useful on its own and can be implemented in other actors by using the mx_texture_frame_paint_texture utility function.
Avoid using MxBin to allow the ClutterActor child management functions (such as clutter_actor_add_child) to work correctly.
