    panel: Move shared GCancellable code into panel class · 93b14a43
    Robert Ancell authored
    Make the panel class provide a cancellable that will be cancelled when the panel
    is destroyed. Panel implementations can use this and not have to mangage the
    cancellable themselves. Consolidate cases where panels had multiple cancellables
    that were all being used for this behaviour.
