I presume that what you say is that I should replace all that with Pango... Now I have some problems: first, I'm using vala and I can't find the "get_pango_layout" from a widget. It exists "create_pango_layout", so I suppose that this is the call I need to create a layout. Now the big question is: does ANY widget return the right layout, or I must use a widget designed to contain text (like a Gtk.Label) to get that layout, paint into it, and paste it in the final Cairo canvas (which won't be the same canvas than the Gtk.Label from which I created the layout)?
