#### BreakAlignment

BreakAlignment objects are created by: Break_align_engraver

Standard settings:

`breakable` (boolean):
  `#t`

  Can this object appear at a line break, like clefs and bar lines?

`stacking-dir` (direction):
  `1`

  Stack objects in which direction?

`break-align-orders` (hash table):
  `'#((instrument-name left-edge ambitus breathing-sign clef staff-bar key-signature time-signature custos) (instrument-name left-edge ambitus breathing-sign clef staff-bar key-signature staff time-signature custos) (instrument-name left-edge ambitus breathing-sign clef key-signature staff-bar time-signature custos))`

  Defines the order in which prefatory matter (clefs, key signatures) appears. The format is a vector of length 3, where each element is one order for end-of-line, middle of line, and start-of-line respectively. An order is a list of symbols.

  For example, clefs are put after key signatures by setting

                	\override Score.BreakAlignment #'break-align-orders = #(make-vector  3
                	  '(span-bar
                	  breathing-sign
                	  staff-bar
                	  key
                	  clef
                	  time-signature))

`axes` (list):
  `'(0)`

  list of axis numbers. In the case of alignment grobs, this should contain only one number.

`X-extent-callback` (procedure):
  `Axis_group_interface::group_extent_callback`

  Procedure that calculates the extent of this object. If this value is set to `#f`, the object is empty in the X direction. The procedure takes a grob and axis argument, and returns a number-pair.

This object supports the following interfaces: axis-group-interface, item-interface, break-alignment-interface and grob-interface
