Detailed Description

Based on osgUtil::SceneView, but stripped done to only render and not interfere with stereo setup.

SceneView is deprecated, and is now just kept for backwards compatibility. It is recommend that you use osgViewer::Viewer/Composite in combination with osgViewer::GraphicsWindowEmbedded for embedded rendering support as this provides a greater range of functionality and consistency of API.
