The CNRM plugin can now be enabled and properly works. Its documentation has been updated and improved. The NetCDF plugin can now read DEMs using various schema/conventions and its documentation now matches the code. A few more MeteoGrids have been defined that are required for meteorological model outputs and for some future spatial interpolations (ISW_DIR, ISW_DIFF for example). The PNG plugin creates a few more EXIF fields in order to make it very easy to integrate in google earth (but it seems that google earth does not like indexed pngs). A bug computing the geolocalization of grids coming from NetCDF has been fixed (all grids were slightly off).
