Comment (by Lars Aksel Opsahl):

 Running with a tolerance off 1e-07 and do simplify input by find missing
 edge parts when topo error on second gives us a much better result as it
 seems. Number of topo errors are reduced from around 600 to less than 200.

 Related to gaps (missing areas) it's much better also. We had around 60
 areas that got lost, we are now down to one single polygon and that
 polygon is also a problem with zero tolerance. We may now have result that
 we actually can use.

 I will try create test case for that missing area later, but I have to
 work with other stuff now for days.
