Hi all,
(Happy New Year!)
Is there a logical reason that for most tweaks negative extra-offset values
move the associated grob vertically lower on the page, but with
NonMusicalPaperColumn.line-break-system-details it moves the associated system
*higher* on the page?
I offer it would be better if extra-offset had a consistent behaviour/effect.
Within a system, positive Y offsets move higher because
that is how we humans tend to think. However, page spacing
all works with Y offsets going down. That might be a little
more convenient a convention because systems are placed with
increasing Y offsets. It's easy to fix the direction of the
Y part of paper systems' extra-offsets ...

... but it is trickier to design a convert-ly rule to
