The ::map signal is emitted when widget is going to be mapped, that is
when the widget is visible (which is controlled with
gtk.widget.Widget.setVisible) and all its parents up to the toplevel widget
are also visible. Once the map has occurred, #GtkWidget::map-event will
be emitted.
The ::map signal can be used to determine whether a widget will be drawn,
for instance it can resume an animation that was stopped during the
emission of #GtkWidget::unmap.
