This allows KWin to securely identify the client for a given connection,
without relying on the process name.
This patch does not do anything meaningful with the application ID other
than store it.
This first version does not support kwin restarts, it can come
afterwards.
Testing done:
With latest flatpak, running `WAYLAND_DEBUG=1 flatpak run org.telegram.desktop |& grep security`
shows that flatpak itself bound the security context, and the client did not see it advertised.
It doesn't make sense for a window to become 1x1 pixels small. When we have
server side decorations we also know that the decoration takes a lot of
space, so this commit enforces a bigger minimum size for decorated windows
BUG: 469237
Window::acceptsFocus() is not taken into account when a window is
activated using Workspace::activateWindow(). The main reason is because
of different input models on X11.
Instead, Window::takeFocus() should check itself if the window accepts
focus.
This makes the api of EffectWindow more similar to the api of Window. It
also makes more sense to keep such signals in EffectWindow. In the future,
the effect window can be dropped in favor of the window.
Instead of an external service (like KScreen) storing and restoring output configurations,
with this commit KWin takes over that responsibility. This allows it to, among other things,
generate appropriate configs for new sets of outputs immediately, and take KWin-internal information
about outputs into account when generating them.

At the moment, the wayland compositor has to handle the case of having
no workspace. This should be unnecessary and it creates a pesky cycling
dependency between Workspace and Compositor.
Given that the Workspace acts more like a container and kwin starts
accepting client connections after starting compositing, it's possible
to create the Workspace earlier and simplify the start() function a bit.
There's "major" and "minor" defines that can get implicitly included, for
example with musl libc. To prevent that from breaking compilation, rename
the methods
In many cases it's irrelevant, what we care about is whether given effect
is loaded and performs its function. So remove these paranoid checks
except the tests where it's important to use OpenGL compositing.
Ensures that e.g. context menus move about with their parents when they
get moved around.
However, as per spec don't re-constrain the window when its positioner
is non-reactive. This change calculates the offset from its parent window
once initially and places the window relative to that whenever the parent
moves.
Only when the positioner is reactive, will it recalculate the placement fully.
BUG: 461994
`Placements::placeSmart` searches for an optimal position for windows, attempting to minimize overlap. The core of this algorithm tracks the
client's height and width in `ch` and `cw`, which have been adjusted by -1. This simplifies logic determining the bottom and right points of a
window when you are starting at the top and left points.
However, this decision requires adjusting that number by +1 when doing the opposite: determining the top and left points when you start with
the bottom and right points.
placeSmart cycles through window locations, searching for acceptable nooks and crannies to fit a window in, nicely. It begins by checking
for places to put the top left corner of the window which abut another constraint. If that fails, it then tries to place the bottom right
abutting a constraining feature.
After finding a suitable bottom (or right) location, the top (or left) location must be determined, requiring the -1 adjustment to be undone.
This patch adds that +1 back in.
# The bug it solves
This error can be seen by opening a bunch of windows that are placed using the "Minimal Overlapping" rule. The open space on the screen will be tiled from left to right, and then top to bottom in the windows. Once no more windows can be placed like that, the next window will be placed at the extreme bottom-right corner. However, it will be one pixel too low and one pixel too far to the right---if you try to move the window, it will "snap" to the correct spot.
This single pixel may seem minor or even irrelevant, but when you use the "Present Windows" desktop effect on a multiple-monitor setup, this one pixel will cause the window to show up on both monitors.
* speeds up incremental builds as changes to a header will not always
need the full mocs_compilation.cpp for all the target's headers rebuild,
while having a moc file sourced into a source file only adds minor
extra costs, due to small own code and the used headers usually
already covered by the source file, being for the same class/struct
* seems to not slow down clean builds, due to empty mocs_compilation.cpp
resulting in those quickly processed, while the minor extra cost of the
sourced moc files does not outweigh that in summary.
Measured times actually improved by some percent points.
(ideally CMake would just skip empty mocs_compilation.cpp & its object
file one day)
* enables compiler to see all methods of a class in same compilation unit
to do some sanity checks
* potentially more inlining in general, due to more in the compilation unit
* allows to keep using more forward declarations in the header, as with the
moc code being sourced into the cpp file there definitions can be ensured
and often are already for the needs of the normal class methods
There are use cases for the headers to be used, e.g. when implementing
wayland-specific workflows from an Effect.
In order to be able to use these, we also need to expose libkwin to be
imported as it carries the interfaces' symbols.

Static plugins being linked with shared libraries doesn't work smoothly.
POSITION_INDEPENDENT_CODE target property needs to be set for
every such plugin. However, there can be targets that we have no control
over, which need POSITION_INDEPENDENT_CODE to be set too. Asking such
projects to add this property and them refusing to do so would be
reasonable because kwin's entire static plugin pipeline is weird.
The test framework was made a shared library because kwin build
directory used to get really big (in 10s of gigabytes).
Due to the -fPIC issues, this change makes the test framework a static
lib again. Obviously, this brings back the big build directory problem.
But, it's not as terrible as it used to be. With this change, kwin build
directory is a couple of gigabytes in debug build, which is a lot but
not as bad as it used to be before.
The InputConfig was introduced to handle tests that don't have valid
kwinApp object. Those tests have been either reworked or dropped, so
let's drop the InputConfig to tidy the config stuff.
Interactions with KScreen cause settings to be reset to the default when the lid
gets closed, so handling lid closing in KWin needs to wait until KScreen no longer
writes configs
