Summary:
When resizing a window particularly from the left side, we need to
co-ordinate moving the window with when we get the resized buffer.
The code in AbstractClient::handleMoveResize checks
isWaitingForResizSync to make sure we never send more than one resize
request at a time to keep that in sync.
This makes sense on X and wl_shell_surface, but not on XDGShell where we
can track which resize events have been handled by the client.
ShellClient already keeps a stack of our pending configure requests and
handles everything appropriately, we don't need to block.
This results in a smoother dragging experience and avoids a potential
deadlock currently seen when a client may not reply to a no-op configure
request.

Summary:
When user asks KWin to show desktop, the compositor just raises every
desktop window, it doesn't attempt to minimize normal clients, etc.
Because desktop windows contain stuff like background and icons, the
compositor has to raise all clients that are somehow correlated with
desktop (e.g. panels, etc). Otherwise it would pretty weird to show only
desktop background.
Currently, not all plasmashell's clients are raised when the compositor
shows desktop because belongsToDesktop is not implemented for ShellClient.

Summary:
Everything on the wl_surface is double buffered.
When we create an XdgShell toplevel or popup we shouldn't treat it as
attached until it's committed to the surface.
A client should commit the surface after it's sent it's initial state of
the Xdg topLevel; minimumSize, title, app_id, etc.
By blocking sending configure events we will have flushed the correct
initial state before sending a single atomic correct event to the
client. It also adds a hook to re-evaluate rules now that all properties
are set.
Arguably this applies to WlShellSurface too, but I've left it unchanged
as it's deprecated and hard to verify real client behaviour.

Summary: When creating a surface and setting it as fullscreen before
attaching its buffer KWin does not know the original dimensions of the
surface and tries to use an invalid value when unsetting the fullscreen
flag. This patch fixes this by sending a configure with the size of 0,0
- which according to xdg-shell spec means that the client is requested
to set its size by itself.
Test Plan:
1. Create a fullscreen Wayland window.
2. Toggle fullscreen off.
3. KWin should send a configure event with size 0,0 instead of 1,1.

placeIn did not handle the case for a popup not having had the size
already set and only being available via

at the correct time, before the window is mapped.
There was also a logic bug when sliding popups. We called the
confusingly named setX thinking it would be move the popup keeping the
width the same. In practice it moves the left edge keeping the right
position the same. This wasn't an issue as the size was
discarded.
Handling the resize constraint is not yet done, but it should now be

Summary:
Most of the functionality which is special to internal clients is moved
from ShellClient to InternalClient. As KWin's qpa is still bound to the
Wayland protocol InternalClient inherits from ShellClient. Due to that
some aspects in ShellClient are "weird". ShellClient still detects
whether it's an internal client and uses the variable m_internal to
capture the state. This is required as we cannot use the isInternal
method. Most of m_internal usage is in init which is called from
constructor of ShellClient. Thus it's not possible to call into virtual
methods of InternalClient.
Also some of the code is duplicated and some methods are temporarily
marked as virtual.
The next step will be to remove ShmBuffer for internal windows which
should decouple the two implementations further with the long term goal
of having InternalClient inherit AbstractClient directly.
Test Plan:
Run nested KWin, triggered outline (OpenGL case) and debug console (shm case).
InternalWindow unit test still passes.

Summary:
KWindowSystem provides a plugin interface to have platform specific
implementations. So far KWin relied on the implementation in
KWayland-integration repository.
This is something I find unsuited, for the following reasons:
* any test in KWin for functionality set through the plugin would fail
* it's not clear what's going on where
* in worst case some code could deadlock
* KWin shouldn't use KWindowSystem and only a small subset is allowed
to be used
The last point needs some further explanation. KWin internally does not
and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is
exposing information which KWin sets. It's more than weird if KWin asks
KWindowSystem for the state of a window it set itself. On X11 it's just
slow, on Wayland it can result in roundtrips to KWin itself which is
dangerous.
But due to using Plasma components we have a few areas where we use
KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in
direction, blur and background contrast. This we want to support and
need to support. Other API elements we do not want, like for examples
the available windows. KWin internal windows either have direct access
to KWin or a scripting interface exposed providing (limited) access -
there is just no need to have this in KWindowSystem.
To make it more clear what KWin supports as API of KWindowSystem for
internal windows this change implements a stripped down version of the
kwayland-integration plugin. The main difference is that it does not use
KWayland at all, but a QWindow internal side channel.
To support this EffectWindow provides an accessor for internalWindow and
the three already mentioned effects are adjusted to read from the
internal QWindow and it's dynamic properties.
This change is a first step for a further refactoring. I plan to split
the internal window out of ShellClient into a dedicated class. I think
there are nowadays too many special cases. If it moves out there is the
question whether we really want to use Wayland for the internal windows
or whether this is just historic ballast (after all we used to use
qwayland for that in the beginning).
As the change could introduce regressions I'm targetting 5.16.
Test Plan:
new test case for window type, manual testing using Alt+Tab
for the effects integration. Sliding popups, blur and contrast worked fine.

Summary:
Previously when updating the state we would send a configure event with
the size 0,0. This means the client chooses the size. For regular window
this works as most toolkits treat this to mean the size that we

For maximised windows it's a problem, the spec clearly states that when
maximised clients must follow the size given. Telling the client to be
0,0 doesn't make sense.
By always sending our last requested size we remove any ambiguity.

The Scale effect and the Glide effect have to animate only ordinary
windows(i.e. the ones that are considered to be apps).
On X11, in order to distinguish ordinary windows from combo box popups,
popup menus, and other popups, those effects check whether given window
is managed.
On Wayland, there is no concept of managed/unmanaged windows.
XDG Shell protocol defines 2 surface roles:
* xdg_toplevel;
* and, xdg_popup.
The former can be used to implement typical windows, the ones that can
be minimized, maximized, etc.
The latter can be used to implement tooltips, popup menus, etc. Thus,
that's a good criteria to filter popup windows.

Currently we process the new position the next time the buffer updates,

The client could be providing a new buffer just because the contents
have changed.
XDGShell has an acked serial designed to keep everything precisely in
sync. A surface represents the last configure that was acked.
This patch tracks the pending position for each configure and applies it
accordingly.
WL_shell does not have this mechanism, so behaviour is kept the same as
before.

happens in ShellClient, which is too late to catch that the window
requested client side decoration. Thus KWin created a decoration about
things such as a menu.
This change moves the acknowledge of the mode to WaylandServer. As we
anyway always acknowledge the requested mode we can also do it there and
don't require ShellClient to be present. Thus when the ShellClient is
