   8 Slurs can be made with complex dash patterns by defining
   9 the @code{dash-definition} property.  @code{dash-definition}
  10 is a list of @code{dash-elements}.  A @code{dash-element} is a
  11 list of parameters defining the dash behavior for a segment of
  12 the slur.
  13
  14 The slur is defined in terms of the bezier parameter t
  15 which ranges from 0
  16 at the left end of the slur to 1 at the right end of the slur.
  17 @code{dash-element} is a list @code{(start-t stop-t dash-fraction
  18 dash-period)}.  The region of the slur from @code{start-t} to
  19 @code{stop-t} will have a fraction @code{dash-fraction}
  20 of each @code{dash-period} black.  @code{dash-period} is
  21 defined in terms of staff spaces.  @code{dash-fraction} is
  22 set to 1 for a solid slur.
