Filling polygons using GTK-Extra.

Hello again!

I need to draw some figures in my application that will require the 
creation and
display of polygons on the screen. On the gtkplotdata.h file I found a 
few basic
shapes like, lines, rectangles and ellipses. Is there a similar function 
for general
polygons?

I tried to fill the region defined by a set of points using 
gtk_plot_data_fill_area, but
the filling is done with respect to the x-axis... I also looked at the 
gtkplotpc.h file,
but I am not sure whether or not I could use those functions into a 
canvas widget.
I checked the CVS repository, but  couldn't find a testgtkplotpc.c file 
for some
enlightening hints either. I can try it if that's the answer, but I want 
to check with
you guys first.

Any suggestion?

    Thank you,

        Fabio.
