Summary0015822: OS X mouse wheel inertia / momentum makes 3D preview / ParaView become unresponsive
DescriptionOn OS X mouse wheel has inertia / momentum when scrolling / zooming. There's no typical mouse wheel, but rather touch area on Apple's Magic Mouse. Swiping with finger causes underlying view receive scroll momentum.

Currently ParaView (and probably all VTK based views) choke on such events on OS X. Where normal panning works well, using zoom via Apple's mouse swipe causes app to become unresponsive for several seconds when viewing some non-trivial data, and usually needs to be killed by the user.

This makes using ParaView on OS X really painful experience.

Please see attached video showing the random behavior of mouse wheel on some volumetric data:

1. First part using outline view, I am swiping my finger up, but rather than zooming in the outline starts to zoom then zooms out, making the behavior unpredictable

2. Using volumetric view you can see similar behavior but the zooming is far less smooth. Note this is really low zoom & low density data. Using higher zoom causes ParaView to become seriously unresponsive.


As a workaround please at least provide as soon as possible option to disable zooming by wheel, so we won't accidentally hang ParaView.

 I think I see this on my Mac. Macbook pro. Zooming acts differently depending on whether I slide two fingers up and down the trackpad or push down hard and slide two fingers up and down the trackpad.
