+// 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.
