gnuplot EPS uses a vector graphics format, so the resolution is
infinite (as best as possible). Your EPS viewer may give you a different
impression (depending on whether it uses anti-aliasing). Just print the
result on a printer and you'll be convinced.

I think there's no specific key for this in the menu -- a good option
for a future enhancement (the GIF button just doesn't work if gnuplot/gd
does not support GIFs). The natural way to go is to save gstat's gnuplot
command (key: 'g'), and add

set term png
set output 'variogram.png'

to the top of this file, then run gnuplot on this file.
