so i should try gtk_widget_shape_combine_mask () to prevent the lower
widget exposure influencing the upper one...
how can i combine two masks? how can i invert one?
i just can't find methods for that at
http://developer.gnome.org/doc/API/gtk/index.html
so i would combine the inverted mask of the upper window with
the lower ones mask. finally modifying the lower windows shape
by the resulting mask should do the trick, shouldn't it?
