dffd9777c7 [libkwineffects] Make AnimationEffect::AniMap protected
Summary:
We need AniMap only for test purposes so it would be better to make the
typedef protected (and mark as internal as well).

    /** Foo bar.
     */

    /**

932ccb2ac3 Switch ThumbnailItem to internal uuid instead of WId
Summary:
So far the ThumbnailItem in TabBox mode used the window id for finding
the window it should render a thumbnail on. In the Wayland world this is
not unique. The window id could be either an X11 window or a wayland
window. We don't guarantee that there are no conflicting ids.

With the internal id we have a way to properly identify the windows, so
this element should use them.

To support this the property changed the type to QUuid and the
clientmodel also provides the QUuid. As in TabBox the way to get the
window is through the model this should be compatible for all themes.
It's tested and verified with the Breeze switcher.

For declarative KWin scripts the ThumbnailItem also provides the
AbstractClient as a property, so there should not be any script which
uses wid. If it does, this could break, but well the script should use
the intended API.

Test Plan: ctest passes, manual testing of Breeze alt-tab switcher

02a0561016 Add windowsystem plugin for KWin's qpa
Summary:
KWindowSystem provides a plugin interface to have platform specific
implementations. So far KWin relied on the implementation in
KWayland-integration repository.

This is something I find unsuited, for the following reasons:
 * any test in KWin for functionality set through the plugin would fail
 * it's not clear what's going on where
 * in worst case some code could deadlock
 * KWin shouldn't use KWindowSystem and only a small subset is allowed
to be used

The last point needs some further explanation. KWin internally does not
and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is
exposing information which KWin sets. It's more than weird if KWin asks
KWindowSystem for the state of a window it set itself. On X11 it's just
slow, on Wayland it can result in roundtrips to KWin itself which is
dangerous.

But due to using Plasma components we have a few areas where we use
KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in
direction, blur and background contrast. This we want to support and
need to support. Other API elements we do not want, like for examples
the available windows. KWin internal windows either have direct access
to KWin or a scripting interface exposed providing (limited) access -
there is just no need to have this in KWindowSystem.

To make it more clear what KWin supports as API of KWindowSystem for
internal windows this change implements a stripped down version of the
kwayland-integration plugin. The main difference is that it does not use
KWayland at all, but a QWindow internal side channel.

To support this EffectWindow provides an accessor for internalWindow and
the three already mentioned effects are adjusted to read from the
internal QWindow and it's dynamic properties.

This change is a first step for a further refactoring. I plan to split
the internal window out of ShellClient into a dedicated class. I think
there are nowadays too many special cases. If it moves out there is the
question whether we really want to use Wayland for the internal windows
or whether this is just historic ballast (after all we used to use
qwayland for that in the beginning).

As the change could introduce regressions I'm targetting 5.16.

Test Plan:
new test case for window type, manual testing using Alt+Tab
for the effects integration. Sliding popups, blur and contrast worked fine.

7834bec52a [libkwineffects] Replace property name lookup with calling the virtual methods
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

5e104fbc12 [scripting] Introduce redirect function
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.

e02573263f [libkwineffects] Introduce timeline redirect modes
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).

f521d4bbe1 [wayland] add enter/leave virtual desktop API
Summary:
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.

Test Plan:
testVirtualDesktops passes (with pending kwayland patch)
Moving a window in the desktop grid on X11 behaves

1b7cad95c7 [libkwineffects] Don't enable painting for windows that are not kept alive
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.

a281f2bce1 [effects/dialogparent] Fix flickering of parent windows
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.

769f2659dd [effects] Make Scale and Glide effects Wayland-friendly
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.

99b33e7428 [libkwineffects] Expose getting/setting activeFullScript to scripted effects
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.

BUG: 396790

This patch is against the QJSEngine port, though it's not conceptually a
requirement.

7b65aa9199 [libkwineffects] Remove broken copy constructor of AniData
This doesn't copy everything, it misses the ID which breaks
everything.

Given it's just a direct copy of members the auto-generated one does a

653e98d5ac [libkwineffects] Deprecate Outline feature
Summary:
KWin had Outline effect during KDE SC times, which had been removed in
KDE SC 4.11. With that effect, also showOutline and hideOutline signals
had been removed, making it impossible to write effects that show
outline. Yet, Outline enum value had been left.

Even though the Outline feature is useless nowadays, in order to keep API
compatibility, let's just deprecate it.

709b7c2c58 [libkwineffects] Push render targets more efficiently in GLRenderTarget::pushRenderTargets
Summary:
If s_renderTargets is not empty, GLRenderTarget::pushRenderTargets starts
to do pretty heavy things: it deletes head of the targets param in a while loop.

There is no need to do that. Because QStack inherits QVector, we can use
append method to push new render targets in a more efficient way.

Test Plan: Background behind Konsole is still blurred.

ee88951b17 [libkwineffects] Add TimeLine helper
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
timeLine.running(); // false
timeLine.done(); // false

timeLine.update(420);
timeLine.value(); // 0.42
timeLine.running(); // true
timeLine.done(); // false

timeLine.toggleDirection();
timeLine.value(); // 0.42
timeLine.running(); // true
timeLine.done(); // false

timeLine.update(100);
timeLine.value(); // 0.32
timeLine.running(); // true
timeLine.done(); // false

timeLine.update(1000);
timeLine.value(); // 0.0
timeLine.running(); // false
timeLine.done(); // true
```

Test Plan: Ran tests.

f977e60850 [libkwineffects] Save value of the managed property during construction of EffectWindow
Summary:
When windowClosed signal is emitted, effects can't distinguish managed
windows from unmanaged windows(e.g. combo box popups, popup menus, etc).
This leads to dirty hacks like IsXXXWindow. Also, there's a big chance
that such hack can introduce more bugs and overall this makes harder to
write/maintain effects.

This change proposes to save value of managed property during
construction of EffectWindow. So, its value is preserved with Deleted.

Test Plan: Manually.

95a2c3bf76 [libkwineffects] Emit a signal when active fullscreen effect changed
Summary:
Behaviour of some effects depends on presence of active fullscreen effect.
For example, Dim Inactive effect brightens windows if there is an active
fullscreen effect. If active fullscreen effect has been changed, these effects
might need to do some setup work, e.g. schedule repainting, toggle direction
of a timeline, etc.

For what it's worth, because the Dim Inactive effect doesn't schedule
repainting after leaving Desktop Grid, windows aren't dimmed back. One
need to move mouse to trigger dimming.
