+Qt 5.14 introduces many new features and improvements as well as bugfixes
+over the 5.13.x series. For more details, refer to the online documentation
+included in this distribution. The documentation is also available online:
+
+https://doc.qt.io/qt-5/index.html
+
+The Qt version 5.14 series is binary compatible with the 5.13.x series.
+Applications compiled for 5.13 will continue to run with 5.14.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:
+
+https://bugreports.qt.io/

+Each of these identifiers can be entered in the bug tracker to obtain more
+information about a particular change.

+
+ - Added Vulkan-based server buffer integration for
+   NVIDIA EGLStreams.
+ - [QTBUG-73822] Added protocol and Qt Quick image provider for sharing
+   textures in graphics memory between compositor and multiple clients.

+****************************************************************************
+
+ - The compositor module is no longer available under the GPLv2 and LGPLv3
+   licenses, but is still available under GPLv3 and commercial licenses.
+ - Make QWaylandQuickShellIntegration public so that compositors can
+   provide their code to integrate shell surfaces with QtQuick.
+ - Added QWaylandXdgPopup::sendPopupDone, which will dismiss a popup.
+ - Added support for the idle-inhibit unstable v1 Wayland extension.
+ - The compositor module no longer depends on the client module.
+ - Added support for xdg-output unstable v1 Wayland extension.
+ - Fixed a bug where compositors would advertise support for numerous
+   wl_shm pixel formats and then blindly assume everything to be
+   ARGB32_Premultiplied.
+ - Fixed a crash when destroying WaylandSurfaces and WlShellSurfaces which
+   had not yet been initialized.
+ - The compositor API now works without OpenGL support.
+ - Added a floating point version of QWaylandSurface::inputRegionContains.

+
+ - Pixel delta is now set for mouse scrolling events if originating from an

+ - Added support for animated cursors.
+ - Added support for middle mouse pasting through the
+   primary-selection-unstable-v1 protocol.
+ - Expose default input device to clients through the QPA API.
+ - Fixed a 100 ms freeze that would occur if applications did not draw
+   after receiving a deliverUpdateRequest().
+ - Fixed a crash when showing a window with a hidden parent.
+ - Fixed several crashes when mixing Qt with other wayland code.
+   qtwaylandscanner generated types now have a fromObject function which

+  <description summary="Wayland protocol for graphics tablets">
+    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.

+
+      A wp_tablet_tool object's relation to a physical tool depends on the

+      this capability, then the object represents a specific physical tool
+      and can be identified even when used on multiple tablets.
+
+      A tablet tool has a number of static characteristics, e.g. tool type,
+      hardware_serial and capabilities. These capabilities are sent in an
+      event sequence after the wp_tablet_seat.tool_added event before any
+      actual events from this tool. This initial event sequence is
+      terminated by a wp_tablet_tool.done event.
+

+	with this request it is replaced. If surface is NULL, the cursor
+	image is hidden.
+
+	The parameters hotspot_x and hotspot_y define the position of the
+	pointer surface relative to the pointer location. Its top-left corner
+	is always at (x, y) - (hotspot_x, hotspot_y), where (x, y) are the

+
+	The hotspot can also be updated by passing the currently set pointer

+
+	The current and pending input regions of the wl_surface are cleared,
