+// 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
