To step once, just pass your step size to dWorldStep() as the elapsed
time. While I generally don't like magic values, we could use a step
size of zero to indicate no iterations - just step the entire elapsed

If we made this change, how would collision testing be performed? If
testing is still done once per rendered frame, we would end up with a
variable number of steps between tests putting us right back where we
started. How do you folks run multiple physics steps between collision

An alternative to all of this would be to rewrite the tests to use
fixed steps, and also prominently display the information on the wiki,
maybe something like "My First ODE Application".
