As far as I can see, there is a gradual overhead of C libraries involved here. The Platform could ship the following subsets of Gtk2Hs:

cairo cairo+glib+pango cairo+glib+pango+gio cairo+glib+pango+gio+gtk

It's a question of how big the tar ball is and how much work it is to bundle the C libraries with the Platform.

Cheers,

That's why I voted for including just cairo.

it's low overhead, high quality and gives your haskell install access to cross-platform graphics capability.

How useful is cairo without pango?

Good question ! Fonts are still available even without pango, for example freetype fonts are supported. I think there are limitations but I can't remember exactly what. I've been down this road before, and I think that for basic use your good-to-go without pango as long as you don't want to run your text along a spiral path, or something like that. What I can't remember and what some of my example code doesn't reveal, is whether text rotation is possible. As long as you can scale and rotate cairo withot pango would be ok, right ? Brian
