-		Occludes light cast by a Light2D, thus casting shadows. The LightOccluder2D must be provided with a shape (see OccluderPolygon2D) that allows the shadow to be computed. This shape affects the resulting shadow, while the shape of the representating asset shadowed does not actually affect shadows.
