Unfortunately, it's more complicated. If the mod exists beyond a certain decimal
point, the parser must first clean up the vertex by the small part of float,
then check if a twin face exists.
I'll have to create a twin face search loop after writing the mesh with
formatting that trims small decimal points... that is, a loop nested within
another loop... a lot of runtime.
povray forgives a duplicate face, but the other formats I use do not (for an STL
this is a serious mistake)
