Robert does this require that we also need a seperate scenenode for each
scene view or can we use a single scenenode for all the sceneviews?
for example, is this safe to do?
///single root
osg::ref_ptr<osg::group> root = new osg::group;
...
for( i<n)
{
scenenview.push_back(new osgUtil::SceneView)
sceneview.back()->setScenesetSceneData(root.get());
}
...
Having a copy of the graph per sceneview seems inefficient but the question
arose so I thought I'd ask.

Ok. Since we are using a sceneview per context, sounds like we should be
okay making those calls into sceneview, right?
