    Drop gtk_widget_event from API
    
    We don't want events to be injected randomly from
    the outside. Plus, there's no way to create such
    events from the outside now.

-/**
- * gtk_widget_event:
- * @widget: a #GtkWidget
- * @event: a #GdkEvent
- *
- * Rarely-used function. This function is used to emit
- * the event signals on a widget (those signals should never
- * be emitted without using this function to do so).
- * If you want to synthesize an event though, don’t use this function;
- * instead, use gtk_main_do_event() so the event will behave as if
- * it were in the event queue.
- *
- * Returns: return from the event signal emission (%TRUE if
- *               the event was handled)
