octave-nkf: src/DLD-FUNCTIONS/__voronoi_

annotate src/DLD-FUNCTIONS/voronoi.cc @ 13871:adf60d6dc1dd

more compatibility fixes for __voronoi__ * __voronoi__.cc (F__voronoi__): Use v option for qhull, not Fv. Improve argument handling. Call qh_findgood_all to obtain number of Voronoi vertices directly. Correctly size output values. Use qh_pointid to place cell indices in the same order as the given points.
