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)

On one of my systems XKB_DEFAULT_LAYOUT is set to "de". This makes a few
tests fail, e.g. pointer input and modifier only shortcuts.
The reason is that those tests assume the xkb default layout behavior,
that is how xkb functions without any layout being set. So having the
env variable around influences the layout generation.
To prevent this the environment variables are unset and thus a
reproducable environment is created.

Summary:
So far KWin did not re-evaluate the window rules when the Client's
window class changes. Window class is the main (static) feature the rule
selection is based on. For dynamic changing mapping features like caption
KWin does re-evaluate the rules.
The reason for KWin to not evaluate when the class changes is that KWin
expects the class not to change. From ICCCM section 4.1.2.5:
> This property must be present when the window leaves the Withdrawn
> state and may be changed only while the window is in the Withdrawn
> state. Window managers may examine the property only when they start
> up and when the window leaves the Withdrawn state, but there should be
> no need for a client to change its state dynamically.
Unfortunately there are prominent applications such as Spotify which
violate this rule and do change the window class dynamically. While this
is a clear ICCCM violation there is nothing which really forbids it (may
not != must not) and nothing which forbids KWin to react on changes.
As also libtaskmanager started to react on it, it makes sense to also
hook up the required bits for window rules. After all KWin detects
changes to the window class for some time already and has the
functionality to evaluate the rules. So all there is, is one connect
which improves the situation for our users, while at the same time it
should be rather risk free. If a setup window rule breaks after this
change it's due to the client not being ICCCM compliant.
Test Plan:
I don't use any of the affected applications, so it's only
tested with the new added unit test.

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:
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:
A window maximising is an async operation. We work out what size we want
the client to be, then request the client to update. The window isn't
really maximised until we get that new buffer with the new size.
This patch splits the requested, pending and current state, updating as
appropriate.
Things are a bit complex with things like borders. Technically we
shouldn't update them till we get a response, but we also need to have
the correct geometry of the full size window in our request. For now
they behave as before, updating when we request the change.
X code is untouched.
This hopefully fixes maximise animations on wayland as now we update the
geometry before emitting maximisedChanged.

Summary:
When we want to change a client's size and position together we have to
request the client becomes a new size and only then move the window to
the new location.
Currently we process the new position the next time the buffer updates,
but with no guarantee that it has actually tried to resize/whatever yet.
The client could be providing a new buffer just because the contents
have changed.
XDGShell has an acked serial designed to keep everything precisely in
sync. A surface represents the last configure that was acked.
This patch tracks the pending position for each configure and applies it
accordingly.
WL_shell does not have this mechanism, so behaviour is kept the same as
before.
----
This is a pre-requisite to syncing maximisedState/isFullScreen with the
configure request.
Potentially we could remove the isWaitingForResizeSync checks when
resizing and it will still resize smoothly.

Current implementation of buildQuads assumes that corner shadow tiles
are always present:
const QRectF leftRect(
topLeftRect.bottomLeft(),
bottomLeftRect.topRight());
but that assumption is wrong. For example, if the default panel is on
the bottom screen edge, then the calendar popup won't have the
bottom-left shadow tile(at least on Wayland). Which means that the left
shadow tile won't be visible because
topLeftRect.left() == bottomLeftRect.right().
Corner rectangles only have to influence height of the left/right tile
and width of the top/bottom tile. Width of the left/right tile and
height of the top/bottom tile should not be controlled by corner tiles.
Overall, this is how shadow quads are computed:
* Compute the outer rectangle;
* Compute target rectangle for each corner tile. If some corner tile is
missing, move the target rectangle to the corresponding corner of the
inner shadow rect and set its width and height to 0. We need to do
that to prevent top/right/bottom/left tiles from spanning over
corners:

We would rather prefer something like this if the top-left tile is
missing:

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;

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
```

Summary:
This patch changes KWin's pointer constraining behavior by only allowing
constraints if the surface has keyboard focus. In case the client activation
state changes, it rechecks it.
Test Plan:
Manually with the pointer constraints test application and opening the
launcher by pressing meta. Also amended autotest.
