GL widget to ship with GTK

[Jordi Rovira i Bonet <igurnebli users sourceforge net>]

Hi,

    I think it would be a good thing if the GtkGLArea widget shipped
    with the default GTK distribution, as in my oppinion, it has been
    tested a lot and is very used.
    I suppose that this is not the first time someone suggests this, but
    i haven't seen any discussion before about it.
