Normalized RGBA extended OBB line color (four channels, 0..1). Defaults to orange (#ff8000).
Draw a thin wireframe around each selected, visible object's extended oriented bounding box. Independent of face/edge highlighting, including NoneSelectionVisualization. Defaults to false. Reapply with setSelectionVisualization after changing this flag or the color.
No face or object-edge highlighting. Extended OBB highlighting can still be enabled independently.
