Set the implicit size of the item to the client frameGeometry size.
This is also more convenient for tabbox usage than accessing it through the
client's property, had a proper notify signal and abstracts it from the
implementation.
It also can be mimicked by the preview ThumbnailItem used in the tabbox KCM,
which has no client property.
The TabBox preview uses a mock WindowThumbnailItem mimicking the
real item, but it was missing the `sourceSize` property, preventing
some effects to be previewed if they use it.
Since binary effects are installed in their own directory, checking
service type is redundant. Also, KPluginMetaData::serviceTypes() has
been deprecated.

The current "Minimize Overlapping" window placement tends to position
windows in locations that seem completely random, typically in a screen
corner. It is doing this because, true to its name, it is trying to
avoid overlapping other windows as much as possible. However in practice
this is rarely helpful. When the user opens a new window, it's because
they want to use it, and positioning the window far from where the
user is likely to be looking is counter-productive. This is even more
true on today's large and wide displays, where placing the window in a
corner may position it entirely outside the user's current field of
vision. We get bug reports about this exact issue for notifications
(which always appear in a corner by default) by users of such screens.
For notifications, this can be justifiable because notifications are
designed to be ignorable; app windows on the other hand, are not.
As a result, I commonly see Plasma users open windows and then
immediately, reflexively grab the window's titlebar and drag it to the
center of the screen. I have seen my wife do this. I have seen every
YouTube reviewer of Plasma do this. I have even see fellow KDE
developers at sprints do this. It seems like quite a common impulse
to want a newly-opened window to appear in the center of the screen,
which is where the user is likely to already be looking.
Thankfully, KWin already has a window placement mode that does this
automatically: "Centered". Accordingly, this commit changes the default
KWin window placement mode from "Minimize Overlapping" to "Centered".
No kconf migration script is provided because this is a better default
for most people in most cases, and existing users are highly likely to
appreciate this change.
This improves file organization in kwin by putting backends in a single
directory.
It also makes easier to discover kwin's low level components for new
contributors because the plugins directory may come as the last place to
look for. When one hears "plugin", the first thing that comes to mind is
regular plugins, not low level backends.
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.
This change merges the two OpenGL backends into one making the current
default of GLCore the overall default. It becomes the first context to
try to create. If it fails, it will automatically fall back to the
(previous) OpenGL 2 backend.
Reasoning: the differentiation of OpenGL 2 and 3 is a very technical one
and hard to understand for users. It is not obvious which one is better
or should be used. This results in many user discussions like "Which
backend to use?"
Back when the OpenGL 3 backend was introduced the dedicated feature made
sense. It was a new code base using new driver features. Nowadays the
code base in KWin is robust and mature and so are the drivers. A driver
advertising support for OpenGL 3 will support OpenGL 3. We don't have to
plan for driver breakage in this area any more.
Also our code evolved through the context attribute builder which gives
us the possibility to more easily fall back in case we cannot create the
context. Thus the need to select the backend is not so important as it
used to be when the feature got introduced.
If a user still wants to force OpenGL2, it is still possible by setting
the appropriate environment variables like MESA_GL_VERSION_OVERRIDE.
This change brings the improvement that the backend selection is now
completely removed from the compositing KCM.
If the virtual desktops rule is created, only the last virtual desktop
the window is on is going to be checked.
With this, all virtual desktops that the window is currently on will be
checked.
Technically, it's an api breaking change, but the window rules kcm is
the primary user of queryWindowInfo() so I don't think it's a big deal.
KPluginMetaData::findPlugins only returns valid json metdata, the previous
check was accidentally kept for the condition that the plugin provides a theme engine.

Port the RuleSettings and KCM to store and use a list of virtual desktop
UUIDs, instead of the previous x11 positional id, continuing the work on
This allows to set a rule with several desktops on Wayland.
On X11 it has no visible change for the user, but internally it uses the
more modern concept, helping to simplify the related code.
The relevant key on kwinrulesrc changes from `desktop` to `desktops`.
A kconf_update script handles the migration.
