Karl Wright updated LUCENE-7154:
--------------------------------
    Attachment: LUCENE-7154.diff

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 idea 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.
