Summary:
The screenlock fails on X11 if it can't grab the keyboard.
We can't nicely solve the generic case. We can solve the common case of
a kwin effect being active.
It's not critical, arguably not even desirable to have these effects
persist after the screen is locked through an external trigger. We can
just close the effect early.
Key grabs have to be relased early before the close animation completes
so that the locker doesn't have a race based on animation times.
It's not ideal, but no worse than the current state for not much work.

Summary:
Plasma's Task manager exposes an optional feature whereby the user
can middle-click on a window to close it, but the Present Windows effect
does not do the same.
The presence of a close button you can left-click does not replace the desirable
feature to be able to middle-click on a window to close it, because then the
whole window becomes a click target, so it can be much much faster than
having to aim for the little close button. Also it's off by default, so a user
who goes out of their way to turn it on is signaling that they want to accept the
risk of accidentally closing a window by accident.
Finally, the feature is not allowed for left-click, so people can never accidentally
wreck Present Windows for themselves by assigning it to left-click by accident
and then mistakenly closing their windows.
This reverts commit 55585514f9.

Some old themes have the flag set and also a style which expects the

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.

Currently, we have three effects that can be used to animate the
appearing of toplevel windows(fade, glide, scale) and one can enable
all three of them, which seems to be wrong. It doesn't make sense to have
glide and scale effect enabled, for example.
We couldn't put all three effects into an exclusive group before because
the fade effect animates not only toplevel windows but also popups. So,
if all three effects are in an exclusive group and you enable glide effect,
for example, then tooltips and other popups won't be faded in/out.
This patch splits the fade effect into two: the first effect (called Fade)
animates toplevel windows and the other one (called Fading Popups) animates
popup windows.

Summary:
If you switch virtual desktops while krunner is sliding in, then
depending on whether your distro strips assert statements away,
KWin can crash.
The reason why it crashes is the sliding popups effect tries to unref
deleted windows that it hasn't referenced before (if there is an active
full screen effect, then popups won't be slided out, which in its turn
means that we won't reference deleted windows). So, in the end, the
refcount of those windows can be -1. That triggers an assert statement
in the destructor of the Deleted class, which checks whether the
refcount is equal to 0.
Popups are not slided while there is an active full screen effect because
we don't know what the full screen effect does.
This patch adjusts the sliding popups effect so it stops all active
animations when user switches virtual desktops or when a full screen
effect kicks in. We need to do that so the effect won't try to
unreference windows in postPaintWindow.
Visually, it doesn't look quite nice, but for now that's good enough.
A proper fix would be more complex: we would need to make sure that
full screen effects ignore sliding popups (and also maybe docks) and
perform some input redirection.

Summary:
When using the natural layout algorithm with the fill-gaps option, a small
error (less than one) is introduced in windows' aspect ratio each time they are
enlarged due to floating-point roundoff.
Currently, the algorithm computes the width and height enlargement factors and
then attempts to enlarge in each of the four possible directions, repeating
until it can't enlarge any windows any further. Hence, this aspect ratio error
can be multiplied by up to four. Especially for small, long, and narrow
windows, this can result in a total error of greater than one by the end of
that loop iteration. If this occurs, on subsequent iterations the height
enlargement factor might then be computed as negative violating some of the
core assumptions of the algorithm and resulting in the loop iterating endlessly
until one of the window dimensions overflows, freezing the program for up to
several minutes.
To fix this, the height enlargement factor should be re-computed based on the
new width each time the window is enlarged, ensuring the error introduced in
the aspect ratio never exceeds one.

