class TGLSceneInfo


 Base class for extended scene context.

 Scenes can be shared among several viewers and each scene needs to
 cache some viewer/camera/clipping specific state => this is a
 storage class for this data.

 Sub-classes of TGLSceneBase can override the virtual
 CreateSceneInfo() method and in it instantiate a sub-class of
 TGLSceneInfo containing the needed information. See TGLScene and
 inner class SceneInfo; note that some casting is needed in actual
 methods as TGLRnrCtx holds the base-class pointer.
