OK.  This is what I thought, based on my reading of the code (it
looked like all the drawing was done in one routine, regardless of
USE_GTK), but as I said I'm just not very experienced with X and GTK

I will try to insert my code in handle_one_xevent and x_focus_changed
and report back (with a patch, I hope!).  Thank you very much for the
help.
