The best way to create Inventor-like engines or to embed custom
behaviors in the scene graph is to have the loader define node
traversal callbacks that emulate them. In 1.2, these callbacks
would either have to be CULL callbacks or callbacks handled in
a user traversal (see libpfutil/trav.c). We expect that 2.0
will support an APP traversal to handle these things
automatically.

In the release after 2.0, Performer will support fields and
engines very much like Inventor's.
