Convert the rotation centers to be AnchorCoords

Browse Source 
Currently only the Z axis rotation center can be set using a gravity
but the other rotations also store their center as an AnchorCoord for
consistency. Specifying the center as a gravity makes less sense for
the other axes because the actors have no size along the Z axis.

The rotation angles are now stored as gdoubles and the fixed point *x
entry points have been removed.

The Z rotation can now be set with a gravity center using the
following new function:

void clutter_actor_set_z_rotation_from_gravity (ClutterActor   *self,
                                                gdouble         angle,
                                                ClutterGravity  gravity);
