/** Functions for handling input devices.
 *
 * 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. Under X, the support for multiple
 * input devices is done through the XInput 2 extension,
 * which also supports additional features such as sub-pixel positioning
 * information and additional device-dependent information.
 *
 * 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(),
 * although there would rarely be a reason to do that. For a widget or
 * window to be dealt as multipointer aware,
 * Gdk::Window::set_support_multidevice() or
 * Gtk::Widget::set_support_multidevice() must have been called on it.
 *
 * 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.
 *
 * By default, GDK will automatically listen for events coming from all
 * master devices, setting the Gdk::Device 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.
 *
 * Although gdk_window_set_support_multidevice() must be called on
 * \#GdkWindows in order to support additional features of multiple pointer
 * interaction, such as multiple per-device enter/leave events, the default
 * setting will emit just one enter/leave event pair for all devices on the
 * window. See Gdk::Window::set_support_multidevice() documentation for more
 * information.
 *
 * In order to listen for events coming from other than a virtual device,
 * Gdk::Window::set_device_events() must be called. Generally, this method
 * 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::Devie::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 Gdk::Device::property_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().
 *
 * 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
 * Gdk::DeviceManager. On X11, multidevice support is implemented through
 * XInput 2. Unless gdk_disable_multidevice() is called, the XInput 2.x
 * Gdk::DeviceManager implementation will be used as the input source. Otherwise
 * either the core or XInput 1.x implementations will be used.
 *
 * In gtkmm 3.20, a new Gdk::Seat object has been introduced that
 * supersedes Gdk::DeviceManager and should be preferred in newly
 * written code.
