Currently, the wayland backend does not monitor when its buffers are
released by the host compositor, which can potentially result in
glitches.
This change refactors the wayland backend so the swapchain buffers are
released upon receiving wl_buffer.release event.
wl_buffer.release event handling lives in the WaylandBackend. This
allows us to share some code, it might also be useful for implementing
direct scanout as any GraphicsBuffer providing dmabuf or shm attributes
can be wrapped in a wl_buffer.
Use a ToolButton rather than a Button for the close icon to reduce
unnecessary visual weight, and move it outwards so that its frame
touches the inner edge of the selection rectangle. Looks a bit nicer and
less attention-getting.
This makes it follow a common KDE convention of using bold text to
indicate which item in a set is active or current. Doing it here too
helps direct visual attention to the selected item, improving speed of
interaction.
Per https://invent.kde.org/plasma/plasma-desktop/-/issues/53, we're
making an overhauled version of the Thumbnail Grid Task Switcher the
default one in Plasma 6.
Currently the default Task Switcher is specified as the "Breeze" Task
Switcher which isn't ideal since it doesn't live in this repo, and it's
possible to use KWin without Plasma, where it does live.
So as a part of making Thumbnail Grid the new default Task Switcher,
let's also move it here so that KWin's default Task Switcher is always
available.
This commit grabs the Thumbnail Grid Task Switcher verbatim from where
it currently lives in the kdeplasma-addons-repo as of commit
54d16f44a56530854444b844536933a3107ef8a6.

Currently the tablet cursor doesn't use SurfaceCursorSource because it
doesn't handle changing the surface size after the set_cursor request.
This change adds missing surface commit handling in the
SurfaceCursorSource so the tablet cursor can use it. As a side effect,
the pointer interface doesn't need to track surface commits anymore.
It was initialized to different values in the header and
in the constructor. Let's remove one of them to avoid
the confusion

Previously, the switcher item got hidden immediately after
selecting a window, so it wasn't possible to show an exit
transition.
Emit instead an `aboutToHide` signal and let the switchers
that opt-in to handle when to hide the tabbox by just setting
its `visible` property to `false`. In the default case we handle
that signal by immediately hiding the tabbox as usual.
For symmetry, add also a new `aboutToShow` signal which
simplifies setting an enter transition.
Sticky keys allow to trigger key combinations one key at a time.
This is an accessibility feature used by people that cannot press
multiple keys simultaneously.
On X11 this is handled by the X server, configured via kaccess.
On Wayland we get to handle this ourselves.
wl_keyboard events already carry the modifier's latched/locked state, so
all we need to do is to
make sure the right state is set
Xkb gains a new method to set the state. The business logic is
implemented in a new plugin
that filters for keys and sets the Xkb state accordingly.

This change introduces InputDevice::pointerFrame(). The main motivation
behind it is to allow batching multiple pointer events within a single
event frame.

It appears like gbm_VERSION can be a list, which if() does not like. So
pass the variable to the if() rather than its value. While on this, also
change GREATER_EQUAL to VERSION_GREATER_EQUAL so cmake compares
individual version components.
Qt requires xcb-icccm 0.3.9. On the other hand, 0.3.9 contains all the
types and functions used by kwin, so remove the corresponding
XCB_ICCM_FOUND checks to simplify the code.
At the moment, clicking desktop thumbnails in the desktop bar results in
switching to that virtual desktop, which is not ideal because the
overview effect allows sending windows to another virtual desktop by drag
and dropping them to its thumbnail but you can't jump to that
desktop unless you leave the overview effect.

The ClientBuffer type is empty now, most of the things have been
upstreamed to the GraphicsBuffer type. So let's drop it to simplify the
type hierarchy.
ClientBufferIntegration was introduced to work around the fact that some
client buffers are not created by us.
In addition to that, DisplayPrivate::registerClientBuffer() was
introduced to register client buffers created by us.
This change get rids of the ClientBufferIntegration type and further
simplifies the ClientBuffer type to make wayland-specific client buffer
code less messier.
