[ODE] About angular damping

[Jon Watte (ODE)]

In the analytic case, yes; you get the angular velocity, multiply by the 
mass, and divide by the time step, negate it, and that's your necessary 
torque.

In the integrator case, there is always some behavior of the integrator 
that may get in the way, but I haven't analyzed the ODE integrator 
enough to correct for that -- I do what's outlined above, and it works 
pretty well as-is.

Cheers,
