 192 // NB: Setting fullscreen mode under X11 is a complicated matter. There was
 193 //     no standard way of doing it until recently. ICCCM doesn't know the
 194 //     concept of fullscreen windows and the only way to make a window
 195 //     fullscreen is to remove decorations, resize it to cover entire screen
 196 //     and set WIN_LAYER_ABOVE_DOCK.
 197 //
 198 //     This doesn't always work, though. Specifically, at least kwin from
 199 //     KDE 3 ignores the hint. The only way to make kwin accept our request
 200 //     is to emulate the way Qt does it. That is, unmap the window, set
 201 //     _NET_WM_WINDOW_TYPE to _KDE_NET_WM_WINDOW_TYPE_OVERRIDE (KDE extension),
 202 //     add _NET_WM_STATE_STAYS_ON_TOP (ditto) to _NET_WM_STATE and map
 203 //     the window again.
 204 //
 205 //     Version 1.2 of Window Manager Specification (aka wm-spec aka
 206 //     Extended Window Manager Hints) introduced _NET_WM_STATE_FULLSCREEN
 207 //     window state which provides cleanest and simplest possible way of
 208 //     making a window fullscreen. WM-spec is a de-facto standard adopted
 209 //     by GNOME and KDE folks, but _NET_WM_STATE_FULLSCREEN isn't yet widely
 210 //     supported. As of January 2003, only GNOME 2's default WM Metacity
 211 //     implements, KDE will support it from version 3.2. At toolkits level,
 212 //     GTK+ >= 2.1.2 uses it as the only method of making windows fullscreen
 213 //     (that's why wxGTK will *not* switch to using gtk_window_fullscreen
 214 //     unless it has better compatibility with older WMs).
 215 //
 216 //
 217 //     This is what wxWidgets does in wxSetFullScreenStateX11:
 218 //       1) if _NET_WM_STATE_FULLSCREEN is supported, use it
 219 //       2) otherwise try WM-specific hacks (KDE, IceWM)
 220 //       3) use _WIN_LAYER and hope that the WM will recognize it
 221 //     The code was tested with:
 222 //     twm, IceWM, WindowMaker, Metacity, kwin, sawfish, lesstif-mwm
