The only problem with that change is that for the GtkObject class, __o
gets translated to _GtkObject__o, while for GtkWidget it changes to
_GtkWidget__o. I want that attribute to be accesible from descendents of
the class and other functions that know about accessing the _o attribute.
Because of this, the double underscore is not a good idea for this.
