Slurs can be made with complex dash patterns by defining the
@code{dash-definition} property.  @code{dash-definition} is a list of
@code{dash-elements}.  A @code{dash-element} is a list of parameters
defining the dash behavior for a segment of the slur.

The slur is defined in terms of the bezier parameter t which ranges
from 0 at the left end of the slur to 1 at the right end of the slur.
@code{dash-element} is a list @code{(start-t stop-t dash-fraction
dash-period)}.  The region of the slur from @code{start-t} to
@code{stop-t} will have a fraction @code{dash-fraction} of each
@code{dash-period} black.  @code{dash-period} is defined in terms of
staff spaces.  @code{dash-fraction} is set to 1 for a solid slur.
