As the resulting structure, represented by the Arrangement_2 class, stores pairwise interior-disjoint curves, the input curves are split at the intersection points before being inserted into the arrangement. A model of this refined concept therefore needs to compute the intersections (and possibly overlaps) between two x-monotone curves and to support curve splitting.
