feat(viz): add touch interaction for TF window in negatoscope
Description
When running an application only with a touchscreen, we do not have any way to adjust the window level and width of the transfer function on a negatoscope.
Functional specifications
- Use the existing
WindowLevel
adaptor - In the negatoscope view, in the bottom toolbar, add a button to switch between the window level and slice selector
Technical specifications
- WindowLevel is a bit too big, in this case we would only need the top slider and not the extra buttons and info below
- We could also use an overlay instead of a line layout for the toolbar
Test plan
- Test in SightViewer
