Yes, and this will remain the way it is unless someone comes up with code to
determine the bounding box of a Catmull-Rom spline segment.  It turns out the
original sphere_sweep code simply adds a bit to the control point bounding
box.  The problem appears only for Catmull-Rom splines because they may exceed
their control points which the code uses to find the bounding...
