I modified the grn code, but after I found out that groff
doesn't accept fractional values for points, e.g. \D't 0.15p'.
So if you pick the minimum linewidth equal to \D't 1p', it's way
too thick that is what you wanted to avoid in the first place.
Do you have any other unit in groff that can fractioned to make
the equivalent of 0.15p?
