    filediff: Remove old invalidate/process code for Linkmaps
    
    This used to exist to give nicer scrolling behaviour to synchronise
    Linkmap updates with the scrolling of the ScrolledWindow. Now, it just
    imposes a massive performance penalty and doesn't seem to really
    improve matters.
