      * 
      * Parameter:
      * resolution - {Float}
+     * closest - {Boolean} Find the zoom level that corresponds to the absolute 
+     *     closest resolution, which may result in a zoom whose corresponding
+     *     resolution is actually smaller than we would have desired (if this
+     *     is being called from a getZoomForExtent() call, then this means that
+     *     the returned zoom index might not actually contain the entire 
+     *     extent specified... but it'll be close).
+     *     Default is false.
      * 
      * Returns:
      * {Integer} A suitable zoom level for the specified resolution.
      *           If no baselayer is set, returns null.
