Returns 2D point list and facet list of a triangulated contour
Description
For ONE closed contour given by a (polybool) contour list, this function generates a tessellation by using the DelaunayTri functions. Without adding the desired points, the function return a tesselation with minimal points.
Use CPLmeltbool to avoid new crossing points in the triangulation
