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.

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.

ea1873f975 [effects/dimscreen] Port to JavaScript
Summary:
The ported effect looks quite similar to the C++ version except one
thing: it works correctly when user activates/deactivates a full
screen effect, for example the Desktop Cube effect.

Other than that, there are no behavioral or visual differences.

862bf0f153 [effects/scale] Port to JavaScript
Summary:
Now, when the scripting effects API has all required ingredients to port
the Scale effect to JavaScript we finally can do it.

The main rationale for porting this effect to JavaScript is that
scripted effects API lets us focus more on what we want instead of
"how".

Visually, the ported version doesn't deviate from the C++ version.

Test Plan:
* Enable the Scale effect;
* Open/close a window.

eb78b1ca3a [effects] Re-implement the Minimize Animation effect in JavaScript
Summary:
There were several reasons to rewrite the Minimize Animation effect in
JavaScript: to simplify code and to get rid of full repaints. One could
say that nothing prevents us from calculating the dirty region in
postPaintScreen or postPaintWindow and it is correct, but with the
scripting effects API the dirty region will be calculated for us, so we
can focus more on "what we want" instead of "how".

Visually, the "old" effect and the rewritten one look quite the same.
Except one tiny bit: if a window doesn't have an icon in the task manager,
it won't be animated. The reason for that is the purpose of this effect is
to show where the window will be after it's minimized, if the window
doesn't have icon in the task manager, one can't click at the center of
the screen to unminimize the window.

There is one significant change, the name of the effect was changed to
"Squash". If we put this effect and the Magic lamp effect under "Window
Minimize Animation" category (or if we add some "heading" label), then
the old name and the name of the category would "conflict". The new name
was suggested by Nate Graham and it very closely describes what the
effect does. "Scale" doesn't fit this effect because while a window is
being animated, its aspect ratio is not preserved.

9d197e8cb6 [effects] Add Scale effect
Summary:
The new effect scales windows as they appear and disappear.

As the the most of window animation effects, it is a monolithic effect,
i.e., if you enable scale effect, it will animate *both* the appearing and
disappearing.

The main difference between the Scale effect and the Scale in effect is
that the Scale in effect only animates windows as they appear. There is
no corresponding "the Scale out" effect, which is odd. Other points that
differentiate the Scale effect from the Scale in effect:

* it is more subtle;
* it doesn't animate the log out screen;
* it doesn't conflict with the Fade effect, etc.

... and overall, the Scale effect supersedes the Scale in effect.

//Window open animation.//

{F5904948}

//Window close animation.//

{F5905283, layout=center, size=full}

//KCM.//

Test Plan:
* Enabled this effect
* Opened/closed System Settings

2cc55e4077 [effects] Add a colorpicker effect
Summary:
The effect exports itself to DBus as object "/ColorPicker" and provides
an own interface "org.kde.kwin.ColorPicker".

It has one exported method to DBus "pick" which returns a QColor. When
invoked an interactive position picking selection is started. If it ends
the effect reads the color value at the picked position from the OpenGL
color buffer.

This implements T4568.

af80a546bf [effects] Drop the logout effect
Summary:
The new logout design doesn't want to have the vignetting. Thus the
logout effect itself doesn't make any sense any more. All that would
still be used is the logout blur which can also be provided by the
blur effect nowadays for fullscreen windows. As the new logout is a
fullscreen window it should use that one.

The logout effect did one more thing: it kept the vignetting and the
blur once the user selected logout. Now without the vignetting this
would be weird and again doesn't make much sense any more.

So overall I think it's better to just drop the logout effect and use
blur effect in normal way. Neat side advantage: it will also work on
Wayland out-of-the-box.

126263b6db Drop the Dashboard Effect
Basically dead code given that Plasma doesn't have a dedicated dashboard
mode anymore and also doesn't set the required window role for it to
work.

By deleting we save one string comparison for each newly opened window.

a784c91844 [kcmkwin/compositing] Use BuiltinEffects to find all built-in effects
The EffectData in BuiltinEffects is extended by all the data needed for
the desktop effects KCM:
* display name
* comment
* category
* video-url
* exclusive group
* internal

This information is taken directly from the desktop files.

The Built-in effects are now also resolved through the BuiltInEffects
namespace and the KServiceTypeTrader query is adjusted to only find the
scripted effects.

Unfortunately this introduces another round of adding "kwin4_effect_" to
load and save the effects correctly. This will be removed once all KCMs
are adjusted to use the new BuiltInEffects.

3e32bf9f56 Improve specifying the data about the built-in effects
Instead of having several hashes with data about the built-in effect,
we use a struct EffectData which contains the name, the enabled by
default state and function pointers to create, supported and check
enabled by default. There is one static vector with all the data
specified which is ordered by the BuiltInEffect enum. Thus an enum value
can be used as an index to the data.

In addition it's no longer resolved around QByteArray, but uses QString.

659b760355 [kwin] Rename BuiltInEffects::enabledByDefault to checkEnabledByDefault
The functionality is to check whether the effect should be enabled by
default. It's not about whether the effect is enabled by default. This
is also needed as it's currently still taken from the plugin data.

76efe517a7 Turn built-in effects into a library kwin links against
As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects

All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.

During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.

Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.

[1] QElapsedTimer around the loading code, start kwin five times, take
average.
