Kai,
I think it makes sense to start a discussion about what version of gnuplot will
be required by the upcoming 3.2 release and whether or not conditional support
for more recent gnuplot builds should be included.
For example, I have a local copy of gnuplot_drawnow that respects
set(gcf,"position") for the x11 terminal (both window position and size are
respected). My patch requires a very recent build of the gnuplot developers
sources (it should also work with 4.2.4+).
Regarding conditional support, this is easily done by using
__gnuplot_version__() and compare_versions().
