Re: Getting Y-offset on systems to be exact on left and right "mirrored pages"

[Owain Evans]

That is totally fantastic! Works perfectly!
I've one variable / context defining both left and right pages: system 
in-between distance and bars per system. 
And will just add another context if I need to use the Y-offset of 
NonMusicalPaperColumn which will be unlikely.

Many thanks,
Owain
