Rotate manipulator - attaches to physical shape and draws local axes widgets - rings drawn from attached physical center, in plane defined by axis.

User can mouse over (turns yellow) and L click/drag to rotate attached physical round the ring center. Widgets use standard 3D package axes colours: X red, Y green, Z blue.
