[Papervision3D] PreciseBitmapMaterial crashing browser

[John Grden]

sweeet thanks Rob!

Hey Rob, I had also seen, when appying the Precise materials to an object,
that when I rotated it, I saw cracks or what seemed to be faces not drawn -
not totally sure.  Would changing the ration like Andy talked about help
that out?  or do you know of other issue?

Thanks man, appreciate your help very much,

John
