69b2c2fcea Set scale on glScissor calls
Summary:
glScissor works on window co-ordinates. i.e not scaled by the viewport
We need to multiply by the scale there.

This fixes a minor visual glitch in animations when using hardware
clipping.

Test Plan:
Hardcoded my minimise animation to be really slow.
Now every frame looks perfect

The FreeBSD build is currently failing with:

kwingltexture_p.h:83:23: error: no function named 'cleanupGL' with type
'void ()' was found in the specified scope
friend void KWin::cleanupGL();

This change hopefully addresses the problem.

8ae37c420b Move SceneOpenGL into a dedicated plugin
Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite

Test Plan: Nested OpenGL compositor works

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

20e22ec26a Deprecate global KWin::displayWidth and KWin::displayHeight
Actually they could go directly as nothing in KWin uses them anymore.
But there are more functions in kwinglobal which need to go as they
don't support restarting XWayland. So instead of breaking internal ABI
several times, just deprecate till everything is prepared.

aefb5f4dd9 Prevent endless loop in checkGLError due to GL_CONTEXT_LOST
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

43816119e9 Skip Shader self test for Mesa >= 17
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.

BUG: 376801
FIXED-IN: 5.10.4

Test Plan: It compiles.

71600d0a02 Take into account scaling in blitFromFrameBuffer
Summary:
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.

Test Plan:
Tested screenshot effect using spectacle.
I hit an (unrelated, was reproducible on master) crash whilst using this, so it is not fully tested

Ran magnifier effect manually

Summary:
There are a few places where KWin needs to read values from kcminputrc.
As I need to add yet another one it makes more sense to properly
structure it like in other cases and have only one kcminputrc hold in

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.

ebebc6ca82 Provide scale offset to WindowVertex calculation
Summary:
WindowVertex contains the x position and also the relative texture x position

Our textures are scaled bigger than kwin's resolution, so this makes sure we set the right
texture position.

Otherwise our final array ends up using 0 to 0.5 of the texture, not 0 to 1.

Opened some 2x windows, on a 1x output.
It looked how it should do, instead of it being double the size and cropped

22c91df2ec Add support for global touchpad swipe gestures
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.

f9f7b84cb4 Add interactive position selection to screenshot screen under cursor
Summary:
A second interactive selection mode gets added to select a position on
the screen. This is handled by the same input event filter as for the
window selection. Just that instead of returning a window, it returns a
QPoint.

This allows to pick a point on the screen which we need to screenshot
the screen under the mouse cursor and in future for color picking.

The screenshot effect provides two new dbus methods to (interactively)
select a screen or fullscreen. This allows spectacle to screenshot the
(full) screen with still having the user in control.

17e0bad922 Drop OpenGL based color correction from KWin
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.

d1de6899fd Move querying the egl extensions into the AbstractEglBackend
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.

Test Plan:
Tested nested kwin on Wayland, still works, extensions shown
in debug console

Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
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.

d7fa827644 Pass function ptr to resolve glFunctions to initGL
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.

Test Plan: nested KWin with OpenGL/EGL still works

730fd05f58 Move querying glx extensions into the platform plugin
Summary:
Glx extensions are only interesting to the glxbackend. Given that
querying can be moved there.

In order to simplify the extensions can be stored in the OpenGLBackend
which also provides the convenience check as before.

The egl platforms should also be adjusted to query in that way and
remove it from the kwinglutils.

There is still a usage of the glxextensions inside kwinglutils to
resolve one function. That should also be moved into the platform.

fb69b791a1 Ensure that all Effects honour the grab roles correctly
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.

bedc01b108 [kwineffects] Add hide/show cursor to EffectsHandler
Summary:
The implementation delegates to the Platform to perform the actual
show/hide of the cursor image.

This replaces the implementation in the zoom effect which so far
directly interacted with xfixes to show/hide the cursor. This is now
provided by the x11/standalone platform. And due to this change the zoom
effect can now properly hide the cursor on platform DRM (wayland) as
well.

ea52ef9e57 Add a PlatformCursorImage to Platform and EffectsHandler
Summary:
There are several effects (screenshot, zoom) which need access to the
cursor image and cursor hotspot. So far these effects used X11
unconditionally to get the cursor which obviously does not work on
Wayland.

