Tweaking slurs and similar curves is a matter of trial and error, although  
David's functions that expect offsets instead of hardcoded control-points  
greatly simplify it.

It would be a really valuable feature if one could let LilyPond display the  
control-points of a bezier curve.
I would imagine something like a cross or a point at the middle two  
control-points.

It should be settable through e.g.
   \paper { display-control-points = ##t }
(like annotate-spacing)
