  `paper-ripple` provides a visual effect that other paper elements can
  use to simulate a rippling effect emanating from the point of contact.  The
  effect can be visualized as a concentric circle with motion.
  
  Example:

25
26
27
      <div style="position:relative">
        <paper-ripple></paper-ripple>
      </div>
  
  Note, it's important that the parent container of the ripple be relative position, otherwise
  the ripple will emanate outside of the desired container.

  `paper-ripple` listens to "mousedown" and "mouseup" events so it would display ripple
  effect when touches on it.  You can also defeat the default behavior and
  manually route the down and up actions to the ripple element.  Note that it is

  important if you call `downAction()` you will have to make sure to call
  `upAction()` so that `paper-ripple` would end the animation loop.

  Example:
  
      <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
      ...
      downAction: function(e) {
        this.$.ripple.downAction({x: e.x, y: e.y});
      },
      upAction: function(e) {
        this.$.ripple.upAction();
      }
  
  Styling ripple effect:
  
    Use CSS color property to style the ripple:
  
      paper-ripple {
        color: #4285f4;
      }
  
    Note that CSS color property is inherited so it is not required to set it on
    the `paper-ripple` element directly.
  
  By default, the ripple is centered on the point of contact.  Apply the `recenters`
  attribute to have the ripple grow toward the center of its container.
  
      <paper-ripple recenters></paper-ripple>
  
  You can also  center the ripple inside its container from the start.
  
      <paper-ripple center></paper-ripple>
  
  Apply `circle` class to make the rippling effect within a circle.
  
      <paper-ripple class="circle"></paper-ripple>
