Support setting threshold for custom properties
This CL removes the (unreleased) APIs set/getVelocityThreshold,
as the velocity threshold is not a straight forward idea, and
it requires develoeprs to convert a per frame threshold to
per second.
Instead, set/getMinimumVisibleChange(float) is added. This expects
a minimum value change that is visible to end users. This value
is then used to calculate a reasonable velocity and value threshold
for animations.

Physics-based animation - SpringAnimation
This CL introduced physics-based animation. Specifically,
SpringAnimation and its base class DynamicAnimation.
This new set of Animation APIs track velocity of the
animation, and they no longer assume a fixed duration.
As a result, interruptions to animations are now handled
much more smoothly, as the velocity change is always
continuous.
SpringAnimation is driven by a SpringForce that calculates
the update of the animation's value and velocity on each
animation pulse until the spring reaches equilibrium.
Test: 100% public API coverage in this CL
