CameraGroup supports cameras opened in different windows or in the same window, with flexible view and perspective specification. Clean up mouse click handling via osgViewer. Don't let any camera "have focus;" this forces events to be reported in window coordinates and simplifies life. Don't use the osgViewer::View::requestWarpPointer method; instead use our own code which only deals with window coordinates. Make glut and sdl versions work with CameraGroup too.
