In KF we already looking for 5.15.2
and looking something lower than that
is a bit meaningless

See https://gitlab.freedesktop.org/wayland/wayland/-/merge_requests/123

Basically this is a well known issue in wayland for globals. If bind
comes after destroyed, it will raise a invalid global error. The common
practice is to delay the destroy of global. Similar technique is also
applied to wl_output.

CCBUG: 452435

The API of SurfaceInterface was changed so it always maintains an opaque
region.

At the surface commit, if the attached buffer is opaque, the whole
surface will be marked opaque. Otherwise, the specified opaque region
will be intersected with the surface rect.

That's a leftover from before resurrecting the qtwaylandscanner fork here
for Qt6.

This allows to get the resource name for XWayland windows, which is useful in the task manager

If no mode has the current flag set, the first mode object will be
announced twice.

There's also no benefit from sending the current mode as last. If the
current mode changes, the compositor will send the current_mode event,
not the mode event.

CCBUG: 452318

Whilst a subsurface must have a parent at the time of creation, the
lifespan is not guaranteed afterwards.

It's a weird thing for a client to do, but we need to not crash
afterwards.

If the parent surface is destroyed we should consider the surface
unmapped.

BUG: 452044

In the current form any client committing multiple times without
attaching a buffer would unset the cached state and trigger an error.

It's legal (though weird) to commit multiple times before attaching a
buffer.

We should only reset the state if we commit an empty buffer after having
committed an existing buffer. This brings us in line with XdgShell.

This allows us to simplify rendering code in the compositor.

Needed to compile against Qt6.

Qt6 QList::operator!= fails to compile otherwise.

This unfortunately clashes with a typedef in a Qt6 header.

QVector is much more suitable for modifiers in KWin than QSet, because you
can access the underlying array

If this is not done then KScreen will sometimes unintentionally reset them
to the default.

BUG: 442520
FIXED-IN: 5.24.4

Currently, if the pointer surface has to change between two surfaces,
the compositor must do the following

    seat->setFocusedPointerSurface(nullptr);
    seat->notifyPointerMotion(newPos);
    seat->setFocusedPointerSurface(focus);

The pointer motion is needed so the enter event has correct position,
setFocusedPointerSurface(nullptr) is needed to avoid sending a bad
motion event before the leave event.

This change makes the pointer focus api less error prone by splitting
setFocusedPointerSurface() in two functions - notifyPointerEnter() and
notifyPointerLeave().

notifyPointerEnter() takes new focus surface as well as the position
where the pointer has entered the surface so the focus update can be
atomic and without any corner cases.

notifyPointerLeave() is used to clear pointer focus.

This is needed to cancel drags by pressing Escape which is
resposibility of the compositor

Consider the cases where we get a touch move or touch up but we never
received a touch down before.

In the case of move, we'll simulate a touchDown right there and move on
with reality.
In the case of touch up, we'll just ignore the event as simulating could
just be more confusing.

BUG: 450338

xdg_toplevel.configure_bounds() allows to indicate the client the
maximum surface size bounds.

When dragging from one window to another, we may end up in a data_device
that didn't get "data_device_start_drag". In that case, the internal
touch point serial will be incorrect and we need to update it to the
serial from the seat. The serial stored in the seat is changed to
std::optional so we can properly check if it is set.

The SeatInterface cleans up currentSelection and currentPrimarySelection
when the AbstractDataSource::aboutToBeDestroyed() signal is emitted, but
since the data source and primary data source have parent objects, they
can be potentially destroyed without emitting the aboutToBeDestroyed()
signal and thus leaving dangling pointers in SeatInterface.

DRM_FORMAT_MOD_INVALID is now explicitly included in KWin where needed

...to reflect reality. It already needs kde-primary-output-v1.xml,
which appeared in 1.6.0.
