Looks like Jurgen is on vacation or on a long weekend...
I changed slightly the source of Plot_gtk.cc to fix the problem. Only 3 lines
modified.

seems to solve the problem and scale well with point_size.

I understand my previous report was very unclear. Trying to describe a visual
thing in english words while you're speaking french is not obvious,
so I included a snapshot of the plotted window and I will describe the really
small problems I see.
1) the square and the diamond are way too large, they should display the same
size as the up triangle and the down triangle, no more.
2) it is obvious that the square is displayed UNDER the line in contrary of
all other symbols who are right on the line.
