C3D-0430 · V-DWY: two edge polylines down the driveway (no cross-lines) [C3D-DWY4] done

Replaces the earlier V-DWY runs with two polylines - the left and right driveway edges each running the length of the corridor (points ordered along the run, split by side), so no line cuts across the driveway. Left edge clean; right edge has one small kink at the mid bend. Erases prior V-DWY first.
