[libkwineffects] Introduce API to easily show a QtQuick scene in an effect Summary: EffectQuickView/Scene is a convenient class to render a QtQuick scenegraph into an effect. Current methods (such as present windows) involve creating an underlying platform window which is expensive, causes a headache to filter out again in the rest of the code, and only works as an overlay. The new class exposes things more natively to an effect where we don't mess with real windows, we can perform the painting anywhere in the view and we don't have issues with hiding/closing. QtQuick has both software and hardware accelerated modes, and kwin also has 3 render backends. Every combination is supported. * When used in OpenGL mode for both, we render into an FBO export the texture ID then it's up to the effect to render that into a scene. * When using software QtQuick rendering we blit into an image, upload that into a KWinGLTexture which serves as an abstraction layer and render that into the scene. * When using GL for QtQuick and XRender/QPainter in kwin everything is rendered into the internal FBO, blit and exported as an image. * When using software rendering for both an image gets passed directly. Mouse and keyboard events can be forwarded, only if the effect intercepts them. The class is meant to be generic enough that we can remove all the QtQuick code from Aurorae. The intention is also to replace EffectFrameImpl using this backend and we can kill all of the EffectFrame code throughout the scenes. The close button in present windows will also be ported to this, simplifiying that code base. Classes that handle the rendering and handling QML are intentionally split so that in the future we can have a declarative effects API create overlays from within the same context. Similar to how one can instantiate windows from a typical QML scene. Notes: I don't like how I pass the kwin GL context from the backends into the effect, but I need something that works with the library separation. It also currently has wayland problem if I create a QOpenGLContext before the QPA is set up with a scene - but I don't have anything better? I know for the EffectFrame we need an API to push things through the effects stack to handle blur/invert etc. Will deal with that when we port the EffectFrame.

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.

Add windowsystem plugin for KWin's qpa Summary: KWindowSystem provides a plugin interface to have platform specific implementations. So far KWin relied on the implementation in KWayland-integration repository. This is something I find unsuited, for the following reasons: * any test in KWin for functionality set through the plugin would fail * it's not clear what's going on where * in worst case some code could deadlock * KWin shouldn't use KWindowSystem and only a small subset is allowed to be used The last point needs some further explanation. KWin internally does not and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is exposing information which KWin sets. It's more than weird if KWin asks KWindowSystem for the state of a window it set itself. On X11 it's just slow, on Wayland it can result in roundtrips to KWin itself which is dangerous. But due to using Plasma components we have a few areas where we use KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in direction, blur and background contrast. This we want to support and need to support. Other API elements we do not want, like for examples the available windows. KWin internal windows either have direct access to KWin or a scripting interface exposed providing (limited) access - there is just no need to have this in KWindowSystem. To make it more clear what KWin supports as API of KWindowSystem for internal windows this change implements a stripped down version of the kwayland-integration plugin. The main difference is that it does not use KWayland at all, but a QWindow internal side channel. To support this EffectWindow provides an accessor for internalWindow and the three already mentioned effects are adjusted to read from the internal QWindow and it's dynamic properties. This change is a first step for a further refactoring. I plan to split the internal window out of ShellClient into a dedicated class. I think there are nowadays too many special cases. If it moves out there is the question whether we really want to use Wayland for the internal windows or whether this is just historic ballast (after all we used to use qwayland for that in the beginning). As the change could introduce regressions I'm targetting 5.16. Test Plan: new test case for window type, manual testing using Alt+Tab for the effects integration. Sliding popups, blur and contrast worked fine. Reviewers: #kwin Subscribers: kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D18228

Better handling for making the compositing OpenGL context current With QtQuick2 it's possible that the scene graph rendering context either lives in an own thread or uses the main GUI thread. In the latter case it's the same thread as our compositing OpenGL context lives in. This means our basic assumption that between two rendering passes the context stays current does not hold. The code already ensured that before we start a rendering pass the context is made current, but there are many more possible cases. If we use OpenGL in areas not triggered by the rendering loop but in response to other events the context needs to be made current. This includes the loading and unloading of effects (some effects use OpenGL in the static effect check, in the ctor and dtor), background loading of texture data, lazy loading after first usage invoked by shortcut, etc. etc. To properly handle these cases new methods are added to EffectsHandler to make the compositing OpenGL context current. These calls delegate down into the scene. On non-OpenGL scenes they are noop, but on OpenGL they go into the backend and make the context current. In addition they ensure that Qt doesn't think that it's QOpenGLContext is current by calling doneCurrent() on the QOpenGLContext::currentContext(). This unfortunately causes an additional call to makeCurrent with a null context, but there is no other way to tell Qt - it doesn't notice when a different context is made current with low level API calls. In the multi-threaded architecture this doesn't matter as ::currentContext() returns null. A short evaluation showed that a transition to QOpenGLContext doesn't seem feasible. Qt only supports either GLX or EGL while KWin supports both and when entering the transition phase for Wayland, it would become extremely tricky if our native platform is X11, but we want a Wayland EGL context. A future solution might be to have a "KWin-QPA plugin" which uses either xcb or Wayland and hides everything from Qt. The API documentation is extended to describe when the effects-framework ensures that an OpenGL context is current. The effects are changed to make the context current in cases where it's not guaranteed. This has been done by looking for creation or deletion of GLTextures and Shaders. If there are other OpenGL usages outside the rendering loop, ctor/dtor this needs to be changed, too.

