[ODE] why setTransform() ?

Excellent fpoint discussion snipped.

Right.  Of course, ODE needs to stay general, so I think both need to be
in there.

RenderWare used to have a nice library and Macro's for doing fixed point
or floating point.  

I do think we should benchmark float vs double; I'm not as close to the
hardware anymore, but I could take a shot on the PC side.  I'm running
some large tests that did hammer the stack, so I could put in some
QueryPerformanceCounter's here and there.  I'm doing some work that'll
export to POVRay (ray tracing) in which the rendering times will be
minutes to hours per frame, so performance is an issue but not as much -
however, my scene complexity will be higher than a game as a result.
