//       Class : DeferredNodeProperty
// Description : This class keeps track of all the state we must make
//               note of during the graph traversal, but cannot apply
//               immediately.  An instance of this class may be
//               assigned to nodes as they are created, and then later,
//               after the geometry has been created, the graph will
//               be traversed again and the state will be applied.
//
//               This class is only local to this package; it is not
//               exported.
