90b53f416c Use universal helper for writing toplevels to QDebug streams
Toplevel::debug() is one of annoyances that you need to deal with when
implementing a new client type. It can be tempting to just write "this"
to the stream, but it will result in a crash.

In order to make implementing new client types easier, this change
introduces a debug stream insertion operator overload that works for all
kinds of the Toplevel class.

1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the

cf27128877 Update input transformation matrix when buffer geometry changes
Currently, we update the input transformation matrix for the focused
pointer surface only when the frameGeometryChanged() signal is emitted.
However, since the input transformation matrix is computed based on the
current position of the upper left corner of the main surface, it is
wrong to do so because the frame geometry is a logical geometry that
doesn't have any direct relationship with the buffer geometry, i.e. the
rect on the screen occupied by the main surface.

If the input transformation matrix gets out of sync, user may notice
that pointer events are "shifted."

This change introduces a new signal that's emitted when the input
transformation matrix has been changed. Input related components in kwin
can connect to it to keep a copy of the input transformation matrix in
SeatInterface in sync. Under the hood, the new signal is just an alias
for the bufferGeometryChanged() signal.

9c55c01767 Introduce a signal that notifies about new buffer geometry
The new signal can be useful if one wants to watch a toplevel for buffer
geometry updates. This can be especially useful for input related code
because the position of the upper left corner of the main surface is used
to compute the input transformation matrix.

cc3eb54b32 Introduce the client geometry in Toplevel
In most cases, we don't need to react to client geometry changes, but in
code that deals with server-side window decorations, we need to react to
client geometry changes. The problem is that frame and client geometry
updates are not correlated even though there is a connection between the
frame geometry and the client geometry.

This change introduces the client geometry in the Toplevel class in order
to allow monitoring client geometry updates from DecoratedClientImpl.

15af09c70a Introduce Toplevel::frameGeometryChanged signal
Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...

The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.

This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.

We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

This reverts commit 9151bb7b9e.
This reverts commit ac4dce1c20.
This reverts commit 754b72d155.

In order to make the fix work, we need to redirect the client window
instead of the frame window. However, we cannot to do that because
Xwayland expects the toplevel window(in our case, the frame window)
to be redirected.

Another solution to the texture bleeding issue must be found.

754b72d155 [x11] Name client pixmap instead of frame pixmap
Summary:
Since KDE 4.2 - 4.3 times, KWin doesn't paint window decorations on real
X11 windows, except when compositing is turned off. This leaves us with
a problem. The actual client contents is inside a larger texture with no
useful pixel data around it. This and decoration texture bleeding are
the main factors that contribute to 1px gap between the server-side
decoration and client contents with effects such as wobbly windows, and
zoom.

Another problem with naming frame pixmap instead of client pixmap is
that it doesn't quite go along with wayland. It only makes more difficult
to abstract window quad generation in the scene.

Since we don't actually need the frame window when compositing is on,
there is nothing that holds us from redirecting client windows instead
of frame windows. This will help us to fix the texture bleeding issue
and also help us with the ongoing redesign of the scene.

Test Plan: X11 clients are still composited.

9d4a32596c Drop some custom list typedefs
Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example

    QList<QWeakPointer<TabBoxClient>> TabBoxClientList

in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?

Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.

So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Test Plan: Compiles.

fb2d4c113f Adjust scene for client-side decorated clients
Summary:
Currently our Scene is quite naive about geometry. It assumes that the
window frame wraps the attached buffer/client. While this is true for X11
clients, such geometry model is not suitable for client-side decorated
clients, in our case for xdg-shell clients that set window geometry
other than the bounding rectangle of the main surface.

In general, the proposed solution doesn't make any concrete assumptions
about the order between frame and buffer geometry, however we may still
need to reconsider the design of Scene once it starts to generate quads
for sub-surfaces.

9f7a856d23 [wayland] Implement window geometry more properly
Summary:
So far the window geometry from xdg-shell wasn't implemented as it should
be. A toplevel must have two geometries assigned to it - frame and buffer.
The frame geometry describes bounds of the client excluding server-side
and client-side drop-shadows. The buffer geometry specifies rectangle on
the screen occupied by the main surface.

