Summary:
EffectWindow proxies its properties from the client/deleted's
properties.
QObject::property(char*) is a slow string search. It's a loop
of string comparisons not a hash lookup!
QML's use of properties is different, there's a property cache.
It's fetched multiple times for every window in every paint of some
effects (such as blur). Hotspot shows this as a significant amount of
the render pass (X11) with nothing in kwin animating.
This patch replaces the macro that does
parent()->property("propertyName")
with a macro calling the relevant function directly without metaobjects.
This also improves type safety for future changes.

Summary:
The redirect modes control behavior of the timeline when its direction
is changed at the start or target position. For example, consider the
following piece of code:
TimeLine timeLine(1000ms, TimeLine::Forward);
timeLine.setDirection(TimeLine::Backward);
What should happen when the direction of the timeline was changed to go
backward? Should the current value of the timeline go from 1 to 0, or
should the timeline stop its "execution"?
In the relaxed mode, the timeline will go from 1 to 0.
In the strict mode, the timeline will stop its execution.
Different effects may prefer different modes for source and target
positions. For example, most C++ effect would prefer relaxed mode for
source position, and strict mode for target position. On the other side,
scripted effects(AnimationEffect) would prefer strict mode for source
position, and relaxed mode for target position(because of set).

Summary:
As setDesktop was changed to "move" this left unSetDesktop non-symetric.
This replaces it with explicit API to enter/leave.
This also moves new API to the new object based API rather than still
using ints.
Where numbers are used it has been tidied up so that desktop IDs are
uint, which should be used when we have a list of desktops.
int is used only when we have either a desktop ID or NET::OnAllDesktops
(-1)
Effects API cleared up to use this and use a set of x11 IDs, which
avoids any potential complications of handling add and removes any
ambiguity with what happens if you leave all desktops and such.

With the plasma shell protocol, a ShellClient gets its role/window type
after it's created, so the cached value of the popupWindow property in
EffectWindow can be wrong.
In addition to that, the value of the popupWindow property still can be
wrong because plasma shell surfaces don't have xdg-popup role, so we need
to check NetWM-based window type in ShellClient::isPopupWindow.

Summary:
The Scale effect and the Glide effect have to animate only ordinary
windows(i.e. the ones that are considered to be apps).
On X11, in order to distinguish ordinary windows from combo box popups,
popup menus, and other popups, those effects check whether given window
is managed.
On Wayland, there is no concept of managed/unmanaged windows.
XDG Shell protocol defines 2 surface roles:
* xdg_toplevel;
* and, xdg_popup.
The former can be used to implement typical windows, the ones that can
be minimized, maximized, etc.
The latter can be used to implement tooltips, popup menus, etc. Thus,
that's a good criteria to filter popup windows.

