I believe that's how we designated it, though I think we actually went
with 'interacts with the map', since controls also (for example) display
the mouse position or the scale. 

So yes, things which interact with the map are controls.

Handlers, on the other hand, interact only with events for the most
part, and pass events up to controls to interact with the map.
