Make WidgetSprite can be the whole scene background

[steve3d]

I've alreay posted a thread about this. seems only ulf saw the thread, and no one except me need this.

 

Use ObjectGUI can do this of course, but it need more work, for example, I have to place ObjectGUI exactly covered all camera viewport to be used as background.

 

and it should be easy to do in engine.
