    Bug 778896 - Make effective use of gexiv2 to remove the orientation
    
    Usually, it is enough to reset the Exif.Image.Orientation and
    Xmp.tiff.Orientation tags to neutralize the orientation of an image.
    However, some cameras may use non-standard tags. In such cases, merely
    setting the standard tags will make the metadata inconsistent. Hence,
    it is better to use gexiv2_metadata_set_orientation because it will
    take care of the non-standard tags.
