/**
 * @page page_tablet_unstable_v2 The tablet_unstable_v2 protocol
 * Wayland protocol for graphics tablets
 *
 * @section page_desc_tablet_unstable_v2 Description
 *
 * This description provides a high-level overview of the interplay between
 * the interfaces defined this protocol. For details, see the protocol
 * specification.
 *
 * More than one tablet may exist, and device-specifics matter. Tablets are
 * not represented by a single virtual device like wl_pointer. A client
 * binds to the tablet manager object which is just a proxy object. From
 * that, the client requests wp_tablet_manager.get_tablet_seat(wl_seat)
 * and that returns the actual interface that has all the tablets. With
 * this indirection, we can avoid merging wp_tablet into the actual Wayland
 * protocol, a long-term benefit.
 *
 * The wp_tablet_seat sends a "tablet added" event for each tablet
 * connected. That event is followed by descriptive events about the
 * hardware; currently that includes events for name, vid/pid and
 * a wp_tablet.path event that describes a local path. This path can be
 * used to uniquely identify a tablet or get more information through
 * libwacom. Emulated or nested tablets can skip any of those, e.g. a
 * virtual tablet may not have a vid/pid. The sequence of descriptive
 * events is terminated by a wp_tablet.done event to signal that a client
 * may now finalize any initialization for that tablet.
 *
 * Events from tablets require a tool in proximity. Tools are also managed
 * by the tablet seat; a "tool added" event is sent whenever a tool is new
 * to the compositor. That event is followed by a number of descriptive
 * events about the hardware; currently that includes capabilities,
 * hardware id and serial number, and tool type. Similar to the tablet
 * interface, a wp_tablet_tool.done event is sent to terminate that initial
 * sequence.
 *
 * Any event from a tool happens on the wp_tablet_tool interface. When the
 * tool gets into proximity of the tablet, a proximity_in event is sent on
 * the wp_tablet_tool interface, listing the tablet and the surface. That
 * event is followed by a motion event with the coordinates. After that,
 * it's the usual motion, axis, button, etc. events. The protocol's
 * serialisation means events are grouped by wp_tablet_tool.frame events.
 *
 * Two special events (that don't exist in X) are down and up. They signal
 * "tip touching the surface". For tablets without real proximity
 * detection, the sequence is: proximity_in, motion, down, frame.
 *
 * When the tool leaves proximity, a proximity_out event is sent. If any
 * button is still down, a button release event is sent before this
 * proximity event. These button events are sent in the same frame as the
 * proximity event to signal to the client that the buttons were held when
 * the tool left proximity.
 *
 * If the tool moves out of the surface but stays in proximity (i.e.
 * between windows), compositor-specific grab policies apply. This usually
 * means that the proximity-out is delayed until all buttons are released.
 *
 * Moving a tool physically from one tablet to the other has no real effect
 * on the protocol, since we already have the tool object from the "tool
 * added" event. All the information is already there and the proximity
 * events on both tablets are all a client needs to reconstruct what
 * happened.
 *
 * Some extra axes are normalized, i.e. the client knows the range as
 * specified in the protocol (e.g. [0, 65535]), the granularity however is
 * unknown. The current normalized axes are pressure, distance, and slider.
 *
 * Other extra axes are in physical units as specified in the protocol.
 * The current extra axes with physical units are tilt, rotation and
 * wheel rotation.
 *
 * Since tablets work independently of the pointer controlled by the mouse,
 * the focus handling is independent too and controlled by proximity.
 * The wp_tablet_tool.set_cursor request sets a tool-specific cursor.
 * This cursor surface may be the same as the mouse cursor, and it may be
 * the same across tools but it is possible to be more fine-grained. For
 * example, a client may set different cursors for the pen and eraser.
 *
 * Tools are generally independent of tablets and it is
 * compositor-specific policy when a tool can be removed. Common approaches
 * will likely include some form of removing a tool when all tablets the
 * tool was used on are removed.
 *
 * Warning! The protocol described in this file is experimental and
 * backward incompatible changes may be made. Backward compatible changes
 * may be added together with the corresponding interface version bump.
 * Backward incompatible changes are done by bumping the version number in
 * the protocol and interface names and resetting the interface version.
 * Once the protocol is to be declared stable, the 'z' prefix and the
 * version number in the protocol and interface names are removed and the
 * interface version number is reset.
