   * marks the beginning of animation playback. After creating an
   * iterator, you should immediately display the pixbuf returned by
   * Gdk::PixbufAnimationIter::get_pixbuf(). Then, you should install a
   * timeout (with Glib::timeout_add()) or by some other mechanism ensure
   * that you'll update the image after
   * Gdk::PixbufAnimationIter::get_delay_time() milliseconds. Each time
   * the image is updated, you should reinstall the timeout with the new,
   * possibly-changed delay time.
   * 
   * As a shortcut, if @a start_time  is <tt>0</tt>, the result of
   * Glib::get_current_time() will be used automatically.
   * 
   * To update the image (i.e. possibly change the result of
   * Gdk::PixbufAnimationIter::get_pixbuf() to a new frame of the animation),
   * call Gdk::PixbufAnimationIter::advance().
   * 
   * 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."
   * @param start_time Time when the animation starts playing.
   * @return An iterator to move over the animation.
