Demonstrates the use of the tileExtent property to differentiate between the maximum extent and the tile extent for a layer.
                This example uses a layer that requests map tiles from a WMS
                that only generates image responses for requests that align with
                a particular tile lattice.  In this case, the layer's 
                maxExtent does not align with that tile lattice.  
                To configure the layer with a tile extent that conforms to the 
                tile origin configured on the server, use the layer's 
                tileOrigin property.
