Summary:
EffectWindow proxies its properties from the client/deleted's
properties.
QObject::property(char*) is a slow string search. It's a loop
of string comparisons not a hash lookup!
QML's use of properties is different, there's a property cache.
It's fetched multiple times for every window in every paint of some
effects (such as blur). Hotspot shows this as a significant amount of
the render pass (X11) with nothing in kwin animating.
This patch replaces the macro that does
parent()->property("propertyName")
with a macro calling the relevant function directly without metaobjects.
This also improves type safety for future changes.

Effects that prefer to manipulate direction of animations sometimes need

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:
The redirect modes control behavior of the timeline when its direction
is changed at the start or target position. For example, consider the
following piece of code:
TimeLine timeLine(1000ms, TimeLine::Forward);
timeLine.setDirection(TimeLine::Backward);
What should happen when the direction of the timeline was changed to go
backward? Should the current value of the timeline go from 1 to 0, or
should the timeline stop its "execution"?
In the relaxed mode, the timeline will go from 1 to 0.
In the strict mode, the timeline will stop its execution.
Different effects may prefer different modes for source and target
positions. For example, most C++ effect would prefer relaxed mode for
source position, and strict mode for target position. On the other side,
scripted effects(AnimationEffect) would prefer strict mode for source
position, and relaxed mode for target position(because of set).

As setDesktop was changed to "move" this left unSetDesktop non-symetric.
This replaces it with explicit API to enter/leave.
This also moves new API to the new object based API rather than still
using ints.
Where numbers are used it has been tidied up so that desktop IDs are
uint, which should be used when we have a list of desktops.
int is used only when we have either a desktop ID or NET::OnAllDesktops
(-1)
Effects API cleared up to use this and use a set of x11 IDs, which
avoids any potential complications of handling add and removes any
ambiguity with what happens if you leave all desktops and such.

Summary:
862bf0f153 introduced a regression(sorry
for that): if you close a confirmation dialog(with the Scale effect and the
Dialog Parent effect being enabled), the main window(s) will flicker.
That flickering happens because the C++ version of the Scale effect and
AnimationEffect unref deleted windows in different places. AnimationEffect
unrefs deleted windows in prePaintScreen, which btw is not the best
place to do that. The C++ version unrefed windows in postPaintScreen.
So, when the Scale effect has finished animating the main windows, it
will unref them, but windowDeleted signal won't be emitted immediately.
Which means that the Dialog Parent won't be able to delete corresponding
animations on its side and main windows will be painted for a single
frame.
This change addresses flickering by adjusting prePaintWindow in
AnimationEffect so deleted windows won't be painted if none of
animations keeps them alive.
Test Plan:
(make sure that both the scale and the dialog parent effect are enabled)
* Go to System Settings > Application Style > Window Decorations;
* Select a decoration that is different from the current;
* Close the system settings window (don't click "Apply" button);
* When a dialog is shown, click "Discard" or "Apply" button.

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:
The Scale effect and the Glide effect have to animate only ordinary
windows(i.e. the ones that are considered to be apps).
On X11, in order to distinguish ordinary windows from combo box popups,
popup menus, and other popups, those effects check whether given window
is managed.
On Wayland, there is no concept of managed/unmanaged windows.
XDG Shell protocol defines 2 surface roles:
* xdg_toplevel;
* and, xdg_popup.
The former can be used to implement typical windows, the ones that can
be minimized, maximized, etc.
The latter can be used to implement tooltips, popup menus, etc. Thus,
that's a good criteria to filter popup windows.

Getter is exposed as a property on scripted effect in a way that hides

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:
Most effects use QTimeLine in the following manner
```lang=cpp
if (...) {
m_timeline->setCurrentTime(m_timeline->currentTime() + time);
} else {
m_timeline->setCurrentTime(m_timeline->currentTime() - time);
}
```
Because effects do not rely on a timer that QTimeLine has, they can't
toggle direction of the QTimeLine, which makes somewhat harder to write
effects. In some cases that's obvious what condition to use to figure
out whether to add or subtract `time`, but there are cases when it's
not. In addition to that, setCurrentTime allows to have negative
currentTime, which in some cases causes bugs.
And overall, the way effects use QTimeLine is really hack-ish. It makes
more sense just to use an integer accumulator(like the Fall Apart
effect is doing) than to use QTimeLine.
Another problem with QTimeLine is that it's a QObject and some effects
do
```lang=cpp
class WindowInfo
{
public:
~WindowInfo();
QTimeLine *timeLine;
};
WindowInfo::~WindowInfo()
{
delete timeLine;
}
// ...
QHash<EffectWindow*, WindowInfo> m_windows;
```
which is unsafe.
This change adds the TimeLine class. The TimeLine class is a timeline
helper that designed specifically for needs of effects.
Demo
```lang=cpp
TimeLine timeLine(1000, TimeLine::Forward);
timeLine.setEasingCurve(QEasingCurve::Linear);
timeLine.value(); // 0.0

this is that WindowQuad::makeSubQuad has an assert for y1 being smaller
than y2. With the combination listed above this is not guaranteed. For
the left shadow quad the y1 and y2 are identical and thus trying to
split it, results in the assert condition.
The problem of the shadow quad having an invalid size might be addressed
