8015e4e84e Add virtual method to Scene to get the EGL/GLX extensions
Summary:
We had a few places (e.g. DebugConsole, Platform) where the Scene was
cased into a SceneOpenGL to access the backend and get the extensions.

This change simplifies that by adding a virtual method to Scene directly
which is implemented in SceneOpenGL and returns the backend's
extensions.

Thus the casts to SceneOpenGL are no longer required.

Test Plan:
Opened debug console to verify extensions are listed,
triggered Outline to verify the sharing QPA context gets created.

9381411b91 Pass EGL information from AbstractEglBackend to Platform instead of query
Summary:
So far the Platform performed a deep query into the AbstractEglBackend
to get information such as EGLContext, EGLConfig, EGLSurface. This
change adjusts this so that the AbstractEGLPlatform forwards it directly
whenever it gets informed about one following the approach already used
for EGLDisplay. This simplifies the code a lot and allows to remove the
dependency on the actual scene backend from the Platform (in order to
split out the SceneOpenGL into a plugin).

Test Plan:
Run nested kwin_wayland, triggered Outline which requires all
those methods.

6168638cf4 Fix Platform::createDecorationRenderer
Was missing a return and due to that the decoration renderer never
got added to the Decoration.

Thanks to code coverage reports on build.kde.org! They showed me that
something must have went wrong with the commit series.

51561052ec Move screen inversion through XRandr into X11 standalone platform
Summary:
By moving the functionality into the Platform API we can also implement
support on other platforms which support this in general (e.g. DRM once
Roman's color adjustment patches landed).

a3dc2ad5a2 Move NonComposited Outline into the X11 standalone platform
Summary:
Creating the OutlineVisual is moved into the Platform API. The default
implementation creates the composited OutlineVisual. The X11 standalone
platform overrides it and creates the non composited outline in case no
compositing is used.

Test Plan:
Run kwin_x11 with KWIN_COMPOSE=N and KWIN_COMPOSE=X,
non composited outline and composited outline loaded

1cc38c929a Move updateXTime into the X11 standalone platform
Summary:
KWin::updateXTime only delegates into the platform API where the method
is a no-op. The actual implementation is moved into the X11 standalone
platform as it uses QX11Info which is non functional except on the X11
standalone platform.

This change exposes a problem with timestamp handling: on Wayland the
X11 timestamp does not get updated at all, causing e.g. window sync not
work correctly (c.f. bug 374881). We cannot implement the updating in the
same way as QX11Info/Qt xcb platform does it as that would introduce a
blocking roundtrip to XWayland which is dangerous.

As a side-effect this change removes linking to Qt5::X11Extras in kwin
core as it's no longer needed.

b4a79d30e6 Move the X11 specific OverlayWindow into the platform/x11
Summary:
The overlay window is only needed for the X11 based compositors. Given
that it is better suited in the X11 platform. Unfortunately it is not
possible to completely move it into the platform plugin as it is still
referenced in KWin core (e.g. SceneXRender). Due to that the
OverlayWindow in KWin core is turned into a pure virtual class with the
implementation being moved into the plugin.

The platform API gains a new virtual factory method which is only
implemented in the X11 platform.

Test Plan: Compiles

fd58c68ba5 Set wayland output scale
Summary:
Provides a virtual method in Screens where backends can supply the scale
of each screen, this is then set on each output.

For the X windowed backend this value is taken from a command line
parameter.

Test Plan:
Ran windowed mode with --scale 1 and 2
then kate --platform=wayland from another screen.
On the latter case UI elements were scaled up correctly

2904d4a0be Move X11 specific KGlobalAccel handling into the x11-standalone platform
Summary:
InputRedirection has a workaround to add a connect on a QAction which
is used for a global shortcut. This is specific to the X11 platform as
the xtime needs to be updated.

This change adds a new virtual method to the Platform and moves the
implementation into the X11 standalone platform. Thus it does no longer
gets called on Wayland.

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.

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

fd83366e31 Implement interactive window selection for Wayland platforms
Summary:
The interactive window selection is implemented in InputRedirection
through a dedicated InputEventFilter. The InputEventFilter so far takes
care of pointer input and keyboard input. In addition it ensures that
keyboard and pointer focus is reset on start and on end.

With this change KillWindow now also works on Wayland, but only for X11
windows, as the Wayland variant is not yet implemented.

7b464cf284 Support interactive window selection through the Platform
Summary:
A new virtual method is added to Platform:
startInteractiveWindowSelection

The interactive window selection enters a mode where the user can select
a window through the pointer or keyboard device. The cursor is turned
into a crosshair cursor, unless another cursor name is provided (e.g.
pirate for kill window).

Once a window is selected the provided callback method is invoked with
the selected Toplevel as argument. In case the user cancelled the
selection a nullptr argument is passed in.

