fastjet/internal/delaunay: border points in voronoi diagram

Created by: Bastiantheone

How should I go about points on the outside in the vornoi diagram? I could either return the voronoi diagram where the voronoi points on the outside connect to a user defined border, or I could return it where voronoi point on the outside connect to their neighbor. The second option would be easier and probably be more useful, but the first version will definitively look better when plotted. I have planned to return the area, so the area for points on the outside would be infinity and therefore users can identify those easily. Is there a way to make a line go towards a direction with the gonum plotter? In that case I would like to create a polygon that doesn't connect on all sides. If that's possible it would be a way to use the second option and make it plot nicely.
