2	Try doing bounds transformations with inverse transpose	byorgey	byorgey	The current scheme for applying transformations to bounding regions works, but is sort of complicated.  According to [http://www.unknownroad.com/rtfm/graphics/rt_normals.html this page], however, it seems like it may be possible to do the proper transformation more simply, in terms of inverse transpose transformations.  We could carry around the inverse transpose along with transformations (just as we currently carry around the inverse).  We ought to experiment at some point to see if this method will work, and whether it leads to less/simpler code and/or faster execution.	enhancement	closed	minor		core		fixed	bounds, transformations
