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.

253ff428a7 [effects] Port to new connect syntax
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.

437a36a2bb [KScreen Effect] Fix fade to black
Summary:
When you have two windows ontop of each other and you turn them
transparent, evidently you'll be able to see through them.
Not only does it look unpolished if the desktop window flashes through
your windows, it can pose a privacy risk as you'd be able to briefly
look through the lock screen.

This patch fades apps to black intead of to transparent. As this looks
weird for panels, so windows are also faded to opaque (if relevant) at
the same rate.

90e77a939a [effects] Support xcbConnectionChanged for support properties
Summary:
Several effects announce a support property atom on the root window. This
change forwards the KWin::Application's signal that the xcbConnection
changed to the EffectsHandler so that the effects can respond to it.

All effects which announce a support property connect to this new signal
and re-announce the property. In case the xcb connection died (future
XWayland crashing case) it is set to XCB_ATOM_NONE by that. In case the
xcb connection got created (future delayed XWayland startup) the atom is
set to the proper value.

In addition all usages of the support properties are guarded, so that no
nonesense actions are performed if the support property is XCB_ATOM_NONE.

Test Plan: Only compile tested as we don't have XFree KWin yet

2132b1e0c8 [effects] Use arg="true" in the kcfg files
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.

4230a0d331 [effects] Get xcb_connection_t* and rootWindow through EffectsHandler API
So far the effects could just use the connection() and rootWindow()
provided by kwinglobals. Thus an internal detail from KWin core is
accessed directly.

To be more consistent with the rest of the API it's wrapped through the
EffectsHandler and with a convenient method in Effect.

The connection() is provided as xcbConnection() to free the very generic
name connection which could create confusion once we provide a wayland
connection to the Effects.

The rootWindow() is provided as x11RootWindow() to indicate that it is
for the X11 world.

77fff7af6a [kwin] Port away from deprected KCoreConfigSkeleton::readConfig
Most is just switched to the ::read(). That should be enough for all the
Effects which have a KSharedConfig::Ptr underneath. If not we just need
to find a good place to put the reload.

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.

category and compiled into the effects lib.

be3a0cf4ca Fix reading of window properties from effects
That's what you get for changing code you cannot properly test. The
calculation was completely messed up. Now reads the correct byte size
for the byte array. In addition the usages in the effects are improved
to cast the data into the proper uint32_t values instead of the more
generic long. After all if the format is 32, the length is 32 and not
a long.

76c207df09 Helper effect for KScreen integration
This effect is controlled by KScreen. It fades out all windows when
KScreen requests this and gives feedback to KScreen once all windows are
faded out. This allows KScreen to adjust the screens in a flicker free
way.
