Since you noticed that, I took another look, and I think I've realized how to 
solve several problems for cheap.  Making the effective steps smaller will 
also allow negative zoom via these wheels, I think.  If it works like I 
expect.  I'll try it here shortly.

Limiting the blue wedge seems to equal allowing less rotation of the 
controller, and bringing the zoom limits in.  Is this right?

I experimented with the zoom limits with the idea to allow just a little more 
than anything I would consider useful.  This way it doesn't leave you wishing 
it would go a little higher or lower, and in particular it does not go so high 
that the window starts growing.  (A problem Yves wanted to solve.)  I think 
leaving a little more range than is in good taste is acceptable, because users 
don't have to zoom that far if they don't want to.

Let me know if I do not understand your point though.
