I'm wondering how code such as this should be ported (I'm porting a
similar gtkmm example):
http://git.gnome.org/browse/gtk+/tree/gtk/gtkcellrenderertoggle.c#n325

The old gtk_paint_*(GtkStyle*,) functions took a GtkStateType parameter,
which is presumably deprecated in favour of GtkStateFlags, though that's
not documented.

But the new gtk_render_*(GtkStyleContext*, ) functions don't have a
state parameter, because GtkStyleContext has a state instead. But then
what happens to the state logic in that code?
