8e7a8c5a11 Rename AbstractOutput to Output
AbstractOutput is not so Abstract and it's common to avoid the word
"Abstract" in class names as it doesn't contribute any new information.
It also significantly reduces the line width in some places.

3534b6afee Remove input processing functions in Platform
Input event flow has been refactored so all input events originate from
input devices.

The X11 backend uses InputRedirection so make it forward events to
relevant input device handlers.

8739258f2f Drop Platform::isPerScreenRenderingEnabled()
At this point, it's safe to assume that only X11 has weird rendering
model, which stands in the way of making rendering abstractions nice and
intuitive, so let's check operation mode. If OperationModeX11 is
dropped, this will also simplify finding X11-specific code in kwin.

a3b5266175 Drop Platform::renderLoop()
Having a render loop in the Platform has always been awkward. Another
way to interpret the platform not supporting per screen rendering would
be that all outputs share the same render loop.

On X11, Scene::painted_screen is going to correspond to the primary
screen, we should not rely on this assumption though!

acea685b04 autotests: Replace output management test with a more useful test
The output management test checks the implementation of output
management capabilities in the virtual backend, which is not helpful.

This change replaces it with a more useful test that verifies how
windows are placed after an output change.

e2a0863843 platforms/drm: more dynamic crtc assignment
Hardware constraints limit the number of crtcs and which connector + crtc
combinations can work together. The current code is searching for working
combinations when a hotplug happens but that's not enough, it also needs
to happen when the user enables or disables outputs and when modesets are
done, and the configuration change needs to be applied with a single atomic
commit.

This commit removes the hard dependency of DrmPipeline on crtcs by moving
the pending state of outputs from the drm objects to DrmPipeline itself,
which ensures that it's independent from the set of drm objects currently
used. It also changes requests from KScreen to be applied truly atomically.

ef72bae42f Introduce base InputDevice class
The main motivation behind this change is to prepare input abstractions
for virtual input devices so the wl_seat can properly advertise caps or
the cursor getting properly mapped/unmapped when a fake pointer is
added/removed on a system without a hardware mouse connected.

With this, there are three abstractions - InputDevice, InputBackend, and
InputRedirection.

An InputDevice represents an input device such as a mouse, a keyboard, a
tablet, etc. The InputBackend class notifies the InputRedirection about
(dis-)connected devices. The InputRedirection manages the input devices.

Such design allows to unify the event flow for real and virtual input
devices.

There can be several input backends active. For example, the libinput
backend and an input backend that provides virtual input devices, e.g.
libeis or org_kde_kwin_fake_input.

1330376220 screencast: Support the creation of virtual displays to cast
In case the user has just the one display but they don't want to show it
in their main workspace when sharing video, allow creating a virtual
display.
This also will allow using remote devices as support displays.

d228829abb Introduce Platform::outputAt()
With AbstractOutput being used more heavily, it makes sense to have
something like Screens::number() in the Platform class. As is, the steps
to get an output for a given point are awkward - first, get the screen
id, then use the screen id to get the output.

7f883fa724 Make EGL_KHR_surfaceless_context mandatory
We use surfaceless contexts with internal windows. We also require
the EGL_KHR_surfaceless_context extension for making context current
without outputs.

Arguably, we could use pbuffers, but since mainstream drivers (Mesa and
NVIDIA) support surfaceless contexts, the extra complexity doesn't buy
us anything.

e315b0f9fe Remove Platform::sceneEglConfig()
With per-screen rendering, every output may have different EGLConfig.
Having a single global EGLConfig doesn't work out well.

This change removes Platform::sceneEglConfig(). It's used primarily to
create the global share context. In hindsight, the global share context
can be created without EGLConfig as it's never made current.

EGL_NO_CONFIG_KHR is part of EGL_KHR_no_config_context extension, which
is supported by both Mesa and NVIDIA driver so it should be safe to make
it mandatory.

811beb94e0 Remove Xrender backend
The Xrender backend was added at the time when OpenGL drivers were not
particularly stable. Nowadays though, it's a totally different situation.

The OpenGL render backend has been the default one for many years. It's
quite stable, and it allows implementing many advanced features that
other render backends don't.

Many features are not tested with it during the development cycle; the
only time when it is noticed is when changes in other parts of kwin break
the build in the xrender backend. Effectively, the xrender backend is
unmaintained nowadays.

Given that the xrender backend is effectively unmaintained and our focus
being shifted towards wayland, this change drops the xrender backend in
favor of the opengl backend.

Besides being de-facto unmaintained, another issue is that QtQuick does
not support and most likely will never support the Xrender API. This
poses a problem as we want thumbnail items to be natively integrated in
the qtquick scene graph.

2742e5b422 Rearrange wayland startup sequence
The backend can now optionally wait for the scene to be created before
it updates its outputs, which is necessary for better atomic tests in
the DRM backend.

f46c7bae8d Move decoration renderer to decoration item
Currently, the implementation of the DecoratedClient and the decoration
renderer are strongly coupled. This poses a problem with the item based
design as the ultimate goal is to have scene items construct paint nodes
which are then fed to the renderer. The DecorationItem has to have
control over the decoration texture. Another issue is that the scene
cannot smoothly cross-fade between two window states if the decoration
is removed, e.g. from fullscreen mode to normal and vice versa.

This change moves the decoration renderer to the decoration item. With
the introduction of a generic scene texture atlas, we hope to get rid of
the decoration renderer altogether.

f8c00a530f Remove Platform::prepareShutdown()
Platform::prepareShutdown() was introduced to work around the issue
where the platform accesses destroyed OutputDeviceInterface objects.

Since we no longer query OutputDeviceInterface for output info, the
Platform::prepareShutdown() function can be dropped.

ade861d6de Refactor session code
At the moment, the session code is far from being extensible. If we
decide to add support for libseatd, it will be a challenging task with
the current design of session management code. The goal of this
refactoring is to fix that.

Another motivation behind this change is to prepare session related code
for upstreaming to kwayland-server where it belongs.

93e0265e4e Move source code to src/ directory
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.

This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.

We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
