Summary0004388: Improve markups fiducial label apperance in slice views

The quality of text labels of markups fiducials is not optimal, the text is not anti-aliased.

The problem is that the text is rendered using polygonal data (vtkVectorText, in vtkOrientedPolygonalHandleRepresentation3D) and by default there is no anti-aliasing of poldata in render windows.

A solution would be to use a different representation of vtkSeedWidget in slice views, where the text of each handle is rendered using vtkTextActor (the same way as text is rendered in ruler and other widgets).

TagsNo tags attached.

Note in the attached image that the ruler's "10 cm" label has a nice, smooth edge, while the markup's "F-4" label has a jagged edge.
