Octave has two font paths that need to be set.

        GDFONTPATH sets the path for gdlib (bitmap canvases)

        GNUPLOT_FONTPATH sets the postscript fontpath for gnuplot

I written a m-function to construct each from info supplied by  
fontconfig. There may be a better way of doing this (I'm new to  
fontconfig).

        [GDFONTPATH, true_type_fonts] = fontpath_form_fontconf (".ttf");

        [GNUPLOT_FONTPATH, type_1_fonts] = fontpath_form_fontconf (".pfa");

My thought is to set these environment variables, for each instance of  
gnuplot, each time gnuplot_drawnow opens a plot stream.

For anyone willing to test this on their systems (Window's users are  
of greatest interest), I've attached both a changeset as well as the  
function itself.
