    appDisplay: Increase fade offset in FolderView
    
    Just as we do in AllView, we set the offset of FolderViews' fade
    effect so that no icon is faded when a full page is visible.
    This works fine in AllView, however in the FolderView case where
    the popup's offsets eat away from the available fade height, the
    effect ends up being barely noticeable at all.
    While it is not ideal to apply the fade to the edge of a "full page",
    it looks less ugly than the current state, so pick the lesser evil ...
