        There are two transitions that are currently implemented: null (the
        default) and 'resize'.  The default transition effect is used when no
        transition is specified and is implemented as no transition effect except
        for panning singleTile layers.  The 'resize' effect resamples the current
        tile and displays it stretched or compressed until the new tile is available.
