    Prepopulate category grid
    
    Show empty tiles in the category page as well, and replace them
    with the real thing when available. We use the size of the
    category to know how many empty tiles to put there.
    
    At the same time, show all non-empty subcategories. An arbitrary
    minimum size does not really make sense, and we always want to
    show the featured category which may be smaller than 4.
