Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

We have lots of inconsistency at the moment in CMakeLists.txt files. Most
of it is due to kwin being a very old project. This change hopefully fixes

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.

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

Summary:
Effects that prefer to manipulate direction of animations sometimes need
to create animations in some particular state so later on they can be
played backward (swapping from and to is not enough and it would be wrong).
The proposed complete function lets such effects to fast-forward animations to
to the target position so they can be played backwards later on.

Summary:
Consider current implementation of the Squash effect: if a window was
minimized, an animation will be started; if the window is unminimized
and the animation is still active (that can happen when user clicks on
app's icon really fast), the animation will be stopped and a new one will
be created. Such behavior can lead to rapid jumps in the observed
"animation".
A better approach would be first try to **reverse** the already active
animation, and if that attempt wasn't successful, start a new animation.
This patch introduces a new function to the scripted effects API that
lets JavaScript effects to control direction of animations. The
prototype of the function looks as follows:
redirect(<animation id(s)>, <direction>, [<termination policy>])
the first argument is an animation id or a list of animation ids, the
second argument specifies the new direction of the animation or
animations if a list of ids was passed as the first argument. The
third argument specifies whether the animation(s) should be terminated
when it(they) reaches the source position, currently it's relevant only
for animations that are created with set() function. The termination
policy argument is optional, by default it's Effect.TerminateAtSource.
We can use this function to fix issues with rapid jumps in the Squash
effect. Also, redirect() lets us to write effects for simple animations
in slightly different style: first, we have to start the main animation
(e.g. for the Dialog Parent effect, it would be dimming of main windows)
and then change direction of the animation depending on external events,
e.g. when the Desktop Cube effect is activated.

Summary:
If a modal window is closed and some alternative effect that animates
the disappearing of windows is enabled(e.g. the Glide effect, or the
Scale effect), the Dialog Parent effect can cause flickering of the
parent window because its animation duration doesn't match duration of
those alternative effects.
Also, if the Fade effect, the Glide effect, and the Scale effect are
disabled, the Dialog Parent will keep the parent window alive for no
good reason.
This change addresses that problem by adding keepAlive property to
`animate` function so scripted effects have more control over lifetime
of animated windows.
If both a modal window and its parent window are closed at the same time
(and there is no effect that animates the disappearing of windows), the
Dialog Parent will stop immediately(because windowDeleted will be
emitted right after windowClosed signal).
If both a modal window and its parent window are closed at the same time
(and there is effect that animates the disappearing of windows), the
Dialog Parent won't reference the latter window. Thus, it won't cause
flickering. I.e. it will "passively" animate parent windows.

Summary:
Getter is exposed as a property on scripted effect in a way that hides
pointers from the scripting side.
Setter is implicitly handled as a property of newly created animations
and holds the activeFullScreenEffect whilst any of them are active. Like
existing effects it remains up to the effect author to avoid the
problems of multiple full screen effects. The RAII lock pattern is
somewhat overkill currently, but it's the direction I hope we can take
EffectsHandler in next API break.

Summary:
Qt render loops behave quite differently to each other.
KWin scripting as a workaround for another situation cleans
(17553e5a1f) handles tracking of script
windows by deleting the underlying window handle on hide.
This currently happens before the window gets the hideEvent.
Arguably this is a quirk with Qt, but in the current state:
- QSGThreadedRenderLoop deletes the platform window and cleans up
- We then get the hide() event. This no-ops because there's no window.
(else branch of case WM_TryRelease in qsgthreadedrenderloop.cpp)
- We carry on rendering animations despite having no platform
- undefined behaviour
Normally this isn't a problem as typically destruction of the platform window
happens only when a window is being deleted, we're messing with Qt
internals here.
If we make sure the QHideEvent is processed by the render loop first,
things seem fine.

By changing the loading of scripted effect config to interact with
kwinApp we broke the tests which do not use a kwinApp.
This change turns the access to the KSharedConfigPtr go through the
property system, so that the tests can also install a dummy
KSharedConfigPtr. With that scripted effects loader test passes and no
longer crashes and the integration/effects tests also still pass.
Summary:
So far ScriptedEffect used EffectsHandler::effectConfig to get the
KConfigGroup for the ScriptedEffect. This has the disadvantage that the
config file name is hardcoded to kwinrc in EffectsHandler::effectConfig.
Inside KWin a KSharedConfigPtr is used which can point to somwhere else
than kwinrc. If that was the case the ScriptedEffects were not able to
pick up this customized config and instead continued to read values from
kwinrc.
With this change the ScriptedEffects use the KSharedConfigPtr provided
by KWin. Thus in e.g. autotests we can use the general way to configure
the effects and don't need to write to the config.

Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.
This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.
As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.
The information whether animations are supported comes from the Scene.
It's implemented in the following way:
* XRender: animations are always supported
* QPainter: animations are never supported
* OpenGL: animations are supported, except for software emulation
In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.
