Imagine someone creates some event that would modify an artist upon
picking, or do some expensive calculation, or some other action. But, I
seriously doubt anybody would want those actions to fire while using the
zoom/pan tool. Especially since the mouse cursor looks totally different. I
am curious why you would expect pick events to fire while using pan/zoom.
What is the user-story that compels that expectation? Perhaps I could be
convinced otherwise to offer some sort of toggle.
