OpenSceneGraph/include/osgViewer/StatsHandler
Robert Osfield abd0c7fe67 Added support for sorting the graphics contexts so that the first context/window
returned from Viewer::getContexts/getWindows will be the left most window on the lowest screen number.

Added ability for StatsHandler and HelpHandler to support end users setting their
Camera's graphics context.
