After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24.

Regardless of raw mode, the point list will be adjusted such that the first point is the lowestleftmost one and the orientation is clockwise always.
