That part about adding bounding is no longer useful. It was useful to 
manually bound things back then, but, the automatic bounding have 
improved dramatically since 1993.
Now, not using those bounding often result in better performances.

Remember that adding bounded_by to an union suppress the normal bounding 
of it's components. That mean that any ray that enters that bounding box 
have to get tested against every individual primitives contained in that
