OptionalrotationRotation DOF (degrees). Default range -180..180.
OptionaltranslationTranslation DOF (length). Default range 0..100, matching prismaticJoint
(both model a slide along an axis). This is deliberately asymmetric with
planarJoint's in-plane translations, which default to -100..100 because
an unanchored in-plane slide is naturally bidirectional.
Per-DOF ranges for a cylindrical joint (rotation about + slide along one axis).