Summary:
Most effects use QTimeLine in the following manner
```lang=cpp
if (...) {
m_timeline->setCurrentTime(m_timeline->currentTime() + time);
} else {
m_timeline->setCurrentTime(m_timeline->currentTime() - time);
}
```
Because effects do not rely on a timer that QTimeLine has, they can't
toggle direction of the QTimeLine, which makes somewhat harder to write
effects. In some cases that's obvious what condition to use to figure
out whether to add or subtract `time`, but there are cases when it's
not. In addition to that, setCurrentTime allows to have negative
currentTime, which in some cases causes bugs.
And overall, the way effects use QTimeLine is really hack-ish. It makes
more sense just to use an integer accumulator(like the Fall Apart
effect is doing) than to use QTimeLine.
Another problem with QTimeLine is that it's a QObject and some effects
do
```lang=cpp
class WindowInfo
{
public:
~WindowInfo();
QTimeLine *timeLine;
};
WindowInfo::~WindowInfo()
{
delete timeLine;
}
// ...
QHash<EffectWindow*, WindowInfo> m_windows;
```
which is unsafe.
This change adds the TimeLine class. The TimeLine class is a timeline
helper that designed specifically for needs of effects.
Demo
```lang=cpp
TimeLine timeLine(1000, TimeLine::Forward);
timeLine.setEasingCurve(QEasingCurve::Linear);
timeLine.value(); // 0.0
timeLine.running(); // false
timeLine.done(); // false
timeLine.update(420);
timeLine.value(); // 0.42
timeLine.running(); // true
timeLine.done(); // false
timeLine.toggleDirection();
timeLine.value(); // 0.42
timeLine.running(); // true
timeLine.done(); // false
timeLine.update(100);
timeLine.value(); // 0.32
timeLine.running(); // true
timeLine.done(); // false
timeLine.update(1000);

When windowClosed signal is emitted, effects can't distinguish managed
windows from unmanaged windows(e.g. combo box popups, popup menus, etc).
This leads to dirty hacks like IsXXXWindow. Also, there's a big chance

Summary:
When one uses:
* breeze as of 5.12
* wobbly windows
* shaded window
* a distribution building with assert enabled
and starts to move a shaded window, KWin asserts. The root cause for
this is that WindowQuad::makeSubQuad has an assert for y1 being smaller
than y2. With the combination listed above this is not guaranteed. For
the left shadow quad the y1 and y2 are identical and thus trying to
split it, results in the assert condition.
The problem of the shadow quad having an invalid size might be addressed
as well with D10811. Due to that the generation of the quads is not
touched. Instead a sanity check is introduced to not try to split
already invalid sized quads.

Summary:
On Wayland per output rendering is performed and paintScreen is invoked
for every output. Some effects need the information which output is
currently being rendered as otherwise e.g. FBO access could fail.
This change adds the current output geometry to ScreenPaintData. On X11
(all outputs one geometry) this information is not set and a null rect
is returned. That way the effects can also easily check which rendering
mode is used.

Summary:
So far TabBox used highlight windows by passing window ids around through
an X property. This doesn't work on Wayland where we don't have window
ids for our TabBox and the Wayland windows.
This change introduces a new Effect::Feature for HighlightWindows which
the HighlightWindowsEffect provides. The EffectsHandlerImpl has a new
method to highlightWindows which it delegates to that effect if it is
loaded by invoking a new performFeature method.
The TabBoxHandler now passes the highlighting to the effects system
instead of updating the x11 property. Thus this works on Wayland and
at the same time improves the X11 side by no longer having to go through
the property protocol.
Test Plan: Verified that Alt+Tab highlights the windows on Wayland correctly.

Summary:
The Effect class is extended by three new virtual methods:
* touchDown
* touchMotion
* touchUp
The methods return a boolean value so that the events can be filtered
out. E.g. an effect which has also a mouse grab installed wants to
filter out all events, other effects don't need the events exclusively.
This is a difference to how e.g. keyboard and pointer events are handled.
But is more close to how KWin's internal input event passing works and
makes it easier to get touch event: one does not explicitly has to grab
the events. It's also closer to Wayland where all input events are
available.
As a first example the Present Windows effect is adjusted and allows to
activate windows through the touch screen. As much code as possible is
shared with pointer input.

The screen projection matrix is needed if an effect wants to customize
the modelview projection matrix while rendering a window and keeping
the currently applied screen projection and transformation.
With this change a new ctor overload is added to ScreenPaintData
which allows passing a projection matrix through the effects. This
allows effects to put up custom shaders with a shared projection matrix
and without having to calculate it themselves.
The projection matrix is a read-only information for the effects. There
is no way to change or overwrite it.

-use qbytearray instead of qstring when dealing with latin1 input and output (glplatform)

Effects currently modify the matrices by reading back the uniform
values from the shader they assume will be used to paint the window,
set new values for the uniforms, call paintWindow(), and then restore
the uniforms to their previous values.
This is both slow and unreliable, and will not work with dynamically
generated shaders.
This patch solves the problem by putting the matrices in
WindowPaintData and making it the responsibility of the paintWindow()
implementation to set the uniforms.
Instead of getting size from displayWidth() and displayHeight() use
the information we have from Screens. This means there is only one
place to have the information and by that we can ensure that all
components use the same data to rely on. displayWidth/displayHeight
seem to provide the wrong information when unplugging an output
without disabling the output. This results in rendering artefacts.
But KWin::Screens has the correct information available.
When this property is true, it indicates that the +U axis corresponds
to the +Y axis, and the +V axis corresponds to the +X axis.
This property is taken into account in WindowQuad::makeSubQuad().
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.

A KWin::EffectPluginFactory is introduced which provides a specialized
create method and methods for the supported and enabledByDefault checks.
A set of KWIN_EFFECT_FACTORY macros are added which create a subclass
of this EffectPluginFactory following the approach from the
KPluginFactory macros. The macros only support json metadata thus the
QPluginTrader needs to be used.
The KWIN_EFFECT macros are removed as they are no longer needed.
KWin Core's loader is not yet adjusted to this change. This is a
preparation step for introducing a PluginEffectLoader.
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.
XRenderUtils are split out of kwineffects and are an own library just
like kwinglutils is an own library.
The library gets always build and is linked in KWin core unconditionally
(as it's used in outline) and conditionally in kwineffects (PaintClipper)
and the built in effects depending on XRender build option.
Instead of using EffectsHandler::sendReloadMessage we generate the dbus
interface in each plugin and call the reconfigure slot directly. That way
it's more type safe and we don't need to link kwineffects from the
configs.

Rational behind this change is that displayWidth and displayHeight are
X specific API calls in kwinglobals. For the future it's easier to only
rely on functionality which goes through the EffectsHandler API which
allows easier adjustments in KWin core.
displayWidth() and displayHeight() are only used to get the size or the
complete rect of all screens. This is also provided by:
effects->virtualScreenGeometry() or
effects->virtualScreenSize()

By setting the X property _KDE_NET_WM_SKIP_CLOSE_ANIMATION to 1 a window
can request to be excluded from any close animation. This property is
read in Toplevel, so that it is available to both Client and Unmanaged.
If the window has this property set the Scene suppresses the paintWindow
loop of the Deleted. Thus no effect needs to be adjusted. But an effect
using drawWindow directly would still be able to render the Deleted as
there is no suppression.
Furthermore the property is passed to the EffectWindow so that an
Effect can make use of this functionality and not start the animation
in the first place.

Client used to have dedicated methods for different icon sizes instead
of combining all pixmaps into one QIcon. This resulted in various parts
of KWin having different access to the icons:
* effects only got one pixmap of size 32x32
* decorations only got the 16x16 and 32x32 pixmaps combined into a QIcon
* tabbox could request all icon sizes, but only as pixmap
Now all sizes are available in one QIcon allowing to easily access the
best fitting icon in a given UI.
Instead of looping over every quad for every grid cell and checking
for possible intersections, loop over the quads once and compute
the top left corner of the first intersecting grid cell. Then loop over
all the intersecting cells from that point and create the sub quads.
This new algorithm also preserves the order of the quads in the
original list.
Port from kFatal to qFatal - kFatal is still in kde4support,
but lacking debug area support arguably isn't that big a
deal since fatals can't be turned off anyway.
