As we know, the bounds of this object are the points. No need to add the planes
as they introduce numerical imprecision.

[~ivera], unfortunately that is not true. This is a complex issue because
planes that are *almost* but *not quite* coplanar define shapes that actually
do have points on the opposite side of the world, within the precision limit of
geo3d. Random tests picked this up and I had to introduce addIntersection() to
deal with this situation, since I could not see a better way to handle very
thin rectangles using planes. Polygons also have this issue.

> Hi,
> It seems if I get the bounds of a BBox and I create a new bounding box,
> sometimes both bounding box are not equal. It is a problem with precision.
