nt you will want to render onto a cairo surface.
If you want to render text put it in a Pango.Layout and use

Define works :) Does it limit to what was set as maximum width chars?
When resizing does it use the available space to show mor

Am I missing something? is this the correct way to force a certain width

Yeah gnome documentation sucks.

Then have your app launch the uri relative to the docdir [2]. If you
