Fix failure to load maps with arbitrary coordinate systems not based in meters. The cause was that the projection being set up didn't have a meter-per-unit value. For a meters-based coordinate system, OpenLayers provides one. For nearly everything else, OL won't provide one, so we need to provide one ourselves.
