//       Class : CullBin
// Description : A collection of Geoms and their associated state, for
//               a particular scene.  The cull traversal (and the
//               BinCullHandler) assigns Geoms to bins as it comes
//               across them.
//
//               This is an abstract base class; derived classes like
//               CullBinStateSorted and CullBinBackToFront provide the
//               actual implementation.
