 * The Damper class is a generic second-order critically damped system that does

 * DECAY_MILLISECONDS. This common parameter makes all states converge at the
 * same rate regardless of scale. xNormalization is a number to provide the
 * rough scale of x, such that NIL_SPEED clamping also happens at roughly the
 * same convergence for all states.
