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.

We have lots of inconsistency at the moment in CMakeLists.txt files. Most
of it is due to kwin being a very old project. This change hopefully fixes
all of it.
Summary:
This has been commented out since 2014, I doubt it will come back.
This is a big amount of code, maintenance will be easier without it.

Summary:
Wobbly Windows effect is capable of animating a window when it's shown
or hidden. However, this feature has been hidden since it was added.
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.

Switch to Q_ASSERT in order to make code a bit more consistent. We have

distributions like Ubuntu don't strip away assert(), let's hope that
things are a bit different with Q_ASSERT.

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.

Summary:
Some old themes have the flag set and also a style which expects the
borders to be stretched. Given that the documentation on techbase
describes widgets/glowbar still as "a frame without a prefix", one also
would assume that all the optional hints (which make sense) still apply.
Even more, the Air & Oxygen themes have the hint also set, though for
their rendering it makes no difference.
The small code needed seems worth the unbreaking of old themes as well
as giving theme creators another variable of freedom for their styles.
Test Plan:
Glow bar still works on all corners and edges with all themes as before,
though rendering now as expected for themes which have the
"hint-stretch-borders" set.
