| Date: | Thu, 14 Jan 2016 21:06:02 +0000 |
Just for the record, I experimented with setting top-system-spacing to 0 in the "one-line-auto-height-breaking.cc" file like so:
book_->paper_->set_variable (ly_symbol2scm ("top-system-spacing"), scm_from_int (0));
But this had no effect as far as I could tell. (Perhaps top-system-spacing is given a value later and any changes made here are overwritten?)
To illustrate what happens with top-system-spacing, attached are a couple of images with all margins set to 1. One shows leaving top-system-spacing unchanged (which pushes the music down so it falls off the bottom of the page) and one shows it set to 0 (so that the music is centered vertically between the top and bottom margins).
I assume that for many use cases, top-system-spacing will need to be set to 0, so I included a note about that in the documentation.
