Display 3D ortho axis in the main 3D view.
Axis are displayed in a dedicated viewport which can be placed all around the main viewport. Axis labels are displayed in a dedicated viewport with a specific camera to act as a billboarding layer. Axis labels can be changed with the mode combo box from the navigation widget.
