    Remove a note from the docs that is now obsolete
    
    Chaining up in signal handlers now correctly handles boxed objects, so this
    note about chaining up in a size-request signal handler can go.

-Note that currently signal_chain_from_overridden doesn't work from a
-size-request class closure, because the Gtk2::Requisition parameter
-you pass ends up getting copied, so changes made to it by the
