         I'm removing this change until some issues can be addressed and I really
         think it needs to be implemented a better way anyway.
+
         First, it causes issues for anyone doing collideWith() with BoundingVolumes
         and expecting it to trickle down to the children.  For example, children
         with BoundingSphere bounding volumes and collideWith(BoundingSphere).  Doing
         a collision check at the parent level then has to do a BoundingSphere to BoundingBox
         collision which isn't resolved.  (Having to come up with a collision point in that
         case is tricky and the first sign that this is the wrong approach.)
+
         Second, the rippling changes this caused to 'optimize' collideWith() for this
         special use-case are another sign that this approach was a bit dodgy.  The whole
         idea of calculating a full collision just to see if the two shapes collide at all
         is very wasteful.
+
         A proper implementation should support a simpler boolean check that doesn't do
         all of that calculation.  For example, if 'other' is also a BoundingVolume (ie: 99.9%
         of all non-Ray cases) then a direct BV to BV intersects() test can be done.  So much
         faster.  And if 'other' _is_ a Ray then the BV.intersects(Ray) call can be done.
+
         I don't have time to do it right now but I'll at least un-break a bunch of peoples'
         code until it can be 'optimized' properly.  Hopefully it's not too late to back out
         the other dodgy ripples this caused.  -pspeed (hindsight-expert ;))
+
         Note: the code itself is relatively simple to implement but I don't have time to
         a) test it, and b) see if '> 4' is still a decent check for it.  Could be it's fast
         enough to do all the time for > 1.
