I hope you're right...

Well, for instance, I want to copy a selection to a new layer. In that case, I 
don't want to do more work than necessary, so I want the copy iterator to be 
no bigger than the bounding box. 

Same with rotation: a selection should be rotating around the centre of the 
exact bounding box of the selection.

With histograms, ditto -- the exact bounding box of the selection (which 
should be contained within the paint device, I don't see any reason for a 
selection to be bigger than the paint device, but I may well miss the point 
here) is necessary to do as little work as possible.
