Path is the path through the graph to that node, it is usefull to
determine which copy of a single node you have reached if it exists
multiple times in the graph. It is not everything, just the immediate
ancestors of the specified node.

BUGS
     pfPrint is not yet implemented for pfGeoStates and other state
     structures, and is not implemented for pfPaths or pfLists.

These structures will not be found in a scene graph (except state).

Do you have a specific problem?
