    # `Artworks/Themes' directory.  The reason of this is that brand
    # images are not drawn inside theme design models themselves, but
    # combined with theme images using the ImageMagick tool suite once
    # they both have been rendered as PNG files.

    # production order when they are included in the list of files to
    # produce.
