§113 "velocity vectors": one segment per body from its transform origin along
its linear velocity, optionally a second along its angular velocity.
Reads forEachBody → getBodyTransform + getBodyVelocities (+
isBodySleeping when skipSleeping is set), so the segments come out in
ascending body id — the §33 order, which makes an overlay's line list
reproducible run to run.
