// 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
