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.
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.

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:
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:
Not only does the function windowsShareDesktop become a lot more complex
with the new desktop cardinality comparing if they share any desktop
isn't actually what we want.
If I have 2 windows on desktop 1 and the lower stacked window is also on
desktop 2, when I switch desktops the focus will change, but we don't
want to animate anything here as on this dekstop it has nothing to slide
in front of.
Instead this patch simply checks both windows are on the current
desktop.
Test Plan:
Loaded a few windows. Some on one, some on more.
Before if a window was on desktop 1&2 it wouldn't animate on 2.
Windows now seem to animate when they should and not when they shouldn't.

Summary:
Currently, effects like Maximize, Slide Back have problems with setting
WindowForceBlurRole. They store previous state of WindowForceBlurRole.
This is wrong. Instead they should either ignore previous state of
WindowForceBlur or refcount forced role.
There's no need for refcounting right now. For example, if several effects
force blur or background contrast, they are most likely in a conflict.
Please notice that the Desktop Grid effect uses the Present Windows
effect only to calculate transformations.
Some other problems with the code that sets WindowForceBlurRole:
* Maximize effect stores previous state of WindowForceBlurRole only
for one window. It ignores the fact that there could be several
active maximize animations;
* Desktop Grid/Present Windows/Slide back don't clean after themselves.
So, after using those effects for good amount of times, memory usage
will bump.
Test Plan:
* Enabled blur for Konsole
* Maximized Konsole
* Activated Present Windows
* Activated Desktop Grid
* Raised another window(to trigger Slide Back)

Summary:
The PresentWindows effect does not hide the window to close the selected
window. Instead it moves it outside the visible area. As this is a
"special" KWin window it is on top of the stacking order and needs to be
ignored in the slideback effect.
Instead of doing a special casing for this window the effect is changed
to ignore windows outside the visible area in general. Windows outside
the visible area just don't make sense to block the slideback effect.

Summary:
On Wayland it can happen that a window is still in the stacking order
although it is not visible. This is mostly the case for Plasma windows.
So far the slideback effect did not ignore those windows and as they are
higher in the stacking order than most other windows it blocked the
effect from working once a Plasma panel element got closed.
This change considers a window which has painting disabled in the
stacking order as not usable and thus filters out all those windows.

the stackingOrderChanged() signal came before the window turned an effect window
usually this is no problem as the change shall not be caught anyway, but
the window may have changed its stack position

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.

Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

This needs to be improved in core. Currently ClientGroup does not yet
emit signals, as it would be difficult to connect them. Nevertheless
the effects dependency should be removed.
EffectsHandlerImpl connects to the Workspace signal clientActivated.
The emitting of the signal is slightly moved from before the activation logic
to after the activation logic. This might change behavior in the scripting
component, but the previous code looked wrong.
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.
