75d39f6a8e Revert "wayland: Emulate tablet events only if there is pointer"
This reverts commit ee54fa7898.

Unfortunately, this is not a totally correct fix. If there's no pointer,
we need to announce the wl_pointer capability anyway so clients that do
not support tablet input devices can still receive emulated pointer
events.

58debd72a3 Only scanout when the texture matches the display size
Otherwise drmModeAtomicCommit() in DrmOutput::doAtomicCommit() fails due
to unmatched buffer sizes.

While rendering continues working properly, this makes drm freak out and
try to go back to a previous state (see the test commit in
presentAtomically()) that in turn starts issuing screen events to every
process even though it's just to say the same thing. The fact that this
happens per frame makes the system unusable as soon as fullscreen starts
happening on a scaled display.

Another thing we could do is get EglGbmBackend::scanout() to take care
of the resizing.

82551e143d Adapt to window management changes
Our wayland interface lifespan only needs to live as long as the window
is mapped.

Given this corresponds directly to the lifespan of AbstractClient we can
just set a parent and everything is handled implicitly.

c812ffbe1d Move basic activities support from X11Client to AbstractClient
We're now sharing most of the X11Client activity behavior accross all
clients. This allows to cleanup some of the existing virtuals and remove
quite a bit of code overalls.

Has to introduce an extra platform specific hook since X11Client
serializes the activity information in an atom and we will probably need
to do something similar on the Wayland platform at some point.

This allows us to start interacting with the activities with kwin
wayland. They are not restored properly accross sessions though since
nothing is really persisted and the session management still seems to
be amiss.

0eb37563e9 Restore script DBus API
The Script class has a DBus API we want to export. At some point this
has got broken and the run method is not exported.

It's a bit messy with script subclasses also having other invokables
that we want to export to scripts, so an adaptor is used to keep things
separated.

The interface name has technically changed, but KWin was doing something
weird and using the same interface names for the manager. Fortunately
calling Plasma code doesn't specify an interface so this still works.

1fb44b5bd5 effects/screenshot: Prepare for versioned dbus interface
On Wayland, when the compositor sends a screenshot to the requesting
app, it encodes the screenshot as a PNG image and sends the encoded data
over the pipe. The requesting app (Spectacle) then needs to decode the
data.

The issue is that encoding PNG images is not cheap. This is the main
reason why Spectacle is shown with a huge delay after you press the
PrtScr key.

In order to fix the latency issue, we need to transfer raw image data.
Unfortunately, the current dbus api of the screenshot is too cluttered
and the best option at the moment is to start with a clean slate.

This change prepares the screenshot effect for versioned dbus interface.
Most of existing dbus logic was moved out in a separate class. In order
to schedule screen shots, the screenshot effect got some new API.

    QFuture<QImage> scheduleScreenShot(window, flags)
    QFuture<QImage> scheduleScreenShot(area, flags)
    QFuture<QImage> scheduleScreenShot(screen, flags)

If a dbus interface needs to take a screenshot, it needs to call one of
the overloaded scheduleScreenShot() functions. Every overload returns a
QFuture object that can be used for querying the result.

This change also introduces "sink" and "source" objects in the dbus api
implementation to simplify handling of QFuture objects.

Note that the QFutureInterface is undocumented, so if you use it, you do
it on your own risk. However, since Qt 5.15 is frozen for non-commercial
use and some other Plasma projects already use QFutureInterface, this
is not a big concern. For what it's worth, in Qt 6, there's the QPromise
class, which is equivalent to the QFutureInterface class.

b3e7031893 platforms/drm: Fix potential stack corruption
If the file descriptor of the DRM device is greater than FD_SETSIZE, the
stack will be corrupted. However, it is highly unlikely that we ever hit
this case because DRM devices are opened at startup of kwin, so the file
descriptors should small.

In order to prevent the potential stack corruption, this change replaces
the usage of select() with poll().

Unlike select(), the api of poll() is much more sensible. Back 20 or so
years ago the main argument against poll() was that it's not implemented
by all platforms. But, nowadays, it's supported on all major platforms.

d9ec482257 x11: Initialize opacity when starting to track Unmanaged
This is a minor regression that was introduced with the refactoring of
Toplevel::opacity().

