Detailed Description

This is a base class for a generic data structure that can be attached per- instance to the camera, to store per-instance data that must be preserved over multiple frames.

In particular, this is used to implement the FadeLODNode, which must remember during traversal at what point it is in the fade, separately for each instance and for each camera.
