From Emmanuel Roche, "I've also updated

the computeBound() method from the osg::Transform class : this
          method was using float based temporary variables and thus the
          double precision is lost here. I've changed that to use the
          generic types osg::BoundingSphere::vec_type and
          osg::BoundingSphere::value_type instead."
