+`paper-dialog-scrollable` implements a scrolling area used in a Material Design dialog. It shows
+a divider at the top and/or bottom indicating more content, depending on scroll position. Use this
+together with elements implementing `Polymer.PaperDialogBehavior`.

+    <paper-dialog-impl>
+      <h2>Header</h2>
+      <paper-dialog-scrollable>
+        Lorem ipsum...
+      </paper-dialog-scrollable>
+      <div class="buttons">
+        <paper-button>OK</paper-button>
+      </div>
+    </paper-dialog-impl>
+
+It shows a top divider after scrolling if it is not the first child in its parent container,
+indicating there is more content above. It shows a bottom divider if it is scrollable and it is not
+the last child in its parent container, indicating there is more content below. The bottom divider
+is hidden if it is scrolled to the bottom.
