The brightness of the screen is read from the luminance tag, and through
the color management protocol(s) passed to apps, so that they can adjust
their content accordingly
If the client is slow, kwin can receive _NET_WM_MOVERESIZE requests
after user has released mouse buttons. Ideally, the window manager
should refuse starting an interactive move/resize operation in such a
case so it's still possible to finish moving or resizing the window
by releasing mouse buttons.
If somebody else claims the selection, it's unclear what we should do.
kwin can't give up its selection as it's the one who is responsible for
window management and compositing. If anything, Xwayland should ensure
that no client can claim WM_S0.
Apparently, libepoxy requires a current EGL display in order to resolve
EGL functions. This is unexpected as most of the EGL functions require no
current opengl context.
This change makes kwin bypass libepoxy for problematic cases.

Quick tile mode reset should be done in the interactive move handler,
where the new move offset is set. Only reset it on resize to unsnap
the window from the tile.

This addresses an issue where mpv window with keep aspect ratio enabled
cannot be fullscreened due to constrainClientSize() returning size that
doesn't fit full screen area.
NOTE: This has been tested with 3440x1440 display and 1920x1080 video in
mpv.
Strict geometry disables certain user activites; full screen requests
and only sending configure events at sizes the client claims to support.
This was added as a workaround for xterm in 19 years ago. It's a client
side bug as applications can still choose to ignore the configure event,
so kwin shouldn't have to sanitise them in advance. xterm seems to have
fixed it's bug, and pragmatically we know not all window managers
perform these checks so most clients should not be relying on it.
On Wayland this additional check is proving problematic, the handling of
scaling especially fractional scaling is hitting cases where it's better
to always ask the client to do what kwin wants.
Tests that refer to sizeIncrements are dropped as they are only used in
the strict geometry passes which is being obsoleted. Resizing in general
is still tested.
BUG: 481456
Previously a tile could intersect with the tile next to it when resizing tiles in tiles-editor.
This checks that the tile next to the resized one is not at minimum size already, and stops
resizing if it is.
Do note that any current setups that may get broken if there is tiles that intersect each other,
so they may have to remake the tile setup.

The perspective projection matrix has its y axis flipped vertically. It
should be undone when applying the render target transformation, otherwise
the rotation order will be wrong.
BUG: 481664
Try to send the tablet input to the configured screen for the tablet if any,
otherwise always send it to the active screen, not the screen of the active window
which is very confusing
BUG:479713
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.

The config may have HDR or WCG enabled, and the driver or display settings changed
since then to make it impossible to actually enable either.
The config values stay unchanged when this happens, so reconnecting the display with
HDR support will automatically turn it on again.
BUG: 481518
the behavior of converting negative floating-point numbers to unsigned
integers is undefined. It is necessary to keep the conversion behavior
consistent between ARM and x86 platforms.
through the above conversions, all become the two's complement of
negative numbers.

wl_surface size is not used when re-arranging surfaces. It also results in
excessive configure events.
Note that it can be useful for updating strut rects, but we could use the
next geometry, which is even preferrable over the frame geometry as the
Workspace would use proper struts earlier.
Otherwise, Qt thinks the old context is still current and will do things like
destroying VAOs with KWin's context, which ends up destroying the VAO of the
context and breaks rendering.
BUG: 479094
While the primary plane delivers a high enough refresh rate for the cursor to be
at least usable, delay cursor updates to be in sync with the primary plane. This
avoids stutter of the content being shown on the primary plane.
Because amdgpu doesn't handle this correctly at the moment, this feature is guarded
behind the KWIN_DRM_DELAY_VRR_CURSOR_UPDATES environment variable.
See https://gitlab.freedesktop.org/drm/amd/-/issues/2186 for more details on that.
In almost all cases it's duplicated in the name, and if the user manually
changes the name, the custom name should be shown without additional numbers
