The ClutterBehaviourRotate struct contains only private data and should be accessed using the provided API

### clutter_behaviour_rotate_new ()

    ClutterBehaviour *  clutter_behaviour_rotate_new        (ClutterAlpha *alpha,

Creates a new ClutterBehaviourRotate. This behaviour will rotate actors bound to it on `axis`, following `direction`, between `angle_start` and `angle_end`. Angles >= 360 degrees will be clamped to the canonical interval <0, 360), if angle_start == angle_end, the behaviour will carry out a single rotation of 360 degrees.

If `alpha` is not `NULL`, the ClutterBehaviour will take ownership of the ClutterAlpha instance. In the case when `alpha` is `NULL`, it can be set later with `clutter_behaviour_set_alpha()`.

`alpha` : | a ClutterAlpha instance, or `NULL`. [allow-none]
