I've wondered about this myself - why does /everything/ have to be in
double precision? Do I really need that extra precision in the lengths
of my box sides? Does it really help in the quaternions? It seems like
we could save a lot of memory by only using doubles where they
actually bought us something. It would be a straightforward -- if
labor intensive -- modification.
