Calculate a coordinate for a given point on the map in Mercator Projection.
Return
Returns a coordinate.
Parameters
coordinate
Point on the map in Mercator projection.
zoomScale
The current zoom factor applied on the map, is used to calculate the world size as tileSize * zoomScale (i.e., 512 * 2 ^ Zoom level) where tileSize is the width of a tile in pixels.
