 Since fixes in the GEOS snap algorithm some tests for topology (tolerance-
 based) are failing due to different result (better results, IMHO).

 The test needs to be tweaked to either work in both cases or only with the
 latest release.

 .. to be honest the tolerance support in topology should really be
 refactored to use SnapToGrid...