Previously, neither X11Client nor Unmanaged had to explicitly initialize
the opacity because it was queried from the net info object in
Toplevel::opacity().

With the refactored version, X11-specific opacity code was removed from
the Toplevel class. When starting to manage a window, the opacity must
be explicitly initialized.

ae6e6dc63c [scripting] Port ScriptedEffects to QJSEngine
Summary:
QScriptEngine is deprecated for years and suffers bitrot.
Plasma hit one super major bug with it in 5.11.0 and has now ported
away.

Main porting notes:
- creating low level functions no longer exists
The old global functions are exposed on the ScriptedEffect instance
and then the QJSValue wrappers of the globalObject are modified to
trampoline the methods at a wrapper level.

- We can then use QJSEngine to automatically do argument error checking
rather than unmarshalling a QJSValue manually which significantly
reduces a lot of code.

- We can't make FPX2 a native type, so these are QJSValue args and
unboxed there.

Long term I want overloads for animate that take int/QSize/QPoint which
are native JS types, but that might be an API break.

Test Plan:
Hopefully comprehensive unit test which passes
Tested fade/fadeDesktop manually.

It's a very invasive change, so I expect some things will be broke
please help test any JS effects.

33e3b92946 effects/wobblywindows: Allow model geometry and real geometry get out of sync
Currently, the wobbly windows effect assumes that the window data will
be updated on every repaint. However, there are legit cases when the
time diff between frames can be 0, for example when per screen rendering
is on.

If we are unlucky enough and the geometry of the window changes in that
very short moment, the mapping between window quads and the bezier
patch will be wrong. The window will most likely bounce back and forth.

In order to improve handling of that tricky case, this change makes the
computeBezierPoint() function take the "uv" coordinates rather than the
absolute "xy" coordinates of window vertices. This loosens the
connection between the real geometry of the window and the cached bezier
patch, and overall makes the effect's timing code more robust.

This can be also useful if the wobbly windows effect starts accumulating
time diffs and performing the integration step every N msecs with the
purpose of maintaining uniform "wobbliness" across different refresh rates.

e179fb697d platforms/drm: Refactor event dispatching code
There are a couple of reasons not to use the lambda:

* It is unnecessary. The DrmGpu has the DRM file descriptor
* If a crash occurs somewhere in the lambda, the backtrace will be hard
  to read
* Instead of processing events in the destructor of the DrmBackend
  class, we should keep dispatching events without involving
  QCoreApplication::processEvents() until all page flips are completed.

c6b638267a Fix crash on pasting too soon after copying from XWayland
There seems to be an interval between when you copy something from a Wayland
client and when you attempt to paste it into an X client where m_chunks.first().first
is empty, and trying to access its .data() will cause an assertion. While we can't
really gracefully handle this situation, we can at least terminate the function early
and turn the paste operation into a noop instead of a crash.

892b8cf6cb inputmethod: toggle the inputmethod if we get second show request
This is in a way working around bad protocol, input-method-unstable-v1
and also input-method-unstable-v2 does not have a way for input-method
to mark itself as "deactivated". This can happen when e.g. user closes
the virtual keyboard using swiping down or "close keyboard" button in
keyboard.

When this happens, the state between compositor, text_input and
input_method gets out of sync, compositor does not know that input
method got deactivated and hence it will continue sending various events
to it. The quick way around it is to change focus, which makes
compositor send deactivate request to input-method, that puts compositor
and input-method in sync again.

This patch aims to solve this by tracking the last state of input
method, If we know that input method is active and text input sends us
the show event, we toggle the input-method.

I will re-iterate that this is in no way proper solution, ideally
input-method-unstable-v3 or input-method-unstable-v2 even (since it is
not upstream anyway) gains the new request which essentially allows
input-method to sync enabled/disabled state with compositor.

This was making also the `needsSaving` signal fire only after

Use `onTextEdit()` instead, so the model is updated as the user

93e0265e4e Move source code to src/ directory
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.

This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.

We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
