i gone back to Gtk.Container.Add.

it doesn't more overflow at the 4th side, and that's a good thing,
but i don't understand what's wrong with Gtk.Button.Set_Image.


i was wrong telling "too much spaces with Gtk.Button.Set_Image",
because it's not Set_Image which causes the spaces,
but it's the use of a Gtk_Image instead of a Gtk_Pixmap.

i don't understand more what's the difference between Gtk_Image and 
Gtk_Pixmap.

Gtk.Misc.Get_Padding returns 0 0.
i have no other idea now.


it's better with Add than with Set_Image,
but it's not very nice because RAPID has not exactly the same behavior 
with Gtk and with TclTk.
(2*4 pixels in a small button (27 pixels) is a big part.)

i cannot revert to Gtk_Pixmap because it is Obsolescent.

so i still need help, please :-)
