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.
The new signal is emitted when the Application has fully been initialized.
It allows us to change the startup sequence, for example create workspace
before starting the Xwayland server, without making any adjustments in our
test suit.
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.

xdg-shell stable has been around for quite a while. A quick analysis
showed that many distros ship GTK and Qt that support both xdg-shell
v6 and stable. Therefore, we can drop support for legacy v6 protocol.

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing 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:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
This change removes all traces of wl-shell in the test suite. That's a
prerequisite for dropping wl-shell support in KWin.
Given that wl-shell and xdg-shell are not interchangeable, some tests
were removed and initialization sequence in some tests was adjusted.
The most notable change is ensuring that each plasmashell window sets
its role and initial position before committing the surface. Setting
those properties before the first surface commit is important because
our window placement code needs to know window type in order to
avoid maximizing panels, popups, etc.

Summary:
This removes the restart function of the Compositor class and renames the
internal reinitialize function.
Instead of the restart function reinitialize can be called. Reading again
the settings in this case is fine, since it is done rarely. This reduces
the code complexity.
Test Plan: Manually on Wayland and X. 100% autotests pass.

Summary:
On Wayland we cannot switch from OpenGL to QPainter compositor as this
would break any running OpenGL application. KWin registers it's
EGLDisplay to Wayland and without OpenGL this doesn't make sense any
more. We are not able to render OpenGL buffers in the QPainter
compositor.
While it's theoretically possible to switch from QPainter to OpenGL it
doesn't make any sense for the same reason. Any running OpenGL
application would be using llvmpipe and could not be switched to proper
OpenGL.
This change stores the selected compositing type in Platform and the
implementations can use it to restrict the supported compositors. On X11
we don't need this, all other Platforms implement the restriction. Thus
it's no longer possible to switch the backends at runtime.
Test Plan:
Adjusted tests run, no runtime test as gui doesn't support
switching to QPainter anyway.

Summary:
From Wayland documentation:
"When a seat's focus enters a surface, the pointer image is undefined and
a client should respond to this event by setting an appropriate pointer
image with the set_cursor request."
KWin's interpretation so far for the undefined pointer image was to
remove the pointer image when entering a surface waiting for the client
to set a cursor image. This can result in a short flicker as there might
be a frame without a cursor image.
This patch changes the behavior by keeping the previous image till the
application set a new one. This brings some advantages:
* if the application is not responding a cursor is still shown
* if the same cursor is used as in the previous window we don't have a
flicker
CCBUG: 393639
Test Plan: I cannot see the flicker, so only tested with the adjusted tests

Summary:
Adds XDGV6 support for the kwin side.
Popup placement support is limited to the stuff v5 had,
a simple offset, rather than the awesome new positioner.
But Qt doesn't make use of it yet either.
Also ideally we should do all the positioning before sending the first
configure, but again Qt doesn't actually do anything with that anyway.
Also integrate pinging clients

Some distributions (e.g. Arch, FreeBSD) call the DMZ-White cursor theme
Vanilla-DMZ. Due to that our tests are failing even if the correct theme
is installed (see also T6623). This change tries to detect whether
DMZ-White is installed by looking into the GenericDataLocation. If not
found we set to Vanilla-DMZ. No guarantee that the check works for all
setups, but it's only tests...
Needed by testing of QPainter scene to access the back buffer. Exposed
as a virtual method in Scene, so that the test does not have to cast to
SceneQPainter.
D7460 in kwayland assumes all WL_SHM_FORMAT_ARGB8888 buffers have
opacity premultipied RGB values.

The WaylandServer creates the XdgShellV5 interface and hooks it up
to create a ShellSurface whenever an xdg surface or xdg popup is created.
ShellClient gains some new ctors for the different variants and is
adjusted to delegate to xdg surface respectively.
With this change KWin mostly supports xdg-shell protocol. Still missing
is support for the "geometry" request which is rather difficult to
implement in KWin.

New test method which verifies that a newly mapped window is rendered
correctly, that cursor image set on it is rendered correctly, also when
pointer moves.
Summary:
The idea behind this autotest is inspired by bug 356328 which produced
incorrect rendering results. Also it's inspired by openQA which performs
image reference comparisons.
This test case tries to go further. It creates reference images which
must match the rendering result exactly. So far the test case verifies
the start condition - kwin started and one frame is rendered with default
cursor in the middle of the screen. And it verifies the moving of the
cursor without any windows shown. Whenever the cursor moves a repaint
should be triggered and the old and new area should be properly
repainted.
To support this the test needs some minor changes in KWin:
* Scene provides a frameRendered signal - needed for waiting on frame
* Scene and SceneQPainter are exported
* SceneQPainter provides access to it's Backend, so that we get to the
backbuffer
* ScriptedEffectLoader is exported for getting a list of all scripted
effects - (we don't want fade to manipulate the rendering)
