It seems my eyes were not to be trusted, I use the hierarchy for Level
Of Detail visualization. When computing the bounding sphere of each
node from scratch, it works really fine. But when reusing some
Min_sphere_of_sphere_d's... the display of LOD is somewhat erratic, so
there might be more to do than a simple l.clear(), but I will also
investigate if the problem does come from my non-CGAL code or not.
