Toggles line wrapping within the #GtkLabel widget. %TRUE makes it break
lines if text exceeds the widget’s size. %FALSE lets the text get cut off
by the edge of the widget if it exceeds the widget size.
Note that setting line wrapping to %TRUE does not make the label
wrap at its parent container’s width, because GTK+ widgets
conceptually can’t make their requisition depend on the parent
container’s size. For a label that wraps at a specific position,
set the label’s width using gtk_widget_set_size_request().
