Increases the size of the "frame" used to initialize the Incremental Delaunay Triangulation subdivision. This improves the robustness of constructing triangulations which contain very narrow triangles along the edge of the subdivision.
Originally reported as a failure in the Concave Hull algorithm in libgeos/geos#719. The failure was caused by the constructed triangulation failing to contain triangles which covered the convex hull of the input.
Issue #477 has more failure cases that this solves.
