Thank you Paul. You've shown my point exactly. If you'd bother to
actually read the code you would see that this class does nothing. It
adds it to a list called VisibilitySensor and then forgets about it.
The old loaders need serious work to be a full VRML97 implementation,
and we are doing that work. Why not do some work yourself Paul?
