Summary:
When a client sets a strut, checkWorkspacePosition will be called to
bump clients that touch corresponding screen edge.
In order to do that, checkWorkspacePosition needs to calculate client
boundaries before and after the restricted move area was changed. As it
turns out, if the client reserves space "between" screens, calculated
boundaries can be incorrect, which may lead to some funky results, e.g.
shrunken clients.
For example, let's say that there is a dual-monitor setup. If a client
reserves some amount of space at the right border of the left screen,
then clients on the right monitor will have rightMax which is equal to
the x coordinate of screenArea.
To fix that, this change ensures that only restricted areas belonging
to the same screen as the client are taken into account when computing
the boundaries.

Summary:
The size passed to an XDG shell configure request should match the
window size of the given window, we don't want to include the size of
any shadows that may be drawn by the client.
Kwin has the same concept of geometry for both window management, input
and rendering.
In order to approach this in a way that does not risk any regressions
with kwin's current structure AbstractClient::geometry remains the
canonical source and we handle the window within that internally within
ShellClient treating the windowGeometry as a set of margins from this.
This is part of a much bigger task (T10867). This patch addresses
windows growing when starting a drag based resize.

Summary:
This is used by GTK clients to know whether to draw as though they have
focus or not. Whilst it's most visible for CSDs headers, use of the
active/inactive palette (or backdrop class in GTK terms) applies
everywhere.
Rationale of the flag is to allow the WM to hint visual states without
giving input, i.e so you can hint that the parent of a modal dialog
should be shown as active. Though kwin only sets it on the truly active
window to match the behaviour our other windows follow.
BUG: 398832
I expect this to be potentially controversial as it's new code in X11,
so in advance:
* Unlike GTK_FRAME_EXTENTS, it is part of the specificiation (albeit
1.4) even i3 supports it.
* It does fix a real world issue
* It's only 2 lines (plus trivial boiler plate in kwindowsystem)
* It's in code path that we rely on for our existing code
* If there's a situation where this does break, the worst that will
happen is a client gets a visual hint to have focus incorrectly, which
ultimately is the same as the current state

Summary:
The compositor tries to switch to the next tabbox client when currently
highlighted client is closed. Though there is a small issue with that.
Because the switch happens too late, a dangling pointer can be inserted
into the unconstrained stacking order, which can lead to a crash later on.
There are two cases:
- compositing is on;
- compositing is off.
Compositing is on: TabBox will try to un-elevate currently highlighted
client, though by that time the client no longer owns EffectWindow, so
this is basically a no-op (that's why we haven't experienced this bug
before).
Compositing is off: TabBox will try to restack currently hightlighted
client under the next tabbox client. Given that the restack method
doesn't do any sanity checks(see Client::manage why), a client that is
about to be destroyed will be re-inserted back into the unconstrained
stacking order.
This change ensures that the switch happens before currently highlighted
client is removed from the stacking order.
BUG: 406784
Test Plan:
- Turn off compositing;
- Follow steps to reproduce in the bug report (see comment 2).

KWin replaces any non-printable character with a space. This check does not
handle surrogate pairs correctly. Additionally, translators sometimes insert
non-printable soft-hyphens into titles, which also cause KWin to display a
space instead.
This code adds the missing surrogate handling, and (to fix both issues), also
removes non-printable characters instead of replacing them with a space.
Also moved the changed test after these changes, so that changes in non-
printable characters do not cause unneeded redraws.
Unit tests adapted by Vlad Zagorodniy.

As a result, the calculated factor can be anywhere between 0 and 0.5

Summary:
Some old themes have the flag set and also a style which expects the
borders to be stretched. Given that the documentation on techbase
describes widgets/glowbar still as "a frame without a prefix", one also
would assume that all the optional hints (which make sense) still apply.
Even more, the Air & Oxygen themes have the hint also set, though for
their rendering it makes no difference.
The small code needed seems worth the unbreaking of old themes as well
as giving theme creators another variable of freedom for their styles.
Test Plan:
Glow bar still works on all corners and edges with all themes as before,
though rendering now as expected for themes which have the
"hint-stretch-borders" set.

CCBUG: 406101
Summary:
This is the initial implementation of a DRM backend based on the EGLDevice,
EGLOutput, and EGLStream extensions, supporting NVIDIA graphics hardware using
their proprietary driver. The new backend will be used if the environment
variable KWIN_DRM_USE_EGL_STREAMS is set. On initialization, it will attempt to
create an EGLDevice based on the DRM device currently in use and create
EGLOutputs and EGLStreams for any attached displays. These are used to control
presentation of the final composited frame. Additionally, it will register the
wl_eglstream_controller Wayland interface so that native EGL windows created by
clients can be attached to an EGLStream allowing buffer contents to be shared
with the compositor as a GL texture.
At this time there are two known bugs in the NVIDIA driver's EGL implementation
affecting desktop functionality. The first can result in tooltip windows drawn
by plasmashell to contain incorrect contents. The second prevents KWayland from
being able to query the format of EGLStream-backed buffers which interferes
with the blur effect. Fixes for both of these are currently in development and
should appear in an upcoming NVIDIA driver release.
Additionally, hardware cursors are currently not supported with this backend.
Enabling them causes the desktop to intermittently hang for several seconds.
This is also likely a bug in the NVIDIA DRM-KMS implementation but the root
cause is still under investigation.
Test Plan:
On a system with an NVIDIA graphics card running a recent release of their
proprietary driver
* Ensure the nvidia_drm kernel module is loaded with the option "modeset=1"
("# cat /sys/module/nvidia_drm/parameters/modeset" should print "Y")
* Ensure EGL external platform support is installed
https://github.com/NVIDIA/eglexternalplatform
* Ensure KWin was build with the CMake option
KWIN_BUILD_EGL_STREAM_BACKEND=ON (this is the default)
* Start a plasma wayland session with the environment variable
KWIN_DRM_USE_EGL_STREAMS set
* Ensure output from KWin OpenGL initialization indicates the NVIDIA EGL
driver is in use (as opposed to Mesa / llvmpipe).
* Desktop should be fully functional and perform smoothly.

Summary:
Since QPA only performs off-screen rendering, it does not require an EGLConfig
that supports any particular surface type. Currently it requests a config
supporting window surfaces, however the EGLDeviceEXT platform, which is the
basis of the EGLStream back-end used with the proprietary NVIDIA driver, does
not support such surfaces resulting in eglChooseConfig not returning any valid
configs when that back-end is in use. Since QPA doesn't actually create any
window surfaces, it should be fine to remove this restriction to allow it to
initialize properly with the EGLStream back-end.
