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 extent configured on the server, use the layer's
tileExtent property.
