For a long time now I've liked to have a fullscreen RViz camera display. I took a look at the calls that the Oculus plugin makes to make its window fullscreen, but the same doesn't seem to work with ImageDisplay or CameraDisplay.

I feel like this shouldn't be hard, but I'm not too familiar with the RViz, Qt, and Ogre APIs, so I don't know what the best approach is. If it's something simple, and someone could give me some guidance, I could do it and post a PR.
