/**
 * In addition to a single pointer and keyboard for user interface input,
 * GDK contains support for a variety of input devices, including graphics
 * tablets, touchscreens and multiple pointers/keyboards interacting
 * simultaneously with the user interface. Such input devices often have
 * additional features, such as sub-pixel positioning information and
 * additional device-dependent information.
 *
 * In order to query the device hierarchy and be aware of changes in the
 * device hierarchy (such as virtual devices being created or removed, or
 * physical devices being plugged or unplugged), GDK provides
 * GdkDeviceManager.
 *
 * By default, and if the platform supports it, GDK is aware of multiple
 * keyboard/pointer pairs and multitouch devices. This behavior can be
 * changed by calling gdk_disable_multidevice() before gdk_display_open().
 * There should rarely be a need to do that though, since GDK defaults
 * to a compatibility mode in which it will emit just one enter/leave
 * event pair for all devices on a window. To enable per-device
 * enter/leave events and other multi-pointer interaction features,
 * gdk_window_set_support_multidevice() must be called on
 * GdkWindows (or gtk_widget_set_support_multidevice() on widgets).
 * window. See the gdk_window_set_support_multidevice() documentation
 * for more information.
 *
 * On X11, multi-device support is implemented through XInput 2.
 * Unless gdk_disable_multidevice() is called, the XInput 2
 * GdkDeviceManager implementation will be used as the input source.
 * Otherwise either the core or XInput 1 implementations will be used.
 *
 * For simple applications that don't have any special interest in
 * input devices, the so-called client pointer
 * provides a reasonable approximation to a simple setup with a single
 * pointer and keyboard. The device that has been set as the client
 * pointer can be accessed via gdk_device_manager_get_client_pointer().
 *
 * Conceptually, in multidevice mode there are 2 device types. Virtual
 * devices (or master devices) are represented by the pointer cursors
 * and keyboard foci that are seen on the screen. Physical devices (or
 * slave devices) represent the hardware that is controlling the virtual
 * devices, and thus have no visible cursor on the screen.
 *
 * Virtual devices are always paired, so there is a keyboard device for every
 * pointer device. Associations between devices may be inspected through
 * gdk_device_get_associated_device().
 *
 * There may be several virtual devices, and several physical devices could
 * be controlling each of these virtual devices. Physical devices may also
 * be "floating", which means they are not attached to any virtual device.
 *
 * $(DDOC_COMMENT example)
 *
 * By default, GDK will automatically listen for events coming from all
 * master devices, setting the GdkDevice for all events coming from input
 * devices. Events containing device information are GDK_MOTION_NOTIFY,
 * GDK_BUTTON_PRESS, GDK_2BUTTON_PRESS, GDK_3BUTTON_PRESS,
 * GDK_BUTTON_RELEASE, GDK_SCROLL, GDK_KEY_PRESS, GDK_KEY_RELEASE,
 * GDK_ENTER_NOTIFY, GDK_LEAVE_NOTIFY, GDK_FOCUS_CHANGE,
 * GDK_PROXIMITY_IN, GDK_PROXIMITY_OUT, GDK_DRAG_ENTER, GDK_DRAG_LEAVE,
 * GDK_DRAG_MOTION, GDK_DRAG_STATUS, GDK_DROP_START, GDK_DROP_FINISHED
 * and GDK_GRAB_BROKEN. When dealing with an event on a master device,
 * it is possible to get the source (slave) device that the event originated
 * from via gdk_event_get_source_device().
 *
 * In order to listen for events coming from devices
 * other than a virtual device, gdk_window_set_device_events() must be
 * called. Generally, this function can be used to modify the event mask
 * for any given device.
 *
 * Input devices may also provide additional information besides X/Y.
 * For example, graphics tablets may also provide pressure and X/Y tilt
 * information. This information is device-dependent, and may be
 * queried through gdk_device_get_axis(). In multidevice mode, virtual
 * devices will change axes in order to always represent the physical
 * device that is routing events through it. Whenever the physical device
 * changes, the "n-axes" property will be notified, and
 * gdk_device_list_axes() will return the new device axes.
 *
 * Devices may also have associated keys or
 * macro buttons. Such keys can be globally set to map into normal X
 * keyboard events. The mapping is set using gdk_device_set_key().
