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.

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

346619aa36 Remove KWin::display from kwinglobals
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.

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.

19147f5f85 [platformx/x11] Add a freeze protection against OpenGL
Summary:
With nouveau driver it can happen that KWin gets frozen when first trying
to render with OpenGL. This results in a freeze of the complete desktop
as the compositor is non functional.

Our OpenGL breakage detection is only able to detect crashes, but not
freezes. This change improves it by also added a freeze protection.

In the PreInit stage a thread is started with a QTimer of 15 sec. If the
timer fires, qFatal is triggered to terminate KWin. This can only happen
if the creation of the OpenGL compositor takes longer than said 15 sec.

In the PostInit stage the timer gets deleted and the thread stopeed
again.

Thus if a freeze is detected the OpenGL unsafe protection is written into
the config. KWin aborts and gets restarted by DrKonqui. The new KWin
instance will no longer try to activate the freezing OpenGL as the
protection is set.

If KWin doesn't freeze the protection is removed from the config as
we are used to.

Check for freezes for the first n frames, not just the first

This patch changes the freeze detection code to detect freezes in the
first 30 frames (by default, users can change that with the
KWIN_MAX_FRAMES_TESTED environment variable). This detects
successfully the freezes associated to nouveau drivers

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.

2a8ab547e1 Move X11Cursor into the x11standalone platform plugin
At the same time the xinput2 integration is split out of X11Cursor
and made a standalone part of the platform plugin. XInput integration
is nowadays not only used by the cursor position polling, but also
for modifier only shortcuts.

By splitting it out the modifier shortcuts start to work also when
one doesn't have anything requesting a mouse position polling.

This also simplifies the conditional builds: xinput integration is
only included if we have support for it at compile time without having
to have many ifdefs in the cursor implementation. For the inclusion of
cursor in the kcmkwin this also removes all the ifdefs.

The key events are only requested if we have xinput 2.1. Otherwise we
would not get all raw events if the input device gets grabbed.

03700500be Create Cursor instance through Platform
By default the InputRedirectionCursor is created and only the X11
standalone platform creates the X11 specific cursor.

This is a preparation step for moving the X11 specific cursor
implementation into the x11standalone platform plugin.

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.

48e69b77d9 If glx is not available try to create egl backend
Summary:
So far the OpenGL is unsafe check functionality in Compositor disabled
OpenGL compositing if glx is not available and we are in standalone X11
mode.

This is technically no longer correct for quite some time. Just because
GLX is not available doesn't mean that OpenGL doesn't work. We have an
EGL backend. So let's try to use that if glx is not available.

This change removes the check completely from Compositor. Instead the
standalone x11 plugin checks whether glx is available prior to createing
the glx backend. If not available it falls through to the egl backend.

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.

c45942a70c Move requiresCompositing from Application to Platform
Summary:
This change reduces the windowing system specific code pathes. Instead
of checking whether we are on X11 or Wayland to decide whether
compositing is required, we just ask the Platform.

The default is true, only x11 standalone allows to not require
compositing.

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.

Summary:
It's only needed by the standalone x11 variant. This allows us to

18939e17ed Move XRandrScreens to the x11/standalone plugin
By moving XRandrScreens the creation of screens gets simplified a lot
as there is no need to have windowing system specific init code. It all
just goes through the platform.

This also marks the point where the first X11 specific code is removed
from kwin_wayland.
