Furthermore, as the "size-request" signal will be removed it's
important to use gtk_widget_set_size_request() for inline modifications
to widget's size requests instead of handling the signal.
I've just added another runtime warning which will fire if any
handlers are connected to a widget's "size-request" signal
at request time.
