	    <see cref="M:Gdk.PixbufAnimation.GetIter" />, and must increase or remain
	    unchanged each time this method is
	    called. That is, you can't go backward in time; animations only
	    play forward.
	  </p><p>
	    As a shortcut, pass <see langword="null" /> for the current time and g_get_current_time()
	    will be invoked on your behalf. So you only need to explicitly pass
	    <paramref name="current_time" /> if you're doing something odd like playing the animation
	    at double speed.
	  </p><p>
	    If this method returns false, there's no need to update the animation
	    display, assuming the display had been rendered prior to advancing;
	    if true, you need to call 
	    <see cref="P:Gdk.PixbufAnimationIter.Pixbuf" /> and update the
	    display with the new pixbuf.

	  Gets the current pixbuf which should be displayed; the pixbuf will
	  be the same size as the animation itself
	  (<see cref="M:Gdk.PixbufAnimation.GetWidth" />, <see cref="M:Gdk.PixbufAnimation.GetHeight" />). This pixbuf should be displayed
	  for <see cref="P:Gdk.PixbufAnimation.DelayTime" /> milliseconds. The caller
	  of this function does not own a reference to the returned pixbuf;
	  the returned pixbuf will become invalid when the iterator advances
	  to the next frame, which may happen anytime you call
	  <see cref="M:Gdk.PixbufAnimationIter.Advance" />. Copy the pixbuf to keep it
	  (don't just add a reference), as it may get recycled as you advance
	  the iterator.
