<p>
The XYZ layer allows a zoomOffset to be set if you want to have
a maximum resolution for the map that differs from the maxiumum
resolution of the cached tiles. This example uses only 6 of the
levels in the cache, starting with the ninth level (index of 8)
in the cache. To do this, the layer is constructed with a
zoomOffset of 8. When the map zoom level is zero, the level
with index 8 will be requested from the cache.
</p>
<p>
See the <a href="xyz-offset.js" target="_blank">
xyz-offset.js source</a> to see how this is done.
