Summary:
The GL_CONTEXT_LOST flag is not reset when calling glGetError. This of
course bites with: "Thus, glGetError should always be called in a loop,
until it returns GL_NO_ERROR, if all error flags are to be reset."
(see https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glGetError.xhtml)
As KWin calls checkGLError from init call it can result in a freeze of
KWin. This is a regression reported multiple times since the release of
5.10.3 which enabled GLX_NV_robustness_video_memory_purge extension.
Please note that I am not able to test this change. I do not have an
NVIDIA card and are not hiting the problem. I have no way to simulate
the code. I do not know whether the change will fix the problem, it is
based on what others do. Inspiration for this change is mostly from

Summary:
We are getting reports about the shader self test failing in a false
positive way on Mesa 17. We already have such false positve results
for NVIDIA quadro and went with disabling the self test.
Most likely our self test has a problem or the rendering of the first
frame has a problem. But disabling compositing because our rendering of
the first frame is broken, is too much.
Let's better be pro user here and disable the shader self test till we
fixed the root problem.

This method already translates to s_virtualScreenGeometry as the source
co-ordinates are in compostior space we should take scaling into account here too.
This method already supports resizing if source and target sizes do not match.
Calling funcitons can either double the size of the target if they want native resolution
or leave as-is if they want the result in standard DPI.
This implements scaling in the screenshot, magnifier and simple blur effect.

Also it means that we don't have to hardcode the name kwinrc into the

use the define KWIN_CONFIG which gets generated based on the compile

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:
The feature has always been considered experimental. Unfortunately it is
completely unmaintained and hasn't seen any commits in years. It
requires kolor-manager to function, but that has not seen a release
based on frameworks yet. This makes it difficult to maintain. In fact I
have never been able from the introduction till now to setup a color
corrected system. One needs kolor-manager and oyranos and especially the
latter is hardly available on any linux distribution (e.g. not on the
Debian/Ubuntu systems).
Due to being unmaintained color correction in KWin did not keep up with
recent changes. Neither did it see any updates during the xlib->xcb
port, nor during the Wayland port. Especially the Wayland port with the
rendering changes make it unlikely to function correctly. E.g. Wayland
introduced a proper per-screen rendering, while color correction did a
"fake" per screen rendering. How that is going to work in combination is
something nobody ever tried. Now after the introduction of proper
per-screen rendering the solution would be to port color correction to
the new api, but that never happened.
Color correction also modified the shaders, but a newer shader API got
introduced some time ago. Whether the color correction shader support
that or not, is unknown to me. Also which shader language versions are
supported. I know it was based on 3d texture support, which back on
introduction was partially lacking in OpenGL ES. Nowadays that changed,
but color correction didn't update.
Last but not least it is completely X11 based and there is no work on
how to make it work with Wayland.
Given all the problems, especially the fact that it is unmaintained and
cannot be setup on my system, means to me that the only solution is to
remove it.
I'm open to having it reintroduced in future, but only if the
availability on Linux distributions gets addressed before. As long as
major linux distributions do not ship this feature, it should not be in
KWin. Given that I must say that it was a mistake to add it in the first
place and I need to point out that I was against the merge back then.

Summary:
Instead of having the egl extensions in the global kwinglutils lib it
becomes private to the AbstractEglBackend. Just like on glx the
glxextensions are moved into the platform.
The extensions are queried from initEglAPI, that is as early as possible
after initializing the EGLDisplay. This ensures that any implementing
subclass can access the extensions early enough.
As a note: the EglOnXBackend had a potentially wrong sequence for
initializing the buffer age extension. It is now moved to the correct
place where the result is needed for the first time.
From the global API eglExtensions are removed from hasGLExtension and
the eglExtensions function is dropped. As by that initEGL did not do
anything it is also dropped.

We are finally XLib free!
This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras. Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.
The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

Summary:
KWin still resolves some OpenGL function pointers. For that it needs to
use either eglGetProcAddress or glxGetProcAddress. With other words the
method to resolve needs to know whether it is egl or glx and needs both
a dependency to egl and glx. Especially the dependency to glx is ugly as
that pulls in XLib into our library.
The way so far was to pass an enum value to the initGL method to know
whether it's EGL or GLX. With this change the enum value is removed and
replaced by a function pointer to resolve the methods.
This simplifies the resolve code and allows to completely remove the glx
variant we still had in the library. Thus kwinglutils library is now glx
and XLib free.

Summary:
When windows get added some effects grab the window and want to be the
only one animating this window. For this the grab roles exists. An
effect being notified later on evaluates the grab state and does not
start the animation.
This process failed due to being dependent on the order the effects are
loaded. Window Added/Closed are signals emitted by EffectsHandler, thus
first come, first serve. The requested effect order does not play into
it.
Due to that it could happen that an Effect which should not animate,
started to animate as the grab was still there.
This change adds the possibility to be notified whenever the window data
changes. A new signal is added to EffectsHandler which is emitted
whenever the windowData changes. The interested effects connect to it
and cancel their (just started) animation for the window.
Adjusted effects are:
* ScaleIn
* Fade
* WobblyWindows
In case of WobblyWindows an additional logical error was fixed that the
animations were only run when an effect grabbed instead of the other way
around.

to Platform to provide such a PlatformCursorImage. By default it's the
cursor image the Platform tracks. On X11/standalone platform this new
virtual method is overriden and provides a PlatformCursorImage from X11
using the code previously used in screenshot effect.
Screenshot effect and zoom are adjusted to use the new API instead of

Summary:
On Wayland in multi-screen a "window" is used to render to per screen.
In OpenGL every "window" is at 0/0 and scissoring is in respect to the
window geometry. The rendering geometry passed to VBO rendering, which
performs the scissoring, is in virtual combined screen geometry space.
Thus the scissoring always removes any rendering on the second screen.
This results in e.g. wobbly windows not working on any additional screen
on Wayland.
This change makes the VBO rendering multi-screen aware by passing the
current virtual window geometry in each rendering pass. That replaces
the so far used virtual screen size. For single screen rendering or
multi-screen rendering on X11 this doesn't change anything as there is
always only one OpenGL window and the screen geoemetry starts at 0/0.
Thus the subtracting of x/y geometry do not affect the scissoring at
all.

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.
