 Examples of Usage
 -----------------

+An illustration of **Move one control point** method. Here, black is the
+original curve; dark blue is it's control polygon; light blue point is the
+point at T parameter on the original curve. Green is the resulting curve, and
+big green point is the resulting point. In this case, only control point number
+7 is moved.

+
+An example of **Adjust one weight** method. Here, the blue point is moved
+towards the control point number 8. Curve control points are not moved, only
+one curve weight is changed.

+
+An example of **Adjust two weights** method. Here, the blue point is pushed
+away from control polygon leg between control points 4 and 5 (note the negative
+value of Distance parameter). Again, control points are not moved, only weights
+are changed.

+
+An example of **Move control points** method. Here, the blue point is moved by
+specified vector by moving of three control points (6, 7 and 8).

+
+An example of **Insert knot** method. The point is moved by inserting a knot,
+thus creating additional control points, and moving three control points.
