[vtkusers] Vtk.js and scroll wheel click

[Sebastien Jourdain]

Hi Rick,

The style itself will handle all events the way you want but you will have
to define all the interactions.
The manipulators on the other hand use a manipulator style in which you can
plug a bunch of manipulators to handle specific part
(button/modifier/action).

In your case, you may have to implement a panManipulator that only deals
with the mouse wheel/pinch. You can look at the zoom one which has an
option to support the mouse wheel.

HTH,

Seb
