mouse wheel interaction problems

Just reporting two issues I'm struggeling with, when interacting with the widget using the mouse wheel.

1. My Logitech mouse wheel has "click-stops". When zooming a volume rendering with itk, the amount of zooming between two click stops is way too large. (I need to check whether I can change sensitivity in the driver, however the sensitivity is just fine for all other software).
2. When scrolling through a jupyter notebook with the mouse wheel, the itk-widget "catches" the callback from the web-browser page scroll and starts zooming. This can be very annoying as one may be losing a carefully chosen viewpoint and/or produce a lot of lag. The behaviour depends on the exact position of the mouse cursor within the page.

I somehow have a feeling that there is no easy solution for these usability problems, but I didn't see them mentioned in any issue and thought they may be worth documenting.
