Re: Vertical spacing tweaks.

Hi Han-Wen,

I'm almost certainly down for EUR 130 but first I have two questions;
they're in-line:

First question: how do these two features differ? If feature #1 lets
you specify spacing details immediately after (or before?) a \break or
\pageBreak, then doesn't that give 100% control over vertical spacing
to the user (thereby making feature #2 unnecessary)? Or perhaps #2
adds some additional control above and beyond #1?

Second question: would this feature #3 be any different than making
the contents of breakLayout into a Voice added to any of the existing
Staves in the score? For example:

\score {
  <<
    \new Staff <<
        \myRealMusic
        \breakLayout
    >>
    \new Staff \moreMusic
    \new Staff \yetMoreMusic
   ... etc ...
  >>
}

Might this solution work without the need for development? (This is
stolen from Jan's input for Satie's "Petite ouverture à danser".)
