"""Provides GUI tools to stretch Draft objects.
|
|
|
|
It works with rectangles, wires, b-splines, bezier curves, and sketches.
|
|
It essentially moves the points that are located within a selection area,
|
|
while keeping other points intact. This means the lines tied by the points
|
|
that were moved are 'stretched'.
