        Demonstrates the use of transition effects in tiled and untiled layers.
    
    
    
        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.
    
        - The first layer is an untiled WMS layer with no transition effect.
- The second layer is an untiled WMS layer with a 'resize' effect. 
- The third layer is a tiled WMS layer with no transition effect. 
- The fourth layer is a tiled WMS layer with a 'resize' effect.
