Well, by "rotated 45 degrees" I just mean rotated by tilting the camera. And why would it need a lot of code change? Maybe I'm overlooking lots of problems here, but isn't it just a matter of discarding the EXIF rotation (or applying a rotation to the image data before exposing it to the Hugin core) and replacing it with a roll of 90 or 270 degrees upon loading the image (which would also happen when loading images without EXIF information)? Of course the HFOV field will then sometimes be a VFOV really, but the same is true when holding the camera at a 45 degree roll: strictly the HFOV won't be "horizontal" then.
