Know when a wobbling thing has stopped, and stop spending effort on it

Hundreds of springy objects on screen keep calculating forever for movements nobody can see anymore, and checking only whether it sits on its goal stops it too early, in the middle of a swing. Here is the right check and how to wake it again when something changes.

Why this works

A swinging thing is still when it is both close to its goal and slow, not just one of the two, because at the goal it is usually moving fastest. Putting it to sleep then costs nothing until something disturbs it.

When not to use it

Skip it when only a handful of things move, since the saving is then too small to be worth the extra rules. Also skip it for anything that must keep a tiny motion alive, like a floating item that always breathes.
