-paper-ripple
-============
-
-`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:
-
-```html
-<paper-ripple></paper-ripple>
-```
-
-`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:
-
-```html
-<paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
-...
-<script>
-  downAction: function(e) {
-    this.$.ripple.downAction({x: e.x, y: e.y});
-  },
-  upAction: function(e) {
-    this.$.ripple.upAction();
-  }
-</script>
-```
-
-Styling ripple effect:
-
-Use CSS color property to style the ripple:
-
-```css
-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.
-
-```html
-<paper-ripple recenters></paper-ripple>
-```
-
-Apply `center` to center the ripple inside its container from the start.
-
-```html
-<paper-ripple center></paper-ripple>
-```
-
-Apply `circle` class to make the rippling effect within a circle.
-
-```html
-<paper-ripple class="circle"></paper-ripple>
-```
