I've written a music search tool that exports MusicXML and colors the
matching notes, and I'd like those colors to show up in LilyPond
typesetting.
There is no doubt a much more elegant way to do this, but the included
patch works for me, and it would be great to see this functionality
added to the musicxml2ly distribution.
