Hi, Vladimir–

I do have a rough proposal for describing the selection of a shape 
within a geometric or geographic area, call "annoshapes" [1].

It would not deal with the case of different photographs of the same 
painting (which I think is a Hard Problem), but it does address having a 
unified viewport and coordinate system within that viewport.
