10.7.5 Debugging skylines

To show the skylines used for spacing, use

\override SomeGrob.show-horizontal-skylines = ##t

or

\override SomeGrob.show-vertical-skylines = ##t

The option debug-skylines is equivalent to setting show-vertical-skylines on VerticalAxisGroup and System.

Another particularly useful application is showing the skylines used for note spacing:

\layout {
  \context {
    \Score
    \override PaperColumn.show-horizontal-skylines = ##t
    \override NonMusicalPaperColumn.show-horizontal-skylines = ##t
  }
}

This is also an occasion to test if the pure estimates used to build them are reasonably accurate.
