(viz): use real 2D circles/discs instead of spheres to display fiducials
Description
Today, we display our fiducials using 3D spheres or cubes. This works decently, but it is inefficient and limited, especially for 2D views.
Proposal
- Use 2D circles/discs/rects instead of spheres and cubes.
- Use a different shading when
- a negato slice hides the landmark
- the landmark is selected
- Provide a filling mode that allows to display a filled shape or only the contour
