surface_add_breakline
Surface breaklines — the TIN-forced edges (ridges / toes / pavement edges). add appends one polyline (>= 2 points, n_pts x/y/z triples) and re-enforces it on the triangulation; get copies up to max_pts (x,y,z) into out_xyz and returns the polyline's point count (call with out_xyz=null to size).
