But only if you hit Undo immediately after doing the rotation. And if
you rotate it, let go of the mouse, and rotate some more, Undo only
takes you back to where it was before the most recent rotation, not back
to the original state when the graphic was first created.
I just find it a bit inconsistent that re-executing a graphic does *not*
change it back to the state specified in the input; most everything else
does revert back, even a Manipulate.

Oh, OK...or even {ViewPoint,ViewVertical} /. AbsoluteOptions[ ]
(sometimes the ViewVertical gets changed too). Still...

I agree that there *should* be a better way.
