  /**
   * This method tries to automatically determine SRS, bounding box and output size based on the
   * layers provided by the user and any other parameters.
   *
   * <p>If bounds are not specified by the user, they are automatically se to the union of the
   * bounds of all layers.
   *
   * <p>The size of the output image defaults to 512 pixels, the height is automatically determined
   * based on the width to height ratio of the requested layers. This is also true if either height
   * or width are specified by the user. If both height and width are specified by the user, the
   * automatically determined bounding box will be adjusted to fit inside these bounds.
   *
   * <p>General idea 1) Figure out whether SRS has been specified, fall back to EPSG:4326 2)
   * Determine whether all requested layers use the same SRS, - if so, try to do bounding box
   * calculations in native coordinates 3) Aggregate the bounding boxes (in EPSG:4326 or native) 4a)
   * If bounding box has been specified, adjust height of image to match 4b) If bounding box has not
   * been specified, but height has, adjust bounding box
