That's excellent news -- especially the speed up on the trigonometric  
functions. What sort of PowerPC were you benchmarking against?

I may not have received all my emails the last few days since I'm  
away on the Apple WWDC Roadshow "down under", is this a compile on  
gcc 3.4 with the proper use of __bool and __pixel?

When you are ready, a diff would be good, or you can send me  
everything and I can do a branch in the Subversioned code to get it  
reintegrated back.

Cheers,
