set_modal() is essentially "gtk_grab when the window
is shown, ungrab when it is hidden." 

There are a few extra tweaks based on the modal flag -- e.g.,
if you call gtk_window_set_modal() on a GtkFileSelection 
object, it will properly make child dialogs modal sa well.

Note that every widget displayed on the screen must have
a GtkWindow as the toplevel widget on the heirarchy 
or GTK+ will not work correctly.
