A few changes to the main driver in plot.c allows one to build=20
gnuplot as a library, then one can drive gnuplot from a thread=20
within the address space of a sophisticated GUI, setting ranges=20
programmatically.  Add a list box to store command history and=20
you get a native, lightweight, in-proc replacement for ye olde=20
console.  Only hitch to this solution is (was?) the existence=20
of a few globals that in effect limit the GUI to manipulating=20
a single plot.

I hope to get back to exploring this (using wxWidgets) over=20
the Christmas period.
