Q: Did something happen to font sizes?

[David Petrou]

I start off my ly files with:

    \paper { papersize = "letter" }
    \include "paper16.ly"

This would get me a font size that looked right to me.  (It gave me
something pretty identical to Dover editions of Bach.)

To my profound irritation, printing scores on my new iMac makes things
slightly smaller as if the opposite of a magnifying glass were used.
I haven't done enough testing to tell if the problem is in printing
from the pdf file instead of directly from the postscript file like
how I used to print on my unix machine, or if the problem is in the
driver that converts the graphics into a format my old non-postscript
printer can understand.

Anyway, to make a long story short, I decided to try the next higher
size: paper19.  On two machines, running 1.6.6. and 1.6.5, I get this
error:

Trying to salvage the rest.

any ideas?
