I've now committed my algorithms in SDK/Extras/Utility Sources/ 
Mutating Algorithms.

I did some speed tests with a release build of Geom Test on my  
PowerBook.

* The original farmhouse ran at about 6 FPS.

* With extra references removed (the RemoveExtraReferences function),  
the speed was about 60 FPS.

* With some more algorithms, I got the speed up to about 370 FPS.   
The sequence of algorithms I used was:

RemoveExtraReferences
DecomposeGeometries
LowerAttributesToGeometries
FlattenHierarchy
OptimizeTriMeshes
MergeTriMeshes
