One use case for star shapes is to stroke the resulting paths, animating the stroke over time to draw it out. This can look weird when the path starts from an arbitrary point on the outline of the shape.

This change allows star shapes to be created starting from either an inner or outer vertex (previously the first corner was always an outer vertex). Also, you can specify a startAngle for the cubics or path requested from the shape, where that angle is relative to the center of the shape.
