// NB: This implementation does *not* work with every X11 window manager.
//     Currently only GNOME 1.2 and KDE 1,2,3 methods are implemented.
//
//     FIXME: implement:
//               - GNOME 2 support (see www.freedesktop.org for specification;
//                 KDE 3 uses this method as well, even though legacy KDE
//                 method we implement works as well)
//               - IceWM and XFCE support (?)
//
//     Thanks to Ian Campbell, author of XMMS Status Docklet, for publishing
//     KDE and GNOME 1.2 methods.
