//jfcomment: This is never called, so pools are not maintained. I tried calling it before every use of new Voronoi, but it only slowed things down.
//Some of the _pools are used during voronoi computation, but the _sites._sites pool is only pushed into on _sites.Dispose.
//_pools are statics. Since I now maintain pointers to sites in Engine.nodes, there is no need to pool sites, and calling _sites.Dispose
//would fill up the _sites pool, and make a memory leak.
//I think the coder of Voronoi made a mistake to abuse iDispose and dispose to frustrate the gc (keep pools), it's the exact opposite of their normal usage.
//It would have been better to name them "recycle" or something.
