writing 'mouse interactive' routines to extend draw, plot2d, etc.

Yes, this is just what I had in mind when I wrote about a re-draw 
function in my last post. The idea is to declare the new settings in a 
more intuitive style, following draw's syntax, and call gnuplot_replot 
internally. One of the targets of the draw package is to make it 
possible to learn plotting with only the Maxima manual at hand, so that 
the common Maxima user is not obliged to read also the Gnuplot manual.
