I take that back. There's a bit of logic in Viewport that calls the 
render() method on each mouse move already, likely because picking 
could initiate something that would require a re-rendering of the scene 
(for instance if the user changes an object's color on an hover event). 
I think I'll just leave it as is for now, even though there is a 
performance impact this way.
