d2fb4147fc Move multi-purpose code in its own directory
Things such as Output, InputDevice and so on are made to be
multi-purpose. In order to make this separation more clear, this change
moves that code in the core directory. Some things still link to the
abstraction level above (kwin), they can be tackled in future refactors.
Ideally code in core/ should depend either on other code in core/ or
system libs.

c3d5c3db1d x11: Add a helper to get the default screen
Since the screen number is well-known, we can look up the default
screen on demand. Note that xcb_get_setup() is pretty cheap as it
simply returns a const pointer to pre-allocated data.

4bfb0acc17 Make Workspace track managed outputs
This change adjusts the window management abstractions in kwin for the
drm backend providing more than just "desktop" outputs.

Besides that, it has other potential benefits - for example, the
Workspace could start managing allocation of the placeholder output by
itself, thus leading to some simplifications in the drm backend. Another
is that it lets us move wayland code from the drm backend.

7292af3d04 Use floating geometry throughout
With fractional scaling integer based logical geometry may not match
device pixels. Once we have a floating point base we can fix that. This
also is
important for our X11 scale override, with a scale of 2 we could
get logical sizes with halves.

We already have all input being floating point, this doubles down on it
for all remaining geometry.

- Outputs remain integer to ensure that any screen on the right remains
aligned.
 - Placement also remains integer based for now.
- Repainting is untouched as we always expand outwards
 			   (QRectF::toAdjustedRect().
 - Decoration is untouched for now
 - Rules are integer in the config, but floating in the adjusting/API
This should also be fine.

At some point we'll add a method to snap to the device pixel
grid. Effectively `round(value * dpr)  / dpr` though right now things
mostly work.

This also gets rid of a lot of hacks for QRect right and bottom which
are very
confusing.

Parts to watch out in the port are:
 QRectF::contains now includes edges
QRectF::right and bottom are now sane so previous hacks have to be
removed
 QRectF(QPoint, QPoint) behaves differently for the same reason
 QRectF::center too

In test results some adjusted values which are the result of
QRect.center because using QRectF's center should behave the same to the
user.

6d0cca5c7f Move all dirty region scene repaint scheduling to Scene
The Compositor contains nothing that can potentially get dirty and need

As is, the advantages of this move aren't really noticeable, but it
makes sense with multiple scenes.

Backend parts are far from ideal, they can be improved later on as we

141947d2e8 effects: Link builtin effects with executables
The main motivation behind this change is to prepare kwin for importing
kwayland-server code in libkwin.

As is, builtin effects are linked with libkwin. Some builtin effects
have wayland specific code. If we move wayland stuff in libkwin, there's
going to be a circular dependency between kwin4_effect_builtins and
libkwin targets.

This change intends to break that dependency by linking builtin effects
to kwin executable.

The main issue with that is that EffectLoader would need to discover the
effects indirectly. QStaticPlugin is used for that purpose.

Besides breaking the cyclic dependency, it makes builtin effects use the
same plugin infrastructure in libkwineffects that external effects use.

Metadata in src/effects/effect_builtins.cpp was converted in a list of
python dictionaries, which was fed to a python script that generated
main.cpp and metadata.json files.

964c487d4f wayland: Switch to ClientBuffer
The main motivation behind the split is to simplify client buffer code
and allow adding new features easier, for example referencing the shm
pool when a shm buffer is destroyed, or monitoring for readable linux
dmabuf file descriptors, etc.

Also, a referenced ClientBuffer cannot be destroyed, unlike the old
BufferInterface.

46b81be246 autotests: Make SceneQPainterTest more robust to BufferInterface changes
At the moment, the test depends on the implicit client connection flush
in BufferInterface::unref(). It will be highly desirable if that connection
flush is gone as it allows us batching wayland events better. It also
allows us remove a system call from a hot path.

1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional

lot of boilerplate text.

6abd23ed02 Make it possible to have a separate cursor for the tablet
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.

be759b7d33 Use AbstractClient instead of XdgShellClient wherever possible
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.

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.

ffcbe24e2b Rename Client to X11Client
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.

d92d6e77ae [autotests] Don't test wl-shell clients
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.

cbbe94d769 Restrict available supported compositors based on first initialized one
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.

e3250460cc Do not unset cursor image when cursor enters a surface
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
