You can configure an OpenStreetMap tile server, e.g.:
Name=Smoothness,
URL=https://tile.bbbike.org/osm/bbbike-smoothness/${z}/${x}/${y}.png
or cut & paste image
URL=https://tile.bbbike.org/osm/bbbike-smoothness/15/17602/10746.png
If isBaseLayer is set to "no", the map will be used as on overlay map.
