Comment #3 on issue 2609 by [email protected]: Patch: get rid of minimum-[XY]-extents
http://code.google.com/p/lilypond/issues/detail?id=2609#c3
get rid of minimum-[XY]-extents they were used long ago for vertical spacing, now they are deprecated. Their only use was with DynamicTextSpanner, but it was more of an ugly hack than a real solution. http://codereview.appspot.com/6294086
