    Bug 771895 - add 128x128 and 256x256 versions for "folder" icon.
    
    Freedesktop's "Thumbnail Managing Standard" defines 2 standard sizes
    for thumbnails: 128x128 and 256x256 (section 5.3. Thumbnail Size).
    Since the "folder" icon is used in-place of thumbnail when selecting a
    folder in the GTK+ file dialog, it should also provide these default
    sizes.
