Disable changing tab via scrolling
We have a few tabs in PeTrack, e.g. 2D vs 3D extrinsics. They can accidentally be changed via scrolling, which leads to wrong results. Ideally what tab is selected wouldn't change functionality. But as long as it does, we need to reduce the likelihood of error.
We probably should just disable the scrolling like we did for spinboxes.
