Good heavens.  What figure is that?

I've been testing a case in which two geometries from an identical source are being compared, but some verts are missed in spite of the fact that they are indentical between meshes.  Looking at the code, it looks like identical meshes may represent an uncertain factor in the comparison process.  I found that by scaling either figure up or down slightly, the correlations turned out much better.  Apparently there can be problems with comparisons of verts which have identical coords.  Creating some slight difference in worldspace position, using scaling, seems to help that.

I'm trying to see if I can come up with a better handling, but this was Spanki's code area and I hesitate to muck it up.  Perhaps changing the scaling can help in your case, however.
