1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

86b2b70458 [effects/wobblywindows] Remove traits of an open/close animation
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.

684b4b635e Use more traditional doxygen style
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.

8af2fa73dc Run clang-tidy with modernize-use-override check
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.

c2ffcfdc21 [effects/wobblywindows] Fix visual artifacts caused by maximize effect
Summary:
If one wants to drag a maximized window while he or she has enabled both
the Wobbly Windows and the Maximize effect, visual artifacts can be
shown.

When the Maximize effect animates transition from maximize to restore,
some parts of the window can overshoot repaint regions(because of
wobbliness), leaving us with the visual artifacts.

To fix that, we have to take into account current scale and translation
when calculating dirty region in the Wobbly Windows effect.

BUG: 370612
FIXED-IN: 5.14.1

Test Plan: When dragging maximized windows, there are no visual artifacts anymore.

fb69b791a1 Ensure that all Effects honour the grab roles correctly
Summary:
When windows get added some effects grab the window and want to be the
only one animating this window. For this the grab roles exists. An
effect being notified later on evaluates the grab state and does not
start the animation.

This process failed due to being dependent on the order the effects are
loaded. Window Added/Closed are signals emitted by EffectsHandler, thus
first come, first serve. The requested effect order does not play into
it.

Due to that it could happen that an Effect which should not animate,
started to animate as the grab was still there.

This change adds the possibility to be notified whenever the window data
changes. A new signal is added to EffectsHandler which is emitted
whenever the windowData changes. The interested effects connect to it
and cancel their (just started) animation for the window.

Adjusted effects are:
* ScaleIn
* Fade
* WobblyWindows

In case of WobblyWindows an additional logical error was fixed that the
animations were only run when an effect grabbed instead of the other way
around.

FIXED-IN: 5.8.4

3bbc9436db [kwin] Add a virtual Effect::requestedEffectChainPosition
This method replaces the X-KDE-ORDERING property in the Effect's desktop
files. This change is a preparation step for integrating the new Effect
Loader which doesn't read the ordering information. Thus it needs to be
provided by the Effect itself so that the EffectsHandler can properly
insert it into the chain.

Also for the built-in Effects on the long run it doesn't make much sense
to install the desktop files. And binary plugin effects will migrate to
json metadata which also doesn't have the KService::Ptr. Thus overall it
simplifies to read this information directly from the Effect.

23f2de009b Effects can provide support information through properties
The supportInformation is extended to also read the properties
on all effects. In addition each effect can be queried just for
itself through D-Bus, e.g.:
qdbus org.kde.kwin /KWin supportInformationForEffect kwin4_effect_blur

All effects are extended to provide their configured and read
settings through properties. In some cases also important
runtime information is exposed.

that is transforming windows or painting or screen or doing anything

32c903b05b Rework signals for move/resize windows
First a signal is emitted when the user starts a move/resize operation.
During the move/resize operation each geometry change emits an update signal.
Last but not least a finish signal is emitted.

This eliminates the specific method for geometry updates in drawbound resize
mode.

909a678e13 New signal for maximize state changed
The signal includes the state for horizontal and vertical maximize state.
It would be better to use the enum fro, KDecorationDefines but we don't want
to depend on decorations library.

Wobbly windows is adjusted to use this new signal - it is the only effect
interested in maximize state change.

0b85768ec5 EffectsHandler emits windowClosed signal

ab6f2ba1fd EffectsHandler emits windowAdded signal
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.

0c166b6ecb call the windowUserMovedResized hook for maximize/restore. That method has two boolean parameters which indicate whether this is the first move in a sequence, and the last. For maximize/restore we set both to true, and several effects need tweaking to handle this case. Also include an addition to the wobbly windows effect to include a slight 'throb' when maximized/restored. This makes it easier for your eye to track where your de-maxized window went to.
