PeasyCam change/disable DampedAction

I have an urgent question about PeasyCam's damping property.. When I use PeasyCam to rotate a 3D object, after the mouse stops the object still moves with a decreasing velocity (damping). PeasyCam has a class called DampedAction for this movement. My question is: How can I change the damping value (original 0.16) or disable the damping property. For example in the PeasyCam sample bellow I would like to change (extend) this class in peasy library or Override it.. How is it possible to do it in this code:

import peasy.*;

PeasyCam cam;

void setup() {
  size(800,600,P3D);
  cam = new PeasyCam(this, 100);
  cam.setMinimumDistance(50);
  cam.setMaximumDistance(500);
}

void draw() {
  rotateX(-.5);
  rotateY(-.5);
  background(0);
  fill(255,0,0);
  box(50);
  pushMatrix();
  translate(0,0,30);
  fill(0,0,255);
  box(5);
  popMatrix();
}

Thanks for any help!..
