2d5482b013 plugins/x11: Emit outputAdded and outputRemoved
Currently, these two signals are emitted primarily only on Wayland, but
in order to have consistent core API, it's better to emit them on X11 too.

389407805c platforms/drm: Properly clean up the shadow framebuffer object
In case hardware transforms can be used again, the shadow framebuffer
must be destroyed; otherwise rendered results will be distorted due to a
mismatch between the dimensions of the shadow framebuffer and the mode
size.

b94c876597 Fix crash in eglTerminate()
At the moment, the gbm_device for the primary device is destroyed before
the EGLDisplay is destroyed. This results in a crash in Mesa.

In order to fix the crash, this change ensures that the EGLDisplay is
destroyed before the gbm device.

932cd27a5c plugins/screencast: Don't make effects opengl context current
This makes eglSwapBuffers() fail with per screen rendering enabled. In
long term, the screencast plugin has to create its own OpenGL context
and capture window frames after a compositing cycle has been performed.
However, it's currently tricky to do because of monitor screencasting.

bdfb946267 Convert Night Color into a plugin
Night Color adjusts the color temperature based on the current time in
your location. It's not a generic color correction module per se.

We need a central component that can be used by both night color and
colord integration to tweak gamma ramps and which will be able to
resolve conflicts between the two. The Night Color manager cannot be
such a thing because of its very specific usecase.

This change converts Night Color into a plugin to prepare some space for
such a component.

The tricky part is that the dbus api of Night Color has "ColorCorrect"
in its name. I'm afraid we cannot do that much about it without breaking
API compatibility.

cea2781318 screencating: query for dmabuf availability before we start streaming
As things are right now, we can only do 32bit textures for dmabuf (see
gbm_bo_format in gbm.h). This means that we were lying to our receivers
when we had 24bit textures by then giving a 32bit texture instead.

This changes it so we request a dummy texture before starting and if we
are offered one we assume they're available and offer a 32bits stream
directly (i.e. BGRA).

8f6edea521 Turn krunner integration into a plugin
krunner stuff doesn't really belong in kwin, it has nothing to do with
compositing or any other things that are the domain of compositors.

f037a69f1c Introduce colord integration
This change introduces basic colord integration in wayland session. It
is implemented as a binary plugin.

If an output is connected, the plugin will create the corresponding
colord device using the D-Bus API and start monitoring the device for
changes.

When a colord devices changes, the plugin will read the VCGT tag of the
current ICC color profile and apply it.

c766e5da6d Introduce infrastructure for compositor extensions
The scripting api is not suitable for implementing all features that
should not be implemented in libkwin. For example, the krunner
integration or screencasting are the things that don't belong to be
compiled right into kwin and yet we don't have any other choice.

This change introduces a quick and dirty plugin infrastructure that
can be used to implement things such as colord integration, krunner
integration, etc.

f3a902911a wayland: Link statically KWindowSystem integration plugin
Without the KWindowSystem integration plugin, Wayland experience will be

5e60e64a5d Bundle QPA plugin directly
On wayland, we know we're always going to load our internal QPA. Instead
of shipping a plugin and loading it dynamically we can use Qt static
plugins.

This should result in slightly faster load times, but also reduce the
number of moving pieces for kwin.

This also prevents anyone outside kwin loading our QPA which wouldn't
have made any sense and just crashed.

755dd81e49 Refactor how per screen rendering is handled
In order to allow per screen rendering, we need the Compositor to be
able to drive rendering on each screen. Currently, it's not possible
because Scene::paint() paints all screen.

With this change, the Compositor will be able to ask the Scene to paint
only a screen with the specific id.

3d43f8ad93 Drop QGraphicsView classes in PaintData
QGraphicsRotation and Scale are QObject wrappers. It's not useful in
data structures where we're creating mulitple of these every frame. It's
large enough to appear in hotspot as taking over 1% of a regular frame.

We don't even use the QGraphicsRotation mapping inside scene for a
reason, so it's not giving us much.

It's technically an API break in libkwineffects. Pragamatically no-one
would use these. We also lose QGraphicsScale's origin, but we never
exposed this in PaintData's public header.

74391e250e Store repaint regions per individual screen
AnimationEffect schedules repaints in postPaintWindow() and performs
cleanup in preScreenPaint(). With the X11-style rendering, this doesn't
have any issues, scheduled repaints will be reset during the next
compositing cycle.

But with per screen rendering, we might hit the following case

    - Paint screen 0
    - Reset scheduled repaints
    - AnimationEffect::prePaintScreen(): update the timeline
    - AnimationEffect::postPaintScreen(): schedule a repaint

    - Paint screen 1
    - Reset scheduled repaints
    - AnimationEffect::prePaintScreen(): destroy the animation
    - AnimationEffect::postPaintScreen(): no repaint is scheduled

    - Return to the event loop

In this scenario, the repaint region scheduled by AnimationEffect will
be lost when compositing is performed on screen 1.

There is no any other way to fix this issue but maintain repaint regions
per each individual screen if per screen rendering is enabled.
