interface nsITaskbarPreview : nsISupports
   * The controller for this preview. A controller is required to provide
   * the behavior and appearance of the taskbar previews. It is responsible for
   * determining the size and contents of the preview, which buttons are
   * displayed and how the application responds to user actions on the preview.
   * Neither preview makes full use of the controller. See the documentation
   * for nsITaskbarWindowPreview and nsITaskbarTabPreview for details on which
   * controller methods are used.
   * The controller is not allowed to be null.
   * @see nsITaskbarPreviewController
  attribute nsITaskbarPreviewController controller;

   * The tooltip displayed above the preview when the user hovers over it
   * Default: an empty string
  attribute DOMString tooltip;

   * Whether or not the preview is visible.
   * Changing this option is expensive for tab previews since toggling this
   * option will destroy/create the proxy window and its registration with the
   * taskbar. If any step of that fails, an exception will be thrown.
   * For window previews, this operation is very cheap.
   * Default: false
  attribute boolean visible;

   * Gets/sets whether or not the preview is marked active (selected) in the
   * taskbar.
  attribute boolean active;

   * Invalidates the taskbar's cached image of this preview, forcing a redraw
   * if necessary
  void invalidate();
