With current gtk-perl, when perl destroys a Gtk::Window, it
automatically destroys the "actual" gtk window on the GUI. I like
this feature, it's logical and useful (because it's a toplevel
widget). If we do what you suggest, then we'd need to call
$window->destroy at the user level just before perl destroys the
Gtk::Window. This is another possibility, it's possible, but I
personally don't like it, I prefer it inside gtk2-perl, it's more
clean and more logical for the gtk2-perl users IMHO.

Also, don't forget the problem of destructing structs (GdkColor
etc) which we explicetely malloc. We need to free them, gtk won't
do that of course, since it doesn't even know about it except
when these structs are used to pass information to functions.

Yep that was my preferred point when discussing about the GObject
hierarchy (point '2').
