 183 // NB: Setting fullscreen mode under X11 is a complicated matter. There was
 184 //     no standard way of doing it until recently. ICCCM doesn't know the
 185 //     concept of fullscreen windows and the only way to make a window
 186 //     fullscreen is to remove decorations, resize it to cover entire screen
 187 //     and set WIN_LAYER_ABOVE_DOCK.
 188 //
 189 //     This doesn't always work, though. Specifically, at least kwin from
 190 //     KDE 3 ignores the hint. The only way to make kwin accept our request
 191 //     is to emulate the way Qt does it. That is, unmap the window, set
 192 //     _NET_WM_WINDOW_TYPE to _KDE_NET_WM_WINDOW_TYPE_OVERRIDE (KDE extension),
 193 //     add _NET_WM_STATE_STAYS_ON_TOP (ditto) to _NET_WM_STATE and map
 194 //     the window again.
 195 //
 196 //     Version 1.2 of Window Manager Specification (aka wm-spec aka
 197 //     Extended Window Manager Hints) introduced _NET_WM_STATE_FULLSCREEN
 198 //     window state which provides cleanest and simplest possible way of
 199 //     making a window fullscreen. WM-spec is a de-facto standard adopted
 200 //     by GNOME and KDE folks, but _NET_WM_STATE_FULLSCREEN isn't yet widely
 201 //     supported. As of January 2003, only GNOME 2's default WM Metacity
 202 //     implements, KDE will support it from version 3.2. At toolkits level,
 203 //     GTK+ >= 2.1.2 uses it as the only method of making windows fullscreen
 204 //     (that's why wxGTK will *not* switch to using gtk_window_fullscreen
 205 //     unless it has better compatibility with older WMs).
 206 //
 207 //
 208 //     This is what wxWidgets does in wxSetFullScreenStateX11:
 209 //       1) if _NET_WM_STATE_FULLSCREEN is supported, use it
 210 //       2) otherwise try WM-specific hacks (KDE, IceWM)
 211 //       3) use _WIN_LAYER and hope that the WM will recognize it
 212 //     The code was tested with:
 213 //     twm, IceWM, WindowMaker, Metacity, kwin, sawfish, lesstif-mwm
