#### Arpeggio

Arpeggio objects are created by: Arpeggio_engraver and Span_arpeggio_engraver

Standard settings:

`X-extent-callback` (procedure):
  `Arpeggio::width_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.

`Y-extent-callback` (procedure):
  `#f`

  see `X-extent-callback`.

`print-function` (procedure):
  `Arpeggio::print`

  Function taking grob as argument, returning a `Stencil` object.

`Y-offset-callbacks` (list):
  `'(#<primitive-procedure Staff_symbol_referencer::callback>)`

  see `X-offset-callbacks`.

`X-offset-callbacks` (list):
  `'(#<primitive-procedure Side_position_interface::aligned_side>)`

  A list of functions determining this objects' position relative to its parent. The last one in the list is called first. The functions take a grob and axis argument.

`direction` (direction):
  `-1`

  Up or down, left or right?

`padding` (dimension, in staff space):
  `0.5`

  Add this much extra space between objects that are next to each other.

`staff-position` (number):
  `0.0`

  Vertical position, measured in half staff spaces, counted from the middle line.

This object supports the following interfaces: font-interface, item-interface, side-position-interface, staff-symbol-referencer-interface, arpeggio-interface and grob-interface
