A bug has been fixed when doing nearest neighbour 2D interpolation. The GRIB plugin can now handle non-square cells (by resampling the domain). The cellsize and geolocalization in NetCDF are now handled the same way as in GRIB: the error is minimized in the center of the domain and the llcorner is back-calculated. Therefore very large domains are handled better. The first elements for supporting ECMWF grids have been implemented, the DEMs can now be read (but their remain as geopotential instead of height).
