Summary:
Present windows works as follows:
- It moves all windows about until nothing is overlapping with any
other window.
- This doesn't resize anything so ultimately we end up with a new
co-ordinate space that's bigger than the screen depending on the amount
of overlap.
- We then render this whole view transformed to the screen
The rectangle "bounds" is in overviewpixels, with "scale" being the
ratio to convert to screen pixels.
When adjusting the new bounds there's an attempt to centre align things.
As bounds is in "overviewpixels" we multiply references to the previous
bounds by scale, and divide everything through at the end. bounds.x/y
were missed.
This is mostly unoticable except on massive super-ultra-wide monitors
which will otherwise have a tendency to shift to the left.
Test Plan:
Kai created a whole new test framework for this code that copy pasted
this algorithm then showed mock windows as rectangles

The frames field stores timestamps of previous frames, not time between

This change doesn't attempt to make the show fps compute more accurate
performance metrics, e.g. how much times it takes to execute rendering
commands on the GPU, etc.

It prevents taking screenshots of missing Hidpi related bugs showing the issues under Wayland.
This fix the case of a single screenshot, but not the rest:
Multiscreen screenshot downscales the screen using scale factor.
Spectacle rectangular selection screenshot is broken as soon as some scale factor different than 1 is used on any screen.

The output image is not downscaled and has the same size as the screen resolution.
No other change to any other screenshot mode, or under X.

Because KWin is a very old project, we use three kinds of null pointer

This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

Doxygen comments with this style look balanced and neat, but many people

more traditional doxygen comment style, i.e.
/**

Reviewing such changes has been a bit frustrating for me (so selfish!)

This change switches doxygen comment style in KWin to a more traditional

for new contributors as well us.

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.
Test Plan: Compiles.

We can't nicely solve the generic case. We can solve the common case of

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.
