I am rather sure that it does not use any features newer than PDF-1.4. My
Patch #1023783, Write username to pdf and ps plots and fix both terminals,
solves this problem. It uses the current PDFlib syntax if available and
sets PDF to compatibility level 1.4. And it solves some more problems. For
example, original gnuplot states in every plot that the author of this
plot was Hans-Bernhard Broeker, in the official version.  This of course
is not the correct way to handle it. The patch tries to find out the name
of the current user and uses this one. Some effort is done to work with
Unix and Windows. The Windows part has to be tested since I do not have
Windows.

In addition, this patch adds information to postscript files that enable
ghostscript (and hopefully Acrobat) to set the username and title of the
plot correctly when converting the postscript file to pdf.

Please have a look at this patch. I really think it is useful. I am using
it since I have uploaded it to sf.net and I never had any problems.
