IMHO, importing EPSG axis order mess in raster space would seem to be foolish to me 
and cause major annoyances. Performance-wise, processing flipped rasters with classic 
algorithms that process line per line would be terrible as soon as they are large enough, 
since reading each line would in practice require to read the whole raster each time.
