So about a 6X improvement with this round. Well my cup is half full :-)
We'll see how it looks with the next round of performance improvements. In
the long run I am probably going to add an ActorIsStatic type of ivar that
user's can set in this situation what will yield huge performance
improvements. This was something people wanted even in VTK 4.4 because if
the actors truly are static the top render rate has always been pipeline
limited for large numbers of actors with low poly count. Having said that, I
still want to tune the pipeline first to see where we stand.

Thanks
