Editing Making slurs with complex dash structure

Slurs can be composed of complex dash patterns by setting the <code>dash-definition</code> property, which is a list of slur segments, which in turn are lists of parameters setting up the dash behavior of the given segment.

Slur segments are defined in terms of the Bézier parameter&nbsp;<var>t</var>, which ranges from&nbsp;0 at the left end of the slur to&nbsp;1 at the right end of the slur.  A slur segment has the form <code>(<var>start-t</var> <var>stop-t</var> <var>dash-fraction</var> <var>dash-period</var>)</code>. In the segment spanning the range <var>start-t</var> to <var>stop-t</var>, the dash pattern is defined by the values of <var>dash-fraction</var> and <var>dash-period</var>. <var>dash-fraction</var> specifies how much of a dash period is black; if set to&nbsp;1 you get a solid slur segment. The unit for <var>dash-period</var> is staff spaces.
