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.

FIXED-IN: 5.15.0
Test Plan:
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.

We don't really have to have two different code paths for group

In long term, we need to "invert" the relationship, instead of checking
whether given parent window has a transient, we should check whether
given transient is a transient for a given window so we can keep Deleted
transients above their old parents.

Such an option would be useful for people that are used to watch videos

By default, we still dim fullscreen windows because watching videos in
fullscreen mode is not the only one use-case. One could have a text
editor in fullscreen mode on one screen and Konsole on another screen.
In that case, it would be desired to dim the text editor if the latter

is used by KDE Plasma users.

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:
Previously when updating the state we would send a configure event with
the size 0,0. This means the client chooses the size. For regular window
this works as most toolkits treat this to mean the size that we
previously requested. It's not explicit in the spec either way.
For maximised windows it's a problem, the spec clearly states that when
maximised clients must follow the size given. Telling the client to be
0,0 doesn't make sense.
By always sending our last requested size we remove any ambiguity.

When the Maximize effect animates transition from maximize to restore,

wobbliness), leaving us with the visual artifacts.
To fix that, we have to take into account current scale and translation

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.

Summary:
If a window is being slided in and for some reason it gets closed, the
window will be slided out. The problem is that there is a jump between
the slide in animation and the slide out animation.
The reason for that is we cancel the slide in animation when the slide
out animation is started.
It makes sense to cancel previously active animations because they have
different durations. But visually, it doesn't look good.
TimeLine tries to preserve progress value when changing duration. Thus,
let's utilize that to fix the jump.
This change matters only with animation speed factor > 1.0.
