PangoContext with the appropriate font map, font description,
and base direction for this widget. Unlike the context returned
by gtk_widget_create_pango_context(), this context is owned by

match any changes to the widget’s attributes. This can be tracked
by using the
GtkWidget::screen-changed signal on the widget.
