Adam Barth 06bfddff81 Drive overscroll animations with a physics simulation
This CL uses a simple physics simulation to drive overscroll animations.
We model settling the overscroll as a particle climbing a hill, which
gives us a pleasing parabolic trajectory.

This CL also includes machinery for spring-based simulations. We'll use
these to drive the drawer animation.
