[Gtk-sharp-list] Interline in a label

[Julien Sobrier]

Hello,
how could I change the interline in a multi-line label? It looks like I
have to use the Pango.Layout.Spacing property. But I could only find
examples where I have to override the ExposeEvent method of a widget.
This seem overkill just to change the interline. I did not find out how
to apply a new custom Pango.Layout to a Label. Any idea?

Thank you
Julien
