public class ScanexTileSource
extends TMSTileSource

This tilesource uses different to OsmMercator projection. Earth is assumed an ellipsoid in this projection, unlike sphere in OsmMercator, so latitude calculation differs a lot. The longitude calculation is the same as in OsmMercator, we inherit it from AbstractTMSTileSource. TODO: correct getDistance() method.
