[Gnuplot-py-users] hardcopy termdef defnition for pdf

I added the code below to termdefs.py to allow hardcopy
to work with pdf.  However, I found that to get printout
without an interactive session, I was better off just sending
the appropriate commands to gnuplot and going around hardcopy.
Note that I am using cygwin but with a compiled version of
gnuplot for X11.

I also found that the temporary file was being removed before
the gnuplot process was done with it.  Adding a sleep() of a
few seconds made it work but that was kind of a kludge.
Adding a g.gnuplot.gnuplot.close() worked fine since it
causes a wait for the popen() process to exit (if not using
inline).  I wonder if there is some way to put this into
the __del__() function at a place where this would happen
naturally?  I tried the obvious on Gnuplot but it didn't work.
