9f2cb0ae1b Provide expected presentation time to effects
Effects are given the interval between two consecutive frames. The main
flaw of this approach is that if the Compositor transitions from the idle
state to "active" state, i.e. when there is something to repaint,
effects may see a very large interval between the last painted frame and
the current. In order to address this issue, the Scene invalidates the
timer that is used to measure time between consecutive frames before the
Compositor is about to become idle.

While this works perfectly fine with Xinerama-style rendering, with per
screen rendering, determining whether the compositor is about to idle is
rather a tedious task mostly because a single output can't be used for
the test.

Furthermore, since the Compositor schedules pointless repaints just to
ensure that it's idle, it might take several attempts to figure out
whether the scene timer must be invalidated if you use (true) per screen
rendering.

Ideally, all effects should use a timeline helper that is aware of the
underlying render loop and its timings. However, this option is off the
table because it will involve a lot of work to implement it.

Alternative and much simpler option is to pass the expected presentation
time to effects rather than time between consecutive frames. This means
that effects are responsible for determining how much animation timelines
have to be advanced. Typically, an effect would have to store the
presentation timestamp provided in either prePaint{Screen,Window} and
use it in the subsequent prePaint{Screen,Window} call to estimate the
amount of time passed between the next and the last frames.

Unfortunately, this is an API incompatible change. However, it shouldn't
take a lot of work to port third-party binary effects, which don't use the
AnimationEffect class, to the new API. On the bright side, we no longer
need to be concerned about the Compositor getting idle.

We do still try to determine whether the Compositor is about to idle,
primarily, because the OpenGL render backend swaps buffers on present,
but that will change with the ongoing compositing timing rework.

1fb9f6f13a Switch to SPDX license markers
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.

dbac4bce7e Reduce the amount of objects that are compiled several times
Summary:
We build some objects several times which makes it uncomfortable to develop KWin
since every time we modify something a lot of things get rebuilt. This should
help a bit although it doesn't solve all the problems.

684b4b635e Use more traditional doxygen style
Summary:
So far we were following a bit unique and rare doxygen comment style:

    /**
     * Contents of the comment.
     **/

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

597445e2a6 [effects/diminactive] Add option to exclude fullscreen windows from dimming
Summary:
Such an option would be useful for people that are used to watch videos
in the fullscreen mode.

By default, we still dim fullscreen windows because watching videos in
fullscreen mode is not the only one use-case. One could have a text
editor in fullscreen mode on one screen and Konsole on another screen.
In that case, it would be desired to dim the text editor if the latter
is active. Also, because we don't have stats of how the fullscreen mode
is used by KDE Plasma users.

BUG: 399822
FIXED-IN: 5.15.0

Test Plan:
* Unchecked the "Fullscreen windows" checkbox;
* Opened Konsole;
* Opened Firefox in the fullscreen mode;
* Pressed Alt+Tab;
* (Firefox stayed bright)

396f8f558c [effects/diminactive] Delete active transitions when window is deleted
Summary:
The Dim Inactive effect expects that the windowClosed signal always
proceeds the windowDeleted signal. But in some cases that's not the case.

If a window gets destroyed before becoming ready for painting, only
the windowDeleted signal will be emitted. In addition to that, KWin will
activate that window, which means we'll probably start a transition for
it.

Because this effect cannot terminate active transitions for such
windows, KWin can crash in postPaintScreen.

This change addresses the crash in postPaintScreen by adding extra clean
up stuff in the windowDeleted slot to make sure that there are no
transitions for deleted windows.

The proper fix would be to not emit windowActivated signal for windows
that are not ready for painting.

