    background: Force bigger size for preview rendering
    
    The current code would use the "default" cell renderer size of
    16 before scaling the emblem. Make the default size bigger so that
    the emblems are applied on that bigger size, not on the smaller size.
    
    Fixes tiny emblem for slideshows.
