Soliciting for comments on smoothness of physics objects for this build. 

This introduces expected contact point hints to the ODE Collider to better determine when to throttle updates as excessive.   This /should/ smooth physics objects out again, however, I cannot know every configuration of OpenSimulator, so I'm requesting that testers please examine this change on their build.
Thanks!
