Research direction

Run the linked Sandcastle Star Burst demo and reproduce the polyline rendering problem in 2D and CV modes, using 3D mode as the correct baseline. Trace the rendering path involved in these modes and verify that expanded star-burst polylines render correctly without regressing 3D behavior.
