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.
This change adds a default handle for screen edge based activation in
order to reduce the amount of boilerplate in client sub-classes that do
not support features such as auto-hiding, e.g. popups.
Currently, we have two functions that update the color scheme for a
client - updateColorScheme(QString) and updateColorScheme(). Even though
they both share the same name, they do different things. The first one
sets the specified color scheme, while the other determines the color
scheme preferred by the client and assigns it.
This change refactors the color scheme initialization code so we no
longer need those two methods. The setColorScheme() method sets the
specified color scheme, and the preferredColorScheme() method returns
the color scheme preferred by the client. Sub-classes of AbstractClient
can override the preferredColorScheme() method in order to add support
for platform-specific color scheme protocols.
The end result: color scheme related code is a bit more comprehensible.
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
toplevel source directory.
In rare cases, Workspace::restoreFocus() may fail, for example when the
most recently activated client is about to be destroyed or unmapped.
If it happens that we cannot restore the focus, then mark the window in
FocusIn event as active.

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.
Summary:
Prefer virtual methods that take QRect and QSize rather than multi-int versions.
Makes for clearer API and reduces the amount of code that was taking all of the
components and turn it into a class.

Summary:
We have duplicated code in InternalClient and XdgShellClient to create
decorations. In order to get rid of the code duplication, this change
introduces a method that AbstractClient subclasses can call to create
a window decoration.
Test Plan: Tests pass.

The new method provides a generic way for destructing clients. Notice
that we can't just delete clients because we may need to discard
temporary window rules, which is usually done in destroyClient().

Summary:
Not all Client classes have support for the maximized mode. Therefore,
it can be made opt-in to reduce the amount of plumbed methods.
Unfortunately, there a few places, which don't have any connection with
the maximized mode, where AbstractClient::geometryRestore() is used, so
it cannot be made 100% optional at the moment.

Summary:
In long term, we want to split XdgShellClient into several classes. One
class for xdg-toplevel clients, and the other one for xdg-popup clients.
xdg-popup clients are much simpler than xdg-toplevel clients, they can't
be maximized or shown in full screen mode, they can't be interactively
moved on the screen, and so on. In the end, we will have to plumb many
pure virtual methods, which looks a bit ugly.
This change makes support for the minimized state in AbstractClient
optional so we don't have to add those no-op methods and keep code more
or less "clean."
Test Plan: Compiles.

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.

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.

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.

Summary:
There are rules that have to be applied only once, e.g. every Remember
and Apply Initially rule, as well rules that need to configure the client,
e.g. size, etc. In the best scenario the compositor would evaluate such
rules when the client is about to be mapped.
This change limits window rules only to xdg-shell clients because right
now only this protocol lets compositors to intervene in the client
initialization process. Also, it makes things a bit easier for us on the
compositor side.
xdg-shell protocol satisfies most of ours requirements to implement window
rules, but not all of them. If the client is about to be mapped for the
second time and its size is forced by a rule, then compositor may need
to configure it. Currently, xdg-shell protocol doesn't have any mechanism
that a client could use to notify the compositor about its intent to map.

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.