This change adds a new class PlatformCursorImage to kwinglobals which
wraps what a cursor is (image and hotspot) and adds a new virtual method
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
X11.

Test Plan:
Zoom effect tested on Wayland, now gets the proper cursor icon.
X11 functionality not yet tested.

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.

ff6e042c7f Fix scissoring of VBO rendering in multi-screen setup on Wayland
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.

2545162f87 Support highlighting windows through EffectsHandlerImpl
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.

6af0cc6ebe Add support for touch events in the Effect system
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.

142aab2e24 Introduce an EffectsHandler::animationsSupported -> bool
Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.

This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.

As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.

The information whether animations are supported comes from the Scene.
It's implemented in the following way:
 * XRender: animations are always supported
 * QPainter: animations are never supported
 * OpenGL: animations are supported, except for software emulation

In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.

a9f450db27 Allow to create an OpenGL Compositor with llvmpipe
Summary:
This is a radical change to the approach KWin used to have. So far KWin
fall back to XRender compositing if it detected llvmpipe. With this
change KWin will use OpenGL compositing also on llvmpipe.

This has drawbacks: it's CPU emulated which we actually do not want.
But the question is whether it still makes sense to keep the no-GL
enforcement.

There are several things to consider here:
* QtQuick will use llvmpipe anyway (including things like Plasmashell)
* glamor might be used in the xorg layer which also uses llvmpipe on
  XRender
* more consistent look
* we get OpenGL working in tests (important for e.g. openQA)
* hardware which does not support proper GL gets less, there are
  GL drivers for KVM, there are GL drivers for rPI, etc. We don't
  need to block it anymore because of possibly bad results on those
  hardware. Also they mostly use glamor.
* there is still the way to manually select XRender/QPainter compositing

d49fba5d30 [libkwinxrenderutils] Clean up static blend picture before going down
Summary:
The method xRenderBlendPicture created a static XRenderPicture on
first usage. To cleanup a XRenderPicture an xcb_connection_t* is needed.
As it's static the cleanup happens on exit handler and at that time Qt
already destroyed the xcb_connection_t*. With a certain chance this will
crash.

To expose the problem a Q_ASSERT(qApp) is added in the destructor of
XRenderPicture. Using xrenderBlendPicture() will hit this assert on
application exit. This is demonstrated by the added auto test.

The actual fix to the problem is moving the static variable out of
the method and introduce a global cleanup method just like the init
method. This is now called from Workspace dtor, so before application
goes down.

Summary:
Client uses a static Xcb::Window helper. This so far didn't get
explicitly destroyed, so the application finalize cleaned it up.
To destroy the window the xcb_connection_t* is used which the
QGuiApplication already destroyed.

This change ensures that the window gets destroyed before the xcb
connection gets destroyed.

In addition an assert is added to KWin::connection() to ensure that
we still have the QGuiApplication::instance() when it's invoked.
This way we'll notice if we have more cases where we call into xcb
after the application went down.

54870d5e14 [libkwinglutils] Cleanup Shader API: removal of ShaderType
As all effects are ported to the ShaderTraits API the old ShaderType
API can be completely removed.

ef7f7b0179 [kwinglutils] Don't setup old shader API for rendering a texture
Old shader API no longer in use, so we don't need to setup the texture
rendering.

4b11b7b6b8 [kwineffects] Add a generateCustomShader to ShaderManager
This method allows to generate a shader with ShaderTraits but one
part (e.g. vertex and/or fragment) to be replaced by custom shader
code.

Thus it can be used as a replacement for the load*(ShaderType) variants
and allows more effects to transition to shaders using traits.

3be6ff9f12 [kwineffects] Pass screen projection matrix to WindowPaintData
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.

f284ef814c Pass projection matrix to ScreenPaintData
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.

bcc36b87fb Avoid undefined behavior in nearestPowerOfTwo.
The way nearestPowerOfTwo is currently defined allows for the possibility of
left-shifting an int by 32 bits or more, which is undefined behavior on
platforms where int is 32 bits, and is something that can happen here if `s`
is equal to 31 by the end of the loop. Noted by Coverity as CID 1291191.

This patch takes an algorithm to perform the same operation from Hank Warren
Jr.'s book "Hacker's Delight", which should avoid UB.
