Couple of remarks:

1. I've noticed that (remarkably) Undo does a very good job returning  
graphics to their prior state.

2. If you rotate a graphic manually, you can get the new viewpoint if  
you literally copy and paste the graphic itself into

                 ViewPoint /. AbsoluteOptions[    ]

There must be a better way, however.
