    ui: Make the collection icon view more compact
    
    Don't make the game thumbnails expand as the window expand but rather
    pack as much as possible in the center of the window. This avoid a weird
    accordion effect when resizing the window and avoid having to move the
    eyes as much to see the available games.
    
    Also reduce a bit the spacing of the rows and columns to make the view
    more compact.
