++ textures in graphics memory between compositor and multiple clients.
++
++ ****************************************************************************
++ * Compositor *
++ ****************************************************************************
++
++ - 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.
++
++ ****************************************************************************
++ * QPA plugin *
++ ****************************************************************************
++
++ - Pixel delta is now set for mouse scrolling events if originating from an
++ appropriate device such as a touch pad (requires compositor support for
++ wl_seat version 5 or later).
++ - 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.

++ qtwaylandscanner generated types now have a fromObject function which
++ will return nullptr if the object isn't wrapped by the type.
