Implementing that is easy, of course. What I'm thinking about mostly is
the predictability of the results when anything changes, for example the
Y coordinate of either point.
What would you think of using a staff-space offset for Y (as per your
suggestion) but apply it to the vertical center between the two
endpoints? That way the whole slur should somewhat shift together with
changed Y of an end point.
Would it be acceptable to have a pair? as an argument when the two
elements *do* refer to X and Y but with completely different behaviour?
Or should that then be separated to two individual properties?
