from the CurvePolygon and all interior rings.

Removes an interior ring from the polygon. The first interior ring has index 0.

The corresponding ring is removed from the polygon and deleted. If a ring was successfully removed

the function will return true. It is not possible to remove the exterior ring using this method.
