/**
* \brief A variable that forces X11 windows to create as a custom type.
*
* This is currently only used for X11 and ignored elsewhere.
*
* During SDL_CreateWindow, SDL uses the _NET_WM_WINDOW_TYPE X11 property
* to report to the window manager the type of window it wants to create.
* This might be set to various things if SDL_WINDOW_TOOLTIP or
* SDL_WINDOW_POPUP_MENU, etc, were specified. For "normal" windows that
* haven't set a specific type, this hint can be used to specify a custom
* type. For example, a dock window might set this to
* "_NET_WM_WINDOW_TYPE_DOCK".
*
* If not set or set to "", this hint is ignored. This hint must be set
* before the SDL_CreateWindow() call that it is intended to affect.
*
* This hint is available since SDL 2.0.22. Before then, virtual devices are
* always ignored.
