A ClutterBehaviourRotate rotate actors between a starting and ending angle on a given axis.
The ClutterBehaviourRotate is available since version 0.4.

ClutterBehaviour* clutter_behaviour_rotate_new (ClutterAlpha *alpha, ClutterRotateAxis axis, ClutterRotateDirection direction, gdouble angle_begin, gdouble angle_end);
Creates a new ClutterBehaviourRotate. This behaviour will rotate actors
bound to it on axis
, following direction
, between angle_begin
and
angle_end
.
