* Creates a GeometryCollection geometry containing possible polygons formed from the constituent
* linework of a set of \a geometries. The input geometries must be fully noded (i.e. nodes exist
* at every common intersection of the geometries). The easiest way to ensure this is to first
* unary union these geometries by calling combine() on the set of input geometries and then
* pass the result to polygonize().
* An empty geometry will be returned in the case of errors.
* @note added in QGIS 3.0
