Detailed 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.
