Some hooks need to run on X11 startup.
On X11 this is handled by the login manager, for XWayland this is the
responsibility of the desktop.
Long term, we want Plasma to make XWayland actually on demand and therefore we
should use the initfd for these startup scripts before the application connects.

The alpha modifier protocol allows clients to set a multiplier for the opacity
of a surface, which allows them to offload some operations to KWin, which
in turn may offload them to KMS in the future
Makes it consistent with other KCMs and and Kirigami KCMs.
**Before:**
{width=431 height=399}{width=430 height=398}{width=431 height=399}
**After:**
{width=433 height=358}{width=436 height=361}
{width=443 height=367}

With this change, KXcursorTheme will be able to load svg cursors provided
by breeze.
If a cursor theme provides both xcursor cursors and svg cursors, the svg
cursors will be preferred.
At the moment, KXcursorTheme doesn't cache svg render results but it could
do that if it becomes a noticeable issue.
This effect is used to implement the visual bell accessibility feature.
It allows to implement it on Wayland and significantly improve it on X11,
where it's currently rather broken.
It offers two modes:
- Inverting the colors (code is based off the invert effect)
- Flashing a solid color
Some distributions do not wish to build the KWin X11 backend as
they do not use it, even though they wish to maintain X11 support
for Xwayland when using KWin as a Wayland compositor.
Allow this choice by splitting the build flag and setting it up to
forcibly disable building the backend when building X11 code is
switched off.
This is to prevent disconnecting clients that sometimes struggle with
keeping up with the events that the compositor sends. 1 MiB was eyeballed.
Wayland's wire protocol consists of a stream of messages. Every message
consists of a header (2 words: 1 word for object id, the other word
specifies the message size + event/request opcode) and the arguments.
Considering the compositor sending motion events generated by a mouse
with 1000Hz polling rate, we have
- wl_pointer.motion event size: (4 bytes for serial + 4 bytes for x +
4 bytes for y + 8 bytes for header) = 20 bytes
- wl_pointer.frame event size: 8 bytes for header
So in total, if the client freezes for a second, the client buffer size
should be at least (20 + 8) * 1000 / 1024 = 27 KiB. 1 MiB corresponds to
the client not processing the motion events for approximately 30 seconds.
Enabling this feature makes Xwayland send xtest events via
the remote desktop portal and libei.
XWayland will create a new session for each X client (it keeps
contexts around and reuses them if the cmdline matches, so not
every xdotool invocation produces a new portal prompt).
This adds a libeis backend via plugin which supports clients sending
emulated input events. No public listening socket is exposed,
clients are expected to go through the RemoteDesktop portal.
In order to restrict the device types available to clients
according to what was approved via the portal a separate eis
context per portal request is created. The communication with
the portal happens through a simple dbus interface where cookies
are handed out for each eis context so the portal can inform KWin
when the portal session is closed/should end.
Now that we have Wayland around, there's a whole branch of dependencies
that shouldn't be necessary anymore.
This allows to build KWin without all of it, allowing us to have a much
more compact alignment for cases where all the legacy software isn't
necessary anymore.
Bundle KWindowSystem X11-specific headers into it too, since it's part
of the same process.

Allows to notify systemd whether kwin is still running and possibly
restart the service if it stops responding.
Use Type=notify-reload to watch the kwin service. This will make it so
we receive SIGHUP rather than SIGTERM on the wrapper which we can handle
gracefully and stop the kwin process and restart as expected.
