Comment:

 With r9395 I added a different handing of 0-tolerance. That is, if you
 pass 0, which is the default, the code goes looking up
 topology.topology.precision (the tolerance you pass to CreateTopology) and
 if that's also zero ends up computing the minimum tolerance required to
 represent changes in the largest coordinate in input.

 There's no automated testing for the topology.precision use or lookup.
 Well, works fine with the cases we have so far. See #785 for more
 discussion about this.
