I think that might have been my idea; regardless I remember the
discussion. I guess I don't see why you would /ever/ need doubles for
object-relative coordinates like box side lengths or a cylinder
radius. How much does double-precision really buy you in the
quaternions and  rotation matrices? It seems like there might be a
possibility to reduce the memory bandwidth of the double-precision
build by identifying the places where the extra precision is actually

If there are no significant drawbacks, I'll drop it on the feature
request list and look at it...eventually.
