-<!--
-`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:
-
-    <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:
-
-    <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>
