BoundingSphere is similar to a bounding box, but more spherical. SOverlaySphere is useful for visualising BoundingSphere (it's quite inefficient and should only be used for debug functionality). Normalise the camera frustum clipping planes, so that IsSphereVisible gives the correct result. This was SVN commit r15261.
