As an aside, its not obvious to me how to actually fix this bug.
Somehow the conversion from Box2D/Box3D to geometry needs to figure
out if the bbox has 0 width and/or 0 height and if so create a Point
instead of a Polygon.
The problem will live in the function that casts from Box* to GEOMETRY.
PostgreSQL does automatic casting, so
Extent(GEOMETRY) return BOX*
Centroid(GEOMETRY) returns GEOMETRY
PostgreSQL will rewrite Centroid(Extent()) to Centroid(Box2Geom(Extent())
