Yeah, the GMainContext state diagram is a bit abstract without more
explanation. So I've replaced it by another schema, which is really
straightforward to understand now.

The "redraw" part is specific to GTK+ or a graphical application, so
it's better to not mention it in the GLib section. I explain a bit later
that it can be used to write daemons.

Thanks for your feedback,