[libkwineffects] Introduce API to easily show a QtQuick scene in an effect Summary: EffectQuickView/Scene is a convenient class to render a QtQuick scenegraph into an effect. Current methods (such as present windows) involve creating an underlying platform window which is expensive, causes a headache to filter out again in the rest of the code, and only works as an overlay. The new class exposes things more natively to an effect where we don't mess with real windows, we can perform the painting anywhere in the view and we don't have issues with hiding/closing. QtQuick has both software and hardware accelerated modes, and kwin also has 3 render backends. Every combination is supported. * When used in OpenGL mode for both, we render into an FBO export the texture ID then it's up to the effect to render that into a scene. * When using software QtQuick rendering we blit into an image, upload that into a KWinGLTexture which serves as an abstraction layer and render that into the scene. * When using GL for QtQuick and XRender/QPainter in kwin everything is rendered into the internal FBO, blit and exported as an image. * When using software rendering for both an image gets passed directly. Mouse and keyboard events can be forwarded, only if the effect intercepts them. The class is meant to be generic enough that we can remove all the QtQuick code from Aurorae. The intention is also to replace EffectFrameImpl using this backend and we can kill all of the EffectFrame code throughout the scenes. The close button in present windows will also be ported to this, simplifiying that code base. Classes that handle the rendering and handling QML are intentionally split so that in the future we can have a declarative effects API create overlays from within the same context. Similar to how one can instantiate windows from a typical QML scene. Notes: I don't like how I pass the kwin GL context from the backends into the effect, but I need something that works with the library separation. It also currently has wayland problem if I create a QOpenGLContext before the QPA is set up with a scene - but I don't have anything better? I know for the EffectFrame we need an API to push things through the effects stack to handle blur/invert etc. Will deal with that when we port the EffectFrame.

Add windowsystem plugin for KWin's qpa Summary: KWindowSystem provides a plugin interface to have platform specific implementations. So far KWin relied on the implementation in KWayland-integration repository. This is something I find unsuited, for the following reasons: * any test in KWin for functionality set through the plugin would fail * it's not clear what's going on where * in worst case some code could deadlock * KWin shouldn't use KWindowSystem and only a small subset is allowed to be used The last point needs some further explanation. KWin internally does not and cannot use KWindowSystem. KWindowSystem (especially KWindowInfo) is exposing information which KWin sets. It's more than weird if KWin asks KWindowSystem for the state of a window it set itself. On X11 it's just slow, on Wayland it can result in roundtrips to KWin itself which is dangerous. But due to using Plasma components we have a few areas where we use KWindowSystem. E.g. a Plasma::Dialog sets a window type, the slide in direction, blur and background contrast. This we want to support and need to support. Other API elements we do not want, like for examples the available windows. KWin internal windows either have direct access to KWin or a scripting interface exposed providing (limited) access - there is just no need to have this in KWindowSystem. To make it more clear what KWin supports as API of KWindowSystem for internal windows this change implements a stripped down version of the kwayland-integration plugin. The main difference is that it does not use KWayland at all, but a QWindow internal side channel. To support this EffectWindow provides an accessor for internalWindow and the three already mentioned effects are adjusted to read from the internal QWindow and it's dynamic properties. This change is a first step for a further refactoring. I plan to split the internal window out of ShellClient into a dedicated class. I think there are nowadays too many special cases. If it moves out there is the question whether we really want to use Wayland for the internal windows or whether this is just historic ballast (after all we used to use qwayland for that in the beginning). As the change could introduce regressions I'm targetting 5.16. Test Plan: new test case for window type, manual testing using Alt+Tab for the effects integration. Sliding popups, blur and contrast worked fine. Reviewers: #kwin Subscribers: kwin Tags: #kwin Differential Revision: https://phabricator.kde.org/D18228
