 * for example, it may be stored as a sprite and instructions for moving the sprite around a background.
 * To display an animation you don't need to understand its representation, however; you just ask

   * If you're using Gdk::PixbufLoader, in addition to updating the image
   * after the delay time, you should also update it whenever you
   * receive the area_updated signal and
   * Gdk::PixbufAnimationIter::on_currently_loading_frame() returns
   * <tt>true</tt>. In this case, the frame currently being fed into the loader
   * has received new data, so needs to be refreshed. The delay time for
   * a frame may also be modified after an area_updated signal, for
   * example if the delay time for a frame is encoded in the data after
   * the frame itself. So your timeout should be reinstalled after any
   * area_updated signal.
   * 
   * A delay time of -1 is possible, indicating "infinite."
