Summary:
When a plasma session quits, the order of plasmashell and clients quitting is undetermined.
This looks bad as our desktop background disappears quite early. Rather than changing the real order, we can have kwin reference the last pixmap of any desktop and hold on to it.
Lasting till the compositor quits means it stays on the X frontbuffer till X quits and the experience is seamless.
Test Plan: Logged out (with relevant other ksmserver patches)

Won't make things go much faster since everything that was
being passed by value is refcounted but still const & is a bit faster
than refcounting
For shared pointers instead of adding const & we move them into the
destination variable saving some cpu usage but at the same time making
clear the pointer is being stored by not being const &

Removes over 100 lines of rather confusing code, implicitly introduces a
sharedEngine. Doesn't perform hide/show by moving a window offscreen.
As for the freeze, proving that EffectQuickView covers this case without
lots of extra C++ is an important pre-requisite for ever moving this
effect to a magic declarative API.
General code structure remains the same.

Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
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).
Test Plan: Compiles.

Summary:
Wobbly Windows effect is capable of animating a window when it's shown

One needs to know how the effect works in order to enable these animations.
Therefore there's no good reason to keep these two animations because
practically no one uses them and they only add maintenance burden.

Summary:
So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
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.

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.
