[Haskell-cafe] gtk2hs, TreeView and CellRenderer

As far as I can tell, there is not way to create CellRenderer that could include icons with the text (I think it is because of incompatibilities of Haskell type classes and Gtk inheritance hierarchy). Is it a good way to use CellRendererPixbuf and render to pixbufs using Cairo? I think my TreeView hierarchies won't be very big, around 1000 items for a while.
