--------------------------------------------------------------
This is the initial patch, without tests.
It's brute force when it comes to splitting up holes during breakup of
non-convex polygons into convex polygons; it just includes all of them with
each convex polygon created. That's not ideal because it misrepresents
intersections etc., but it should generally work.

> Real-world polygons (e.g. from ESRI) have holes in them. We need polygon
> support in geo3D that works in the same way.
> The proposal would be to change the GeoConvexPolygon constructor to include a
> number of GeoPolygon inputs, each of which would specify a hole. Then, the
> GeoPolygonFactory.makeGeoPolygon() method would also need to accept a similar
> list of GeoPolygon hole descriptions.
> This change is likely to be fairly complex because of the already tricky
> algorithm used to create convex polygons from non-convex ones, implemented in
> GeoPolygonFactory.
