//       Class : PGCullTraverser
// Description : This is a specialization of CullTraverser for use
//               within the pgui system.  It is substituted in for the
//               normal CullTraverser by the PGTop node.  Its purpose
//               is to carry additional data through the traversal so
//               that PGItems can know how to register their regions
//               with the current MouseWatcherGroup.
