The natural way to manage a application that was two views on to two
different scenes is to use a osgViewer::View for each separate scene, and
then a osgViewer::CompositeViewer to manage these two scenes.  These two
views can share the same GraphicsWindow, or have their own.  They may even
be added/removed from the CompositeViewer, or have their rendering toggled
on/off via NodeMask's on the master Camera for each View.
