[vtkusers] vtkInteractorStyleImage.js and center mouse down

[Rick Frank]

Thanks.


This event list seems to be missing


const START_INTERACTION_EVENT = { type: 'StartInteractionEvent' };
const INTERACTION_EVENT = { type: 'InteractionEvent' };
const END_INTERACTION_EVENT = { type: 'EndInteractionEvent' };


and so function vtkInteractorObserver::subscribeToEvents() {)

doesn't get them.

I think this is a bug, or am I missing something?

I'm trying to create an interactor observer and I can get the 
interaction events....


Thanks

Rick
