[Papervision3D] Performance check and optimsation tips please

Hi Peter

It's for a desktop app that will be left to run on the BBC's big screen

but cheers for the advice, sometimes I think we start coding with all the
best intentions in the world, then we inevitably end up with a hack or
fourteen.

Cheers
Gareth
