* A control displaying rough x-axis distances, calculated for the center of the

* A control displaying rough y-axis distances, calculated for the center of the
* viewport. For conformal projections (e.g. EPSG:3857, the default view
* projection in OpenLayers), the scale is valid for all directions.
* No scale line will be shown when the y-axis distance of a pixel at the
* viewport center cannot be calculated in the view projection.
* By default the scale line will show in the bottom left portion of the map,
* but this can be changed by using the css selector `.ol-scale-line`.
