[vtkusers] vtkInteractorStyleImage.js and center mouse down

It's a UI decoupling model - view kind of thing....
in our interactorStyleSlice subclass, we want to update the slice number
on the UI.
This means setting the text in the div element, which we don't want to
expose directly in the interactor.
So, when the observer gets the interaction event on a mouse wheel, it
then brokers to the UI to update the current slice by fetching the
current slice from the data model....
I was able to fix it by adding
....................
'Move3D',
'StartInteractionEvent',
'InteractionEvent',
'EndInteractionEvent',
to the end of the events and then calling
viewportData.pluginData.observer =
VTKUtils.ohifInteractorObserver.newInstance();
viewportData.pluginData.observer.setInteractor(ourSliceInteractorStyle);
viewportData.pluginData.observer.setEnabled(1);
and now my observer gets the events.
I can push that change and do a pull request if you think that's the
correct fix.
Thanks
Rick
