The << operator for Coords has been slightly improved. The Gradient class now generated true-color output when indexed=false (and is used to generate true-color PNGs when PNG_INDEXED=false).

The GRIBIO plugin now reads a file name prefix from io.ini. It also properly convert the internal rotated lat/lon into geographic lat/lon and properly computes cell size. The georeferencing of grids is therefore now correct. The WMO standardized tables are now read first before trying alternate parameters. The documentation has been significantly improved.
