    # CAUTION: The order in which the image components are rendered is
    # very important. For example, in order for theme images to hold
    # the branding information the `Identity/Images/Brands' directory
    # must be rendered before the `Identity/Images/Themes' directory.
    # The reason of this is that brand images are not draw inside
    # theme design models themselves, but combined with theme images
    # using the ImageMagick tool suite once both have been rendered.

    # Update list of directories to be sure that brands will always be
    # rendered as first image component. Here we remove the brand
    # component from the list and add it explicitly on top of all
    # other directories in the list.