Summary:
There were several reasons to rewrite the Minimize Animation effect in
JavaScript: to simplify code and to get rid of full repaints. One could
say that nothing prevents us from calculating the dirty region in
postPaintScreen or postPaintWindow and it is correct, but with the
scripting effects API the dirty region will be calculated for us, so we
can focus more on "what we want" instead of "how".
Visually, the "old" effect and the rewritten one look quite the same.
Except one tiny bit: if a window doesn't have an icon in the task manager,
it won't be animated. The reason for that is the purpose of this effect is
to show where the window will be after it's minimized, if the window
doesn't have icon in the task manager, one can't click at the center of
the screen to unminimize the window.
There is one significant change, the name of the effect was changed to
"Squash". If we put this effect and the Magic lamp effect under "Window
Minimize Animation" category (or if we add some "heading" label), then
the old name and the name of the category would "conflict". The new name
was suggested by Nate Graham and it very closely describes what the
effect does. "Scale" doesn't fit this effect because while a window is
being animated, its aspect ratio is not preserved.

Summary:
Background behind some windows is not blurred because the invert effect
sets PAINT_WINDOW_TRANSFORMED. This essentially "turns off" the blur and
the background contrast effect unless we set the force roles.
Because the invert effect is a "post-processing"(not really) effect we
don't have to set that flag.

Summary:
For some historical reasons, the sheet effect uses animation duration of
500ms. In comparison to other effects that animate the appearing and the
disappearing of windows, 500ms is too high value for the duration.
As the title says, this change decreases the default animation duration
to 300ms. The new duration is more saner.
The opacity is animated to make the effect look smoother with the
shorter animation duration.

Summary:
When using the natural layout algorithm with the fill-gaps option, a small
error (less than one) is introduced in windows' aspect ratio each time they are
enlarged due to floating-point roundoff.
Currently, the algorithm computes the width and height enlargement factors and
then attempts to enlarge in each of the four possible directions, repeating
until it can't enlarge any windows any further. Hence, this aspect ratio error
can be multiplied by up to four. Especially for small, long, and narrow
windows, this can result in a total error of greater than one by the end of
that loop iteration. If this occurs, on subsequent iterations the height
enlargement factor might then be computed as negative violating some of the
core assumptions of the algorithm and resulting in the loop iterating endlessly
until one of the window dimensions overflows, freezing the program for up to
several minutes.
To fix this, the height enlargement factor should be re-computed based on the
new width each time the window is enlarged, ensuring the error introduced in
the aspect ratio never exceeds one.

The most reliable way to reproduce the freeze seems to be to activate the
desktop-grid effect while a tool-tip window is fading in.
Ensure desktop-grid is configured to use present windows, and that present
windows is configured to use the natural layout algorithm with the fill gaps
option selected.
The freeze is still intermittent, but using this method should be able to be
triggered within about 10 tries without this fix.
After applying the fix, the freeze has never been observed.

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.

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.

It makes sense to cancel previously active animations because they have

The Show Paint effect is useful when debugging repaint regions issued by
effects. The only headache with it is necessity to enable/disable it.
Consider the following workflow:
* Do some change to an effect;
* Compile KWin (or the effect);
* Go to System Settings and enable the Show Paint effect;
* Test effect, check repaint regions, etc;
* Disable the Show Paint effect;
* Go to the step 1.
This workflow is really exhausting. Also, when testing repaints in a
nested compositor, things become quite messy.
Because purpose of this effect is to debug repaints (and because this
effect is not meant for daily usage), I think that's fine to change
how it's activated.
This patch improves the workflow by changing the way how this effect
gets activated. Instead of enabling/disabling it, one can just use a shortcut
to activate or deactivate the effect.

As well as background contrast effect.
This patch does the following thing:
- Adopted WindowForceBlur / WindowForceBackgroundContrast logic from SlideEffect, instead of panels/stickyWindows QSets (those become useless anyway)
- Added shouldAnimate code, which determines whether a window should be animated with the cube (i.e. ordinary windows) or should stick (i.e. panels or pinned windows, if corresponding options are checked in the settings)
- It paints an additional non-transformed screen, on which it paints only "sticky" windows. This is done because otherwise KWin would apply blur not behind the OSD, but on the same place on moving cube face.
- (in addition) switched to new Qt5 connect syntax.

