Highlight or Cross out measures

[Jay Anderson]

I want to be able to highlight sections (just a few measures).

Some past work:
- http://lsr.di.unimi.it/LSR/Snippet?id=699 - manual markup
  - http://lists.gnu.org/archive/html/lilypond-user/2008-09/msg00083.html
- http://lsr.di.unimi.it/LSR/Snippet?id=726 - colors whole staff

Has there been any other work on this in the intervening years? My
other thoughts are to use analysis brackets or draw custom bar lines
to denote the sections.
