Hmm, that's an optimization, right? A simplification? (To assume that
sin(theta)=theta, works for small angles) Is that perhaps where the
"bendy wheels" bug is coming from? Would it be possible to choose
whether or not to use this simplification? Or would it be so slow to use
a real sin() that it won't be usable at all?
