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:
The new connect syntax has several advantages over the old syntax:
(a) Connecting with the new syntax is faster;
(b) It is compile time checked.
There are still a few places where the old connect syntax is used, e.g.
connecting to QML buttons in the Desktop Grid effect.
Test Plan:
Have been testing this patch for ~2 weeks, haven't noticed any
regressions.

Summary: This is second part of {D15175}, and aimed at fixing Bug 390366.
The problem was that effect relied on isManaged() to detect OSDs and notifications, that should be painted on top of the cube. On Wayland, the desktop window itself is not managed, which made it "sticky".
Instead we use isSpecialWindow() check to explicitly make notifications and OSDs sticky.
It still requires fixing Plasma::Dialog, since it does not set isSpecialWindow() flag correctly.

BUG: 390366
FIXED-IN: 5.15.0
Summary:
Bugs occurred because KWin was not very happy when windows were painted during CubeSlideEffect::paintScreen().
Another issue is that blur, although it was supposed to, did not work at all (haven't found appropriate bug on bugzilla).
As well as background contrast effect.
This patch does the following thing:
- Adopted WindowForceBlur / WindowForceBackgroundContrast logic from SlideEffect, instead of panels/stickyWindows QSets (those become useless anyway)
- Added shouldAnimate code, which determines whether a window should be animated with the cube (i.e. ordinary windows) or should stick (i.e. panels or pinned windows, if corresponding options are checked in the settings)
- It paints an additional non-transformed screen, on which it paints only "sticky" windows. This is done because otherwise KWin would apply blur not behind the OSD, but on the same place on moving cube face.
- (in addition) switched to new Qt5 connect syntax.

The main problem was that inside the effect there was manualVerticalAngle,
which did not represent the actual rotation angle of the cube during the
animation, but used to calculate the position of the reflection. The actual
angle was calculated on-the-fly and was not exposed outside.
Brief description of what the code does:
- variables currentAngle and verticalCurrentAngle now always represent the
current position of the cube. They are updated when one uses the mouse and
inside the rotateCube() method, which is called in prePaintScreen().
- two queues, animations (used for Start / Stop / Left / Right) and
verticalAnimations (used for Up / Down) are used for scheduling the animations
if i.e. user presses several keys in a row. The code checks whether the last
animation has finished (and thus we need to start a new one) inside
prePaintScreen() and postPaintScreen()
- when the animation starts, code saves the starting position of the cube
inside startAngle, startFrontDesktop and verticalStartAngle variables, which
are used to calculate the actual cube position during the animation later.
This is done by startAnimation() and startVerticalAnimation(), which also
calculates the QTimeLine curves needed for animation

Summary:
By changing all kcfg to have arg="true" we can pass in the same
KSharedConfigPtr into all effects. This allows to have fake config in
the tests and in the planned effect demo mode.
Also it means that we don't have to hardcode the name kwinrc into the
files. In the configs - where we cannot access the effectshandler - we
use the define KWIN_CONFIG which gets generated based on the compile
time arguments.

Typically after deselecting "Show caps" option, the associated options "Cap color" and "Display image on caps" are grayed out (triggered by signal). The bug was when Desktop Cube settings were closed and opened again then the options were not grayed out.
Succesfully compiled and tested by deselecting "Show caps" option in Desktop Cube settings, closing the settings window and opening it once again. The options "Cap color" and "Display image on caps" were then grayed out.

Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.
This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.
As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.
The information whether animations are supported comes from the Scene.
It's implemented in the following way:
* XRender: animations are always supported
* QPainter: animations are never supported
* OpenGL: animations are supported, except for software emulation
In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.

One resource is used for shader version 1.10 and one for version 1.40.
The ideas behind this change is to remove the locating of the shader
sources and also to fix that user provided shaders could be loaded
instead of the original ones (possible attack vector on Wayland).
To simplify the ShaderManager provides a new method call to load the
shader from the resource. This means the effects don't need to
duplicate the check for the shader version any more and also don't
need to duplicate the file reading functionality.

Most of those effects didn't need special screen locking handling on
X11 as they prevented screen locking. On Wayland though, we don't
want the lock screen shown on a cube.
