   \brief Load raster map as integer map

   Calling function must have already allocated space in buff for
   wind->rows * wind->cols shorts.  

   This routine simply loads the map into a 2d array by repetitve calls
   to get_map_row.

   \param wind current window
   \param map_name raster map name
   \param[out] buff data buffer
   \param[out] nullmap null map buffer
   \param[out] has_null indicates if raster map contains null-data

   \return 1 on success
   \return -1 on failure,
   \return -2 if read ok, but 1 or more values were too large (small)
   to fit into a short (in which case the max (min) short is used)
