Could we use the existing caching code but extend it a bit to create a 
cleaned up version of any TriMesh which we find is dodgy,  and use that 
instead?


We could also provide a routine to clean up a TriMesh.

We could also have two extra flags in a TriMesh to say if it has been 
tested and if so whether it was clean or not.
