    // Clipboard management
    // ************************************************************************ */
    /*
     * Before Gnome Shell 40, St API couldn't access binary data in the clipboard,
     * only text data. Also, the original Desktop Icons was a pure extension, so it
     * was limited to what Clutter and St offered. That was the reason why Nautilus
     * accepted a text format for CUT and COPY operations in the form:
     *
     *     x-special/nautilus-clipboard
     *     OPERATION
     *     FILE_URI
     *     [FILE_URI]
     *     [...]
     *
     * In Gnome Shell 40, St was enhanced and now it supports binary data; that's
     * why Nautilus migrated to a binary format identified by the atom
     * 'x-special/gnome-copied-files', where the CUT or COPY operation is shared.
     *
     * To maintain compatibility, in the past, we checked the current Gnome Shell
     * version and, based on that, set the binary or the text clipboards.
     *
     * With the newer versions of gtk4-ding, we only set the binary version and add
     * other composite providers for the plain text versions like the newer
     * Nautilus/Files.
