New issue 2827 by [email protected]: Add documentation in the Notation
Manual about invisible grobs
http://code.google.com/p/lilypond/issues/detail?id=2827
There are, in general, two types of invisible grobs in LilyPond:
1) "Container" grobs that help a set of grobs (usually in a list
called "elements") align themselves.
2) "Blocking" grobs that shadow another grob (SpanBarStub to SpanBar, for
example) or a group of grobs (LeftEdge to other stuff in a
NonMusicalPaperColumn, for example) and block them from moving in a certain
direction.
These are potentially problematic for users because they are unseen and
therefore it is difficult to know how they work and how overrides relate to
both them and the grobs with which they interact.
A section in the NR about these grobs should created, preferentially by
someone who actually understands the art of documentation writing.
