/**
 * Edje example demonstrating how to use multiseat filtering.
 *
 * It presents 4 widgets that can be controlled by:
 *   * seat1 only
 *   * seat2 only
 *   * seat1 + seat2
 *   * any seat
 *
 * You'll need at least one Evas engine built for it (excluding the
 * buffer one) that supports multiseat. It may be wayland or
 * X11 with VNC support. Using other engines will lead you to a
 * situation where all seats are reported as the same one ("default").
