Re: EOG features

[Stanislav Brabec <sbrabec suse cz>]

My opinion:

- Keep the rotate button.

- Change menu item from "Rotate..." to "View rotated..." to prevent
  confusion.

- Never implement auto-save without prompt. Eog is a viewer, not editor,
  and overwriting of original image would be a bad surprise.

And optionally:

- If user rotates image, Save rotation state to a special place and use
  it for next open (preferably shared with other applications).

- Add menu item "Reset rotation"

Details and rationale:

At least with my camera (Minolta DiMAGE A1), this operation irreparably
breaks EXIF MakerNote and destroys mid-size preview. It disallows to
view such image back in the camera and loses special image information.

For images, with size not dividable by 16, lossless rotation is
impossible.

Additionally, I have all original images write protected, but have to
rotate them to view, because EOG does not yet respect EXIF.
