[postgis-devel] ST_VoronoiDiagram first cut

[Komяpa]

Hi!

That's cool!

We needed Voronoi Polygons half a year ago in our analytics, so I searched
for solution and wrapped it into a function:

https://github.com/wgnet/globalmap/blob/master/code/postgis_wrappers/ST_VoronoiPolygons.sql

You can probably find it useful when preparing testcases or experimenting
with signature.

>   If the function is added to PostGIS 2.2, I can commit to writing the

> (I have not added the new internals yet, nor the test contents -- this is
