/**
* gdk_x11_screen_supports_net_wm_hint:
* @screen: (type GdkX11Screen): the relevant #GdkScreen.
* @property: a property atom.
*
* This function is specific to the X11 backend of GDK, and indicates
* whether the window manager supports a certain hint from the
* [Extended Window Manager Hints](http://www.freedesktop.org/Standards/wm-spec) specification.
*
* When using this function, keep in mind that the window manager
* can change over time; so you shouldn’t use this function in
* a way that impacts persistent application state. A common bug
* is that your application can start up before the window manager
* does when the user logs in, and before the window manager starts
* gdk_x11_screen_supports_net_wm_hint() will return %FALSE for every property.
* You can monitor the window_manager_changed signal on #GdkScreen to detect
* a window manager change.
*
* Returns: %TRUE if the window manager supports @property
*
* Since: 2.2
