I can't resist but to add my two cents.

Ben was asking that gnuplot supports capabilities which are already
offered by a system's window manager. I think it is very useful to
be able to control, per script, the size and position of windows
opened by that script. But I agree with Ethan and others who
essentially said that gnuplot is the wrong place to add a solution
for this. The burden is on the Octave project to come up with a
cross-platform interface to the different window managers to
implement that capability. What is need from gnuplot is a way to
query the window ID or window handle of a terminal window.

On a second thought, in Matlab you can program GUIs for your
application. And one may embedd plots in a GUI. That means, you
would need the capability to render a plot in a user-provided
canvas widget. The x11 terminal currently supports this, have
you looked at the gpdemos.tcl in gnuplot's demo directory?
It seems to me, this is what you really want to do, at the end
of the day.
