Detailed Description

Handles updating the scene graph when there is a new OpenGL context.

Through this class and its static members, all of the resources used in the scene graph are refreshed when the OpenGL context changes.

Each resource registers a refresh callback to the manager and then the viewer, when changin GL Contexts, calls newGLContext() to have the resources update.

If any new resources are added to the SceneGraph which have OpenGL-dependent memory (such as textures, display lists, arrays of data, etc.) that class must provide a static callback method and register it so its data can be restored in the new context (e.g. ImageData, Circle, Cylinder, etc.).
