Thank you, I could integrate this into my slur editing (helper)
interface. Attached you can see how the handles to the second and third
control points are prolonged by a dashed line. This actually makes
editing easier because the length of this handle (i.e. the distance from
the end points to the neighboring control points) is defined as the
ratio to the baseline. Seeing the "1" unit as a dashed line makes it
much easier to judge what value to try next.
