/**
* clutter_actor_get_allocation_vertices:
* @self: A #ClutterActor
* @ancestor: (allow-none): A #ClutterActor to calculate the vertices
* against, or %NULL to use the #ClutterStage
* @verts: (out) (array fixed-size=4): return
* location for an array of 4 #graphene_point3d_t in which to store the result
*
* Calculates the transformed coordinates of the four corners of the
* actor in the plane of @ancestor. The returned vertices relate to
* the #ClutterActorBox coordinates as follows:
*
* - @verts[0] contains (x1, y1)
* - @verts[1] contains (x2, y1)
* - @verts[2] contains (x1, y2)
* - @verts[3] contains (x2, y2)
*
* If @ancestor is %NULL the ancestor will be the #ClutterStage. In
* this case, the coordinates returned will be the coordinates on
* the stage before the projection is applied. This is different from
* the behaviour of clutter_actor_get_abs_allocation_vertices().
*
* Since: 0.6
