"tile2path($tilex, $tiley, $zoom)" Composes the path to the tile at
$tilex, $tiley, and $zoom at the OSM server. $tilex and $tiley
must be integers in the range "0..2**$zoom-1". The supported
range of zoom levels depends on the tile server. The maximum zoom
for the Osmarender layer is 17, it is 18 for the Mapnik layer.
I believe 18 has changed. Perhaps don't mention actual numbers.