State and geometry handling in XdgShellClient is still a bit broken. This
change doesn't intend to fix that, it must be done in another patch asap.

Test Plan: New tests pass.

7d4471eba6 Rename geometry property to frameGeometry
Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.

This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

bebe81209c Port QPA away from Wayland
Summary:
So far wayland was used by internal clients to submit raster buffers
and position themselves on the screen. While we didn't have issues with
submitting raster buffers, there were some problems with positioning
task switchers. Mostly, because we had effectively two paths that may
alter geometry.

A better approach to deal with internal clients is to let our QPA use
kwin core api directly. This way we can eliminate unnecessary roundtrips
as well make geometry handling much easier and comprehensible.

The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
style use platform-specific APIs to set and unset shadows. We need to
add shadows API to KWindowSystem. Even though some internal clients lack
drop-shadows at the moment, I don't consider it to be a blocker. We can
add shadows back later on.

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

8af2fa73dc Run clang-tidy with modernize-use-override check
Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.

The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.

Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.

A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!

The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.

The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

dbus interface is extended by a value whether the window is on the
localhost. This is exposed through a virtual method on toplevel which is
overridden in ShellClient and there always returning true.

90a26e2e8d Try to invalidate quad cache when shadow is changed
Summary:
213239a0ea tried to address the case when
a wayland client gets shadow after it was mapped, but because of poor
testing from my side, another bug was introduced. If a decoration tooltip
or the user actions popup is shown, then in some cases it can be blank.

Usually, SurfaceInterface::shadowChanged proceeds SurfaceInterface::sizeChanged,
so when the shadow is installed, window quads cache is rebuilt. But
because shell client already knows the geometry of the internal client,
goemetryShapeChanged is not emitted, thus the cache is not updated.

It would be better just to invalidate the cache when the shadow is
installed, uninstalled, or updated. This reduces the number of
unnecessary invocations of Scene::Window::buildQuads and also moves
handling of the window quads cache away from the Shadow class.

BUG: 399490

3ad9ac7229 Introduce the concept of an internal window system independent id
Summary:
For supporting Wayland windows in the kwin_rules_dialog we need a way to
pass a window id for Wayland windows to the dialog. This id needs to be
sent to the dbus interface to query window information just like the
interactive query. For Wayland windows we don't really have a window id
and it would require to also pass the windowing system to
kwin_rules_dialog and back through the dbus interface.

To not complicate things this change introduces a windowing system
independent id based on UUID. This could in future also be used
internally for areas where it's window id based and used in both
windowing systems.

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.

fc887ab907 Render GL Window decorations at the correct scale
Summary:
Under wayland we support high DPI putting by putting a separation
between the logical co-ordinate system and the resolution of rendered
assets.

When a window is on a high DPI screen, we should render at the higher
resolution.

Like the window scaling this handles any combination of a 2x scaled
decoration being rendered on a 1x screen or vice versa.

---
This patch is a bit different from the other scaling stuff. We have to
generate the quads *before* we have an updated texture with the new
scale. This means the scale isn't attached to the buffer like elsewhere.

That's why I added a property in TopLevel so there's still one canonical
source and things can't get out of sync.

BUG: 384765

Test Plan:
Crystal clear breeze and oxygen decos on my @2x display
Drag windows to attached @1x display, things still look OK when across 2
screens
Changing the scale of a screen updated the decos instantly

0ed609590b Add a dedicated X11EventFilter for forwarding property events to the effect system
Summary:
So far both Workspace and Toplevel emitted signals for every property
notify event on the root window and the respective Toplevel windows. The
signals were only used in EffectsHandlerImpl to forward to the effect
system in case the property which changed is registered by an effect.

This change introduces a dedicated event filter for this which is only
created in EffectsHandlerImpl in case an X11 connection is available. It
supports a restart of the X11 system.

The signals used so far are removed from Workspace and Toplevel.
