Actually, the correct way to do it is to draw the dashed slur as a series of
bezier sandwiches (and that's why the bezier sandwich code has the lineto
command in it).  We don't need to have the same points at the end of the top
and bottom beziers; they can differ.

The trick is to take the top and bottom beziers and subdivide them.

I'm currently working on a patch for this.