BUG: 399612
FIXED-IN: 5.14.1

Test Plan:
Ran
```
x <- seq(5, 15, length=1000)
y <- dnorm(x, mean=10, sd=3)
plot(x, y, type="l", lwd=1)
```
in RKWard multiple times.

defa1061af [effects/diminactive] Fix initialization of m_activeWindow on reconfigure
Summary:
The Dim Inactive effect sees the world a little bit differently.
m_activeWindow is currently active window that can be dimmed later on.
In most cases, it's the same as effects->activeWindow(). In rare cases,
it can be nullptr, even when effects->activeWindow() is not equal to nullptr
(e.g. when active window is a context menu popup).

canDimWindow is a helper that returns true if a given window should be
dimmed, otherwise it returns false. It has one special case: if a given
window is equal to m_activeWindow, return false. I.e. don't dim active
windows.

Currently, if user changes config of this effect, active window becomes
dimmed.

The reason for that is we hit that special case when deciding whether
effects->activeWindow() should be m_activeWindow.

This change addresses that problem by resetting m_activeWindow so we
don't hit that special case.

Test Plan:
* Opened KCM of this effect;
* Changed strength;
* (the KCM window stayed bright after I clicked "Apply" button).

(everything else works as expected)

5165ee45b5 [effects] Rewrite the Dim Inactive effect
Summary:
The Dim Inactive effect was rewritten mostly to fix most of issues with
it, e.g. after leaving a full screen effect(e.g. Desktop Grid) windows
sometimes are not dimmed back, or when a window becomes inactive there
is no smooth transition, etc.

{F5956124}
//Before: the window is not smoothly dimmed.//

{F5956127}
//After: the window is smoothly dimmed.//

In combination with an effect that animates the disappearing of windows,
e.g. Glide, the rewritten Dim Inactive effect doesn't "flash" windows.
If an active window has been closed, it will stay bright. If an inactive
window has been closed, it will stay dimmed.

Among other changes, the KCM has been re-designed to follow common KCM
design in Plasma:

{F5956128, layout=center, size=full}

The way the rewritten Dim Inactive effect handles flashing/flickering problem can be
reused in the Dialog Parent effect.

### Demo

{F5959885}
//Before: dimming of a window group.//

{F5959886}
//After: Dimming of a window group.//

Depends on D13740

CCBUG: 359251

Test Plan:
Test plan #1
* Activated the Desktop Grid effect
* Dimmed windows smoothly brightened
* Left desktop grid
* Windows dimmed back

Test plan #2
* Opened Dolphin and its Preferences window
* Clicked on desktop, both Dolphin and the Preferences window dimmed
* Clicked on Dolphin, both windows smoothly brightened back

2132b1e0c8 [effects] Use arg="true" in the kcfg files
Summary:
By changing all kcfg to have arg="true" we can pass in the same
KSharedConfigPtr into all effects. This allows to have fake config in
the tests and in the planned effect demo mode.

Also it means that we don't have to hardcode the name kwinrc into the
files. In the configs - where we cannot access the effectshandler - we
use the define KWIN_CONFIG which gets generated based on the compile
time arguments.

3bbc9436db [kwin] Add a virtual Effect::requestedEffectChainPosition
This method replaces the X-KDE-ORDERING property in the Effect's desktop
files. This change is a preparation step for integrating the new Effect
Loader which doesn't read the ordering information. Thus it needs to be
provided by the Effect itself so that the EffectsHandler can properly
insert it into the chain.

Also for the built-in Effects on the long run it doesn't make much sense
to install the desktop files. And binary plugin effects will migrate to
json metadata which also doesn't have the KService::Ptr. Thus overall it
simplifies to read this information directly from the Effect.

* add_subdirectory is used for all effects which have a config module
* toplevel CMakeLists.txt contains the sources again for the effects
  which have a config module, but effects which don't have a config
  module are still included and thus the macro is still used
* plugin created for the config module, name pattern is:
   kwin_effectname_config
* plugin installed to ${PLUGIN_INSTALL_DIR}/kwin/effects/configs
* desktop file adjusted to new plugin name and keyword removed
* desktop file converted to json as meta data and no longer installed
* Uses K_PLUGIN_FACTORY_WITH_JSON

76efe517a7 Turn built-in effects into a library kwin links against
As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects

All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.

During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.

Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.

[1] QElapsedTimer around the loading code, start kwin five times, take
average.