Currently it's only implemented by the X11 standalone platform using the
logic from KillWindow. Just instead of killing the window the callback
is invoked.

KillWindow loses the X11 implementation and interacts with the new
functionality in Platform by providing a lambda function for the
killing.

Test Plan: Killing of X11 windows is still possible

e90e596864 Add way to hide/show cursor in Platform
Summary:
Some platforms support to hide and show the cursor. This will be needed
by e.g. the zoom effect which currently only provides this functionality
on X11.

This change introduces a new method in the Platform to hide and show the
cursor. The methods need to be called balanced and the implementation
takes care of only showing again if all hide got matched by a show.

The actual hiding and showing is performed in the platform plugins. So
far the DRM and X11/Standalone platforms implement the required
functionality, though other platforms probably could implement 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.

44843f462f [plugins/qpa] Support SharingPlatformContext on the existing eglSurface and eglconfig
Summary:
So far SharingPlatformContext was only used if the OpenGL context
supports EGL_KHR_surfaceless_context. If not supported, KWin tried to
create a context through the Wayland API. Unfortunately on hwcomposer
platform this results in a crash as libhybris only supports the init
of EGLDisplay for one native platform.

This change tries to also use the SharingPlatformContext if there is
an OpenGL context in general. It reuses the native EGLSurface created
for the compositing scene and makes its own OpenGL context current on
that surface, too. As KWin creates an FBO, it never renders to it, so
it shouldn't matter at all.

In order to prevent EGL_BAD_MATCH errors when making Qt's OpenGL context
current also the EGLConfig from the scene is used to create the context.

9d7ef58b2b Support restarting the OpenGL compositor on Wayland
Summary:
KWin needs to support restarting the OpenGL compositor in case of a
graphics reset event.

On Wayland the tricky part is that the applications should not notice
this. Most importantly KWin cannot just destroy the EGLDisplay and create
a new one. But this is how a restart works: the complete compositor gets
torn down and recreated - including the EGLDisplay.

This change moves ownership of the EGLDisplay to the Platform.
The AbstractEglBackend subclasses query the Platform whether there is
already an EGLDisplay. Only if there is no EGLDisplay the EGLDisplay is
created and only if no EGLDisplay is registered with Wayland the bind
is performed.

Another change is regarding the destruction: the AbstractEglDisplay does
no longer unbind the Wayland display and does no longer destroy the
EGLDisplay. The EGLDisplay is destroyed by the Platform - so very late
on application exit. The Wayland display is unbound when the Compositor
terminates.

Test Plan:
Limited testing with the added auto-test. This one needs to
be extended to fully verify that OpenGL applications continue to work.
But this requires build.kde.org to support OpenGL on Wayland.

736d99fc6a Properly trigger repaint for sofware cursor
Summary:
When the cursor changes the old and the new cursor geometry needs to
be repainted. Also when the cursor image changes a repaint of old and
new geometry is needed.

To support this the current cursor geometry is tracked instead of just
the cursor position. From the cursor position it's not possible to get
to the cursor geometry once the cursor image or hotspot changes, thus
the complete geometry needs tracking.

7c822fadee Move the OpenGL unsafe check into the Platform
Summary:
A new virtual method createOpenGLSafePoint is added to Platform.
This is invoked through the Compositor with a PreInit and a PostInit
argument pre and post creating the SceneOpenGL.

The Platform plugin can implement this and use it for detecting whether
creating the OpenGL compositor on this platform crashed in the past.
Thus it's the base for the openGLIsBroken platform check.

The x11 standalone plugin is the first to implement this functionality
using the previous code which was designed for X11.

This also means that a crash of the OpenGL compositor during init on
Wayland won't result in OpenGL being disabled.

d15d3a5ff1 Provide functionality of CompositingPrefs through Platform
Summary:
CompositingPrefs is only relevant for X11 standalone. It had some
"hacks" to make it not block Compositing on Wayland. Thus it was in
its current form not really useful.

Now all the functionality is provided through Platform with a default
implementation which is sensible for Wayland platforms.

The X11 standalone platform implements the new methods with the
Wayland checks removed.

In addition all calls to CompositingPrefs now go through the platform
directly and CompositingPrefs is completely dropped.

e73a86d420 Create screen edge through the Platform
Removes a diversion between X11 and Wayland. The base class Platform
creates an instance of class Edge with plugin implementations being
able to create a different type.

The X11StandalonePlugin does that and creates a WindowBasedEdge. For
this the implementation of WindowBasedEdge is moved from screenedges
into the plugin.

Unfortunately an ifdef is needed to make the screenedge test still
work as expected. This should be improved in future, e.g. have a good
way to load the platform plugin from the tests.
