DoActivate()
Start reshaping, if FindToolHandleAt(Point, string) finds a reshape handle at the mouse down point.
Declaration
public override void DoActivate()Overrides
Remarks
If successful this sets Handle to be the reshape handle that it finds and AdornedLink to be the Link being routed. It also remembers the original link route (a list of Points) and curviness in case this tool is cancelled. And it starts a transaction.
DoCancel()
Restore the link route to be the original points and curviness and stop this tool.
Declaration
public override void DoCancel()Overrides
Reshape(Point)
Change the route of the AdornedLink by moving the point corresponding to the current Handle to be at the given Point.

This is called by DoMouseMove() and DoMouseUp() with the result of calling ComputeReshape(Point) to constrain the input point.
