  * Converts the x and y indices of tiles to and from geo coordinates.

  *
  * Tiles do have the same width and the same height per zoomlevel.
  * The number of tiles per dimension is twice that of the previous lower zoomlevel.
  * The indexing is done in x dimension eastwards, with the first tiles beginning at -180 degree
  * and an x value of 0 and the last tiles ending at +180 degree,
  * in y dimension southwards with the first tiles beginning at +90 degree and a y value of 0
  * and the last tiles ending at -90 degree.
