Description

The attached postgresql dump contains 2 valid geometries, with a total of 201 points, that results in a TopologyException from GEOS when unioned togheter.

Postgis uses the CascadedUnion operation for this.

The same geometries have been tested against JTS with success [1]

Looks like having Geometry::Union use the BinaryOp heuristics fixes this case.

As of r3200 XMLTester supports unaryunion operation. I've pushed an XML test for this item in r3204.

r3206 fixes this by swithing to the use of BinaryOp from Geometry::Union
