I've thought about it. Ultimately you'll want to crop it at some 
point or another, so I think it makes sense if there were 
operations you'd want to do on an infinite view where cropping 
will get in the way.

The library has a tiling view, which is infinite in concept but 
currently in effect it immediately crops the infinite view it 
creates.

I would probably have to rename the isView template to 
isFiniteView, and many operations expect a finite view...
