    ListView: Remove CanvasItem warnings by acting like CanvasHost
    
    Calls to Invalidate ColumnCellRating and ColumnCellCheckBox would cause
    CanvasItem warnings to be emitted because those items were never
    assigned a CanvasManager. This patch makes ListView act more like a
    CanvasHost in assigning a CanvasManager to each CanvasItem. Fixes
    bgo#638475.
