Nope, but it would probably be useful.

The interface might be something like:

	UpdateLinePoint(line, pointN, point);
	InsertLinePoint(line, pointN, point); -- add before pointN
	AppendLinePoint(line, pointN, point); -- add after pointN
	DeleteLinePoint(line, pointN, point);

Similar editing functions would be nice to have for
polygons as well.

Comments ? Volunteers ? Founders ?
