// ----------------------------------------------------------------------------
// Fullscreen mode:
// ----------------------------------------------------------------------------

// NB: Setting fullscreen mode under X11 is a complicated matter. There was
//     no standard way of doing it until recently. ICCCM doesn't know the
//     concept of fullscreen windows and the only way to make a window
//     fullscreen is to remove decorations, resize it to cover entire screen
//     and set WIN_LAYER_ABOVE_DOCK.
//
//     This doesn't always work, though. Specifically, at least kwin from
//     KDE 3 ignores the hint. The only way to make kwin accept our request
//     is to emulate the way Qt does it. That is, unmap the window, set
//     _NET_WM_WINDOW_TYPE to _KDE_NET_WM_WINDOW_TYPE_OVERRIDE (KDE extension),
//     add _NET_WM_STATE_STAYS_ON_TOP (ditto) to _NET_WM_STATE and map
//     the window again.
//
//     Version 1.2 of Window Manager Specification (aka wm-spec aka
//     Extended Window Manager Hints) introduced _NET_WM_STATE_FULLSCREEN
//     window state which provides cleanest and simplest possible way of
//     making a window fullscreen. WM-spec is a de-facto standard adopted
//     by GNOME and KDE folks, but _NET_WM_STATE_FULLSCREEN isn't yet widely
//     supported. As of January 2003, only GNOME 2's default WM Metacity
//     implements, KDE will support it from version 3.2. At toolkits level,
//     GTK+ >= 2.1.2 uses it as the only method of making windows fullscreen
//     (that's why wxGTK will *not* switch to using gtk_window_fullscreen
//     unless it has better compatibility with older WMs).
//
//
//     This is what wxWidgets does in wxSetFullScreenStateX11:
//       1) if _NET_WM_STATE_FULLSCREEN is supported, use it
//       2) otherwise try WM-specific hacks (KDE, IceWM)
//       3) use _WIN_LAYER and hope that the WM will recognize it
//     The code was tested with:
//     twm, IceWM, WindowMaker, Metacity, kwin, sawfish, lesstif-mwm
