Summary:
Currently, when the user is moving a window in the desktop grid it is drawn from
the paintScreen function to ensure it appears above all other windows. However,
when drawing the window, the screenProjectionMatrix for the WindowPaintData structure
is never specified. Because of this, the window will not be visible if OpenGL
compositing along with Lanczos scaling are in use since its coordinates will never
be projected into screen-space (unless the window is maximized, in which case the
scaling code is bypassed).
BUG: 361371
BUG: 364509
FIXED-IN: 5.14.3
Test Plan:
Ensure OpenGL compositing is enabled and the scaling method is set to "Accurate" on
hardware supporting this option. Additionally, ensure the desktop grid effect is
active and is configured to use Present Windows. Open a window and ensure is it not
maximized. Click on the window and drag it around - its contents should remain visible
the entire time and follow the mouse.

Summary:
If the Desktop Grid effect doesn't use the Present Windows effect to
layout windows, windowAt helper can return a window that doesn't belong
to current activity because it doesn't check whether that window belongs
to current activity.
This change addresses that problem by adding corresponding check.

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:
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.

Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
* swipe up: Desktop Grid
* swipe down: Present Windows
* swipe left: previous virtual desktop
* swipe right: next virtual desktop
The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.
The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.
The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
* started: when the Gesture gets considered for a sequence
* cancelled: the Gesture no longer matches the sequence
* triggered: the sequence ended and the Gesture still matches
The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

Summary:
Desktop Grid has a feature that right or middle clicking a window toggles
the on all desktop state. If that is done for a desktop window, things
obviously start to fail.
KWin internally allows to change virtual desktop for all windows, even
for windows like the desktop or docks. Changing in KWin core is not a
solution.
Thus a special casing in desktop grid is added to disallow the selection
for desktop windows.

Summary:
This reverts commit 14d1fdf63f.
The zoom effect is definitely the wrong way, it's broken (can be
triggered without moving the mouse, expands windows outside of their
allotted area (looks like broken sizing/placement), isn't animated so
feels very choppy, isn't using well-known highlight semantics), the
result is that it feels unnatural and jarring. To be honest, when I
looked at it, I was looking for a bug in the code, e.g. margins not
being taken into account. It didn't come up in me that this could be
wanted behavior, until I read the code.
As to the original commit message: The highlight is useless for this
case, as any window can be dragged or activated, highlighted or not.
What *could* work is to somehow intensify the colors, but that again
would have to be animated, and play well with the ongoing desktop-zoom
animation, the mouse pointer location changes relative to the window, so
it's really complex to get right. I thought of this for a while, I don't
think the complexity that has to be implemented is worth the benefit,
because, what does highlighted really mean here? "window is under the
mouse" isn't a useful metric, as we don't know if the user is changing
desktops or rearranging windows, and "window under mouse" changes
depending on the zoom level, "window can be dragged or activated" also
isn't a useful metric, as I can do that with any window, anyway.
Test Plan: Tested with patch applied, desktopgrid windows don't jump around anymore.

Most of those effects didn't need special screen locking handling on
X11 as they prevented screen locking. On Wayland though, we don't
want the lock screen shown on a cube.

Eg. if a window is closed while "timeline.currentValue() == 0",
slotWindowClosed() will shortcut exit and not be removed from the
managers, thus dangle around forever.
Maybe there're other ways for a window to be deleted w/o
the closed slot being entered.

While the main plasma desktop containment does one
desktop per screen, that does not necessarily hold
for other containments, let alone other desktop shells
To indicate that the window is "active" ie. can
be dragged or activated (like in present windows)
There was either a bug or a forum post complaining
about the inability to activate windows from DG
They're only traversed and QHash is unordered - so
the worst container. Also we have complete control
over the maintained class, so we can just keep the
mapped EffectWindow there
before, hiding the buttons relied on the effect
seeing a paint event for the (with a low timeline
value) what's too wonky at least for instant animations
(certain failure) or when effect exits immediatey
(due to screen edge invocation issues or whatever)

Theory:
----------
because PresentWindowsEffect::screenCountChanged() is shortcut
for "if (!isActive())", but the desktopgrid doesn't call
PresentWindowsEffect::setActive (or at least
PresentWindowsEffect::screenCountChanged), so the effect can
"miss" the increasing screen count change (it sees the signal,
but ignores it) and when desktopgrid calls it, it assumes the
m_gridSizes array is big enough (but it isn't)
Steps:
----------
1. effects are loaded, 1 screen present
2. 2nd screen gets added, but inactive effects ignore that
3. desktop grid gets activated, updates according to screen count,
calls presentwindows for screen #2
4. presentwindows data is only prepared for one screen from step 1
=> BOOM

the (old) button effect windows used to be unreferenced
with the re-invocation of the effect. because we stopped
deleting/recreating the window, this approach failed and
the effect window was never deleted.
Unreferencing the window at proper occasion (see new hide
location) coked up - guess what - the exact same "texture is
junk" issue as for the QtQuick close button in present windows...
So we resort to the exact same stupid "hide by moving" solution
as we have there.

DesktopGrid uses PresentWindows Effect as a proxy effect. Instead of
hard coding the name of the Effect let's use the name resolving provided
by BuiltInEffects.
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.
Implemented in KWin core to forward to new global shortcut system. This
method should be extended/changed once we go to Qt5/KF5 to make the usage
easier (no more KAction).
Each global shortcut in the effects makes use of this new method.
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.
REVIEW: 115073
Most effects had a "collection" for one action. We don't need the
action collection, all it was used for is setting the object name.
With the removal of KActionCollection the effects do not need to link
XmlGui any more, though the dependency is still pulled in through
plasma.
