I have noticed that apparently the most convenient method
to create graph structure (object of type GraphImage) is
to use 'draw' and them 'getGraph'. Unfortunately, 'draw'
presents graph on the screen regardless of need -- even
if all we need is a GraphImage ws still get graph on the screen.
I am thinking about modifying draw, strictly speaking adding
a now option called for example 'nodraw' which when set will
inhibit drawing. This would allow getting a GraphImage
using 'draw' without any trace on the screen.
I started thinking about this because of GnuDraw package.
'gnuDraw' procuces a file and makes graph on the screen.
But if we want file, then graph on the screen seem
redundant, so the new option would avoid it. More
precisely, I would like to add new option to the call
of 'draw' inside of 'GunDraw'.
