## Class Tooltip

      @IDProperty("id")
      public class Tooltip
      extends PopupControl

  Tooltips are common UI elements which are typically used for showing additional information about a Node in the scenegraph when the Node is hovered over by the mouse. Any Node can show a tooltip. In most cases a Tooltip is created and its `text` property is modified to show plain text to the user. However, a Tooltip is able to show within it an arbitrary scenegraph of nodes - this is done by creating the scenegraph and setting it inside the Tooltip `graphic` property.

  You use the following approach to set a Tooltip on any node:

       Rectangle rect = new Rectangle(0, 0, 100, 100);
       Tooltip t = new Tooltip("A Square");
       Tooltip.install(rect, t);

  This tooltip will then participate with the typical tooltip semantics (i.e. appearing on hover, etc). Note that the Tooltip does not have to be uninstalled: it will be garbage collected when it is not referenced by any Node. It is possible to manually uninstall the tooltip, however.

  A single tooltip can be installed on multiple target nodes or multiple controls.

  Because most Tooltips are shown on UI controls, there is special API for all controls to make installing a Tooltip less verbose. The example below shows how to create a tooltip for a Button control:

       Button button = new Button("Hover Over Me");
       button.setTooltip(new Tooltip("Tooltip for Button"));
