Parameters
trimPointTrim start point or end point to this coordinate.
clickPointPoint that was clicked by user.
extendTrue if the shape is to be extended. Used for polylines to determine that the last segment has to be trimmed even if another segment was clicked.

Reimplemented from RSpline.

Parameters
trimPointTrim start point or end point to this coordinate.
clickPointPoint that was clicked by user.
