My plan is to refactor OverlayNode so that the code for computing the
intersection code between the view frustum, the overlay geometry and
the scene would become part of CullVisitor, and osgUtil to also have
helper functions for setting up the various parameters required for
the shaders.  This would be to facilitate other techniques like shadow
mapping.

Alas if I only could clone myself then I'd have to time to do this...
