InputDeviceHandler keeps track of which client has focus, and whether
the decoration or main window has focus.
Should the decoration get destroyed whilst the decoration has focus we
don't update correctly. This can happen when
"BorderlessMaximizedWindows" is set, or if you use key presses whilst
above the decoration.
cleanupDecoration (which is an odd name) is called whenever a decoration
gains or loses focus. Here we can connect for the decoration destruction
and force a focus change.

The screen count can be retrieved by checking the number of items in the
EffectHandler.screens property.
The replacement for the numberScreensChanged signal are the screenAdded
and the screenRemoved signals.
The main motivation behind this change is to clean up the screens api
and reduce the number of usages of the Screens class.
This provides a way to create, destroy, and rename virtual desktops in
the overview effect as well as switch between desktops.
The mechanics of switching between virtual desktops can be revisited
later though.
This can be useful for QML scripts that deal with virtual desktops.
The virtual desktop model keeps a copy of virtual desktop objects to
avoid hitting asserts in QAbstractItemModel (it has some asserts to
ensure that indices passed to beginInsertRows() or beginRemoveRows()
make sense).
When we're adding the output to the EglGbmBackend pipelines aren't necessarily
setup yet and are thus missing the modifier list. As creating the gbm surface
immediately is useless anyways, delay that until we need it, where the modifier
list is available.
First we check to see if the color scheme has header colors, and if it
doesn't, we turn around and ask for them anyway, relying on implicit
behavior in kcolorscheme that falls back to Window colors when Header
colors are requested but are not present. Instead, let's just ask for
Window colors to avoid the run-around and stop relying on implicit
behavior.
Currently, idle timers are not restarted on user input which triggers
the lockscreen even though the user is active at computer.
This change fixes that by making sure that idle timers are restarted
whenever SeatInterface's timestamp changes, i.e. user moves the pointer
or presses a key, etc.
Linking builtin effects against KCMs is really awkward. This change
decouples builtin effects from KCMs that use EffectsModel.
In order to discover builtin effects, metadata files are installed in
kwin's data dir, which will be subsequently read by EffectsModel.
The main motivation behind this change is to prepare kwin for importing
kwayland-server code in libkwin.
As is, builtin effects are linked with libkwin. Some builtin effects
have wayland specific code. If we move wayland stuff in libkwin, there's
going to be a circular dependency between kwin4_effect_builtins and
libkwin targets.
This change intends to break that dependency by linking builtin effects
to kwin executable.
The main issue with that is that EffectLoader would need to discover the
effects indirectly. QStaticPlugin is used for that purpose.
Besides breaking the cyclic dependency, it makes builtin effects use the
same plugin infrastructure in libkwineffects that external effects use.
Metadata in src/effects/effect_builtins.cpp was converted in a list of
python dictionaries, which was fed to a python script that generated
main.cpp and metadata.json files.
As is, libkwineffects doesn't use any specific apis in kwayland-server,
it simply "forwards" wayland display and surfaces from libkwin. Given
that, there is no need to link libkwineffects with kwayland-server. If
an effect needs to access wayland specific stuff, it can link explicitly
against kwayland-server.
The main motivation behind this change is to further loosen up
dependencies between various kwin components and kwayland-server so the
latter can be moved back to kwin.
Before attempting to create scenes, kwin will redirect windows but if
the opengl scene can't be created, it won't unredirect windows, which
seems to cause issues on aarch64.
BUG: 443953
API-wise it's odd to require absolute position with relative pointer
moves.
This cleans up some of InputRedirection code by making it simply forward
pointer input events from input devices to the pointer input device
handler, which knows better what to do with the delta value.
The pointer input device handler will compute the absolute position based
on the specified delta value, but it could also do something else, e.g.
not move the pointer at all if it's locked, etc.
