#### spanner-interface

Some objects are horizontally spanned between objects. For example, slur, beam, tie, etc. These grobs form a subtype called `Spanner`. All spanners have two span-points (these must be `Item` objects), one on the left and one on the right. The left bound is also the X-reference point of the spanner.

##### User settable properties:

`minimum-length` (dimension, in staff space)
  Try to make a spanner at least this long. This requires an appropriate routine for the `spacing-procedure` property.

This grob interface is used in the following graphical objects: Beam, ClusterSpanner, DynamicLineSpanner, Glissando, Hairpin, HorizontalBracket, LigatureBracket, LyricExtender, LyricHyphen, MeasureGrouping, MultiMeasureRestNumber, MultiMeasureRestText, OttavaBracket, PercentRepeat, PhrasingSlur, PianoPedalBracket, RemoveEmptyVerticalGroup, SeparatingGroupSpanner, Slur, SostenutoPedalLineSpanner, SpacingSpanner, StaffSymbol, SustainPedalLineSpanner, System, SystemStartBar, SystemStartBracket, TextSpanner, Tie, TieColumn, TupletBracket, UnaCordaPedalLineSpanner, VerticalAlignment, VerticalAxisGroup, VoiceFollower and VoltaBracket
