[OSM-dev] WMS Overlay Disappears

[Thomas Wood]

This is more suited to the OpenLayers list, but at a guess it's
because of an incorrect maxResolution setting on the WMS layer, they
default to the Map, or if that's not set, auto-generated not always
successfully.

Setting up the Map object as shown here should be the first step to
getting the overlay to display.