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.

respectively. The Sliding popups effect doesn't fade windows, it slides
them;
(c) mWindowsData should be m_animationsData because other parts of this
effect refer to it as "anim data"(e.g. setupAnimData).
This effect uses its own Location enum class instead of KWayland::
Server::SlideInterface::Location because it would be better to not
depend on platform specific data structures.
As a side effect, this change also fixes QHash abuse. The Sliding popups
effect is still hashing windows twice in prePaintWindow and paintWindow.
But I think that's acceptable because usually there would be only one
active sliding window.

Summary:
Slided popups are clipped twice:
* first, when filtering window quads in prePaintWindow;
* then, when doing scissor test (the opengl scene plugin does scissor
test for transformed windows).
Because of that, we don't need to filter window quads. Filtering window
quads only adds overhead.
This change simplifies code and "fixes" incorrect clipping when a slided
popup has shadows.
Test Plan:
* Put Plasma panel on the left screen edge;
* Open and close the Application Launcher.
(repeat for top/right/bottom screen edge)

Summary:
The new effect scales windows as they appear and disappear.
As the the most of window animation effects, it is a monolithic effect,
i.e., if you enable scale effect, it will animate *both* the appearing and
disappearing.
The main difference between the Scale effect and the Scale in effect is
that the Scale in effect only animates windows as they appear. There is
no corresponding "the Scale out" effect, which is odd. Other points that
differentiate the Scale effect from the Scale in effect:
* it is more subtle;
* it doesn't animate the log out screen;
* it doesn't conflict with the Fade effect, etc.
... and overall, the Scale effect supersedes the Scale in effect.

Summary:
The Glide effect should not animate the Application Dashboard because
it's not an ordinary application or a dialog. Same applies to Kickoff,
panel popups, etc.
The most obvious solution would be to add "plasmashell plasmashell"
window class to the blacklist, but we still would like to animate some
of plasmashell's windows, for example, Empty Trash Bin confirmation
dialog (if the trash bin icon is on the desktop).
One could notice that the Empty Trash Bin confirmation dialog, Task
Manager Settings window, and other plasmashell's windows that we want
to animate have decorations. So, we can use that as a heuristic.
Test Plan: Opened/closed the Application Dashboard.

Summary:
If a modal window is near some of screen edges, it will be distorted
in undesired way when it's being animated.
In order to keep perspective distortions invariant, no matter where
the modal window is on the screen, we have to move that modal window
to the origin, scale it, rotate it, translate it, apply perspective projection,
and then move it back.
Test Plan:
* Opened Kate
* Opened "Open File" dialog (during the in animation, it was distorted as expected)
* Closed that dialog (during the out animation, it was distorted as expected)

Summary:
If both the Glide effect and the Sheet effect are enabled,
they will conflict. Expected behavior would be:
* the Sheet effect animates only modal windows;
* the Glide effect animates the rest of normal windows.
In order to resolve the conflict, the Sheet effect has to grab
modal windows. Because it's quite specialized effect, we have
to ignore whether modal windows have been grabbed by the
Glide effect.
Test Plan:
* Enabled both the Glide effect and the Sheet effect;
* Opened Kate;
* Opened "Open file" dialog;
* Closed the dialog.

Summary:
Currently, the fade effect animates both the appearing and the
disappearing of the logout screen. We don't want that because
the logout effect should do that.
D14582 addresses that problem by adding "ksmserver ksmserver" window
class to the blacklist of the fade effect. With that change, only the
logout effect animates the appearing of the logout screen. But there is
a problem... If user clicks the cancel button, the logout screen
instantaneously disappears, instead of smoothly fading out.
This change addresses that problem by adding "out" animation.
Depends on D14582

The appearing of the logout screen is animated by both the Fade effect
and the Logout effect. The former should not animate the logout screen
because that's the job of the latter.

We have two exclusive categories in the Appearance category:
minimize-animations and show-desktop. But it's hard to draw a line
between them, i.e. one can't say whether given effect belongs to the
minimize-animations category or to the show-desktop category.

It makes significant difference only when animation speed is set to
"Very slow".

- Set animation speed to "Very slow"(it scales animation durations by 20x);
- Minimize/uniminimize System Settings.
