/**
 * @brief This class is a wrapper for the org.kde.KWin D-Bus interface.
 *
 * The main purpose of this class is to be exported on the D-Bus as object /KWin.
 * It is a pure wrapper to provide the deprecated D-Bus methods which have been
 * removed from Workspace which used to implement the complete D-Bus interface.
 *
 * Nowadays the D-Bus interfaces are distributed, parts of it are exported on
 * /Compositor, parts on /Effects and parts on /KWin. The implementation in this
 * class just delegates the method calls to the actual implementation in one of the
 * three singletons.
 *
 * @author Martin Gräßlin <mgraesslin@kde.org>
 * @todo KDE5: remove the methods provided on /Effects and /Compositor
