[gtk+/wip/matthiasc/kill-event-signals: 113/130] Drop gtk_widget_hide_on_delete

[Matthias Clasen <matthiasc src gnome org>]

commit 75cd364aa7553e55c51316fccd3d3e12e4289f98

    Drop gtk_widget_hide_on_delete
    
    This function is misnamed - it is only ever relevant for
    windows. And with the ::hide-on-delete property , it is
    no longer necessary to use the signal for this simple case.

-/**
- * gtk_widget_hide_on_delete:
- * @widget: a #GtkWidget
- *
- * Utility function; intended to be connected to the #GtkWidget::delete-event
- * signal on a #GtkWindow. The function calls gtk_widget_hide() on its
- * argument, then returns %TRUE. If connected to ::delete-event, the
- * result is that clicking the close button for a window (on the
- * window frame, top right corner usually) will hide but not destroy
- * the window. By default, GTK+ destroys windows when ::delete-event
- * is received.
- *
- * Returns: %TRUE
