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. Each half-extent grows by 1% of the longest full side, preserving orientation and center, including for planar objects. Objects without a non-empty OBB are skipped. Boxes follow model placement and remain visible through occluders and section planes. Cached instance buffers use one draw per model/layer; color and camera changes do not rebuild them. Reapply with setSelectionVisualization after changing this flag or the color.
