Well, I have no actual idea here.  I just know that stuff gets scaled
around in paper and/or layout blocks and I had a hard time figuring out
how or why.  Maybe it's different in \paper and \layout (and I think at
the very least in the \layout block of a \score markup), and maybe I
just haven't got the hang of it at all.
