Attached below are two screenshots made in my system.  I deliberately
decreased the size of the windows to save bandwith.  screenshot1.png is from
gv while viewing the first page of test.ps with magnification of 200% and
antialiasing on.  The characters look fine for me.  screenshot1.png is from
xpdf while viewing part of the figure at 400%.  At that magnification, we
see the difference of line widths.  At 200% the lines do seem to have the
same width.  Do you confirm these results in your system?

Unstable here.  I have gv_3.6.1-4.

See above.

Mine is also 1024x768.
