All gluNurbs rendering examples (redbook and
Context-specific) are showing slow rendering rates,
particularly when a mouse-over occurs.

The was partially a problem with Context's mouse-event
queuing, at least under Context. It's still slow if you're
right up close to the object (it's rendering very high LOD
then), but is fine if you're some distance away.
Other part of the problem is that the geometry has no
optimised path for the selection rendering-pass, so it's
rendering the whole thing for each pass. Still, the samples
will render dozens of frames/second if there's no
mouse-over, so there's something fishy still going on.
Nurbs rendering is acceptably fast these days (though it may
simply be that the hardware has become much faster). Going
to mark this closed.
