Layer Min/Max Resolution

minResolution 1 maxResolution 1 resolution 1

Show/hide layers depending on current view resolution.

Zoom in twice: the MapBox layer should hide and the OSM layer should be shown.

If you continue to zoom in, you'll see the OSM layer also disappear.

The rendering of the layers are here controlled using minResolution and maxResolution options.
