* clutter/clutter-fixed.h:
Fixed CLUTTER_ANGLE_ macros.
* clutter/clutter-behaviour-ellipse.h:
* clutter/clutter-behaviour-ellipse.c:
Implemented "apply" signal closer to position actor on the start
of the elliptic path.
(clutter_behaviour_ellipse_get_angle_begin):
(clutter_behaviour_ellipse_set_angle_begin):
(clutter_behaviour_ellipse_get_angle_end):
(clutter_behaviour_ellipse_set_angle_end):
(clutter_behaviour_ellipse_get_angle_tilt):
(clutter_behaviour_ellipse_set_angle_tilt):
Renamed with an x suffix; added versions for angles in degrees.
