[tex-live] dvips from texlive2012 messes up with postscript figure

[George N. White III]

I can reproduce the problem using both evince and okular viewers with a PS
file created using dvips from TL2012 on Ubuntu 12.04 (x86_64).  The figure
looks correct in a PS file created using the distro texlive 2009 package.
It could be significant that the problem files are much larger due to the
inclusion of URW fonts.   This raises the possibility that the two files
are being rendered using different versions of the URW fonts (e.g., the
"system" versions from the linux distro and the TL version).

I recall some discussion of whether the URW fonts should be embedded in
dvips output to help
ensure that the versions used to create the PS file were the same as those
used to view the file.
Since the figure does not include the fonts, the TL2012 version may be
getting fonts different from those used to create the figure.  The
discussion in Paul Murrell and Brian Ripley (2006) Non-standard fonts in
PostScript and PDF graphics. *R News*, 6(2):41–47.
http://cran.r-project.org/doc/Rnews/Rnews_2006-2.pdf might be relevant.

I renamed the original plot and ran (using R)

> embedFonts('plot_dY_SpT_zmh_nofonts.ps', outfile='plot_dY_SpT_zmh.ps')

With this change, the output using dvips from TL2012 shows the correct
labels, but rendering quality is poor because the "embedFonts" replaces
outline fonts with the outline paths.
