We have the field orientation in ImageInformation. Value is the enum from
libkexiv2. The orientation exif flag is read to the db when scanning images
but it is used nowhere to actually rotate the image.
Shouldnt this db flag be kept in sync with the image metadata in all
situations? At least, when we can write to the file.
