Compare API dox of Q_DECLARE_METATYPE:
"
Some types are registered automatically and do not need this macro:
* Pointers to classes derived from QObject
* QPointer<T>, QSharedPointer<T>, QWeakPointer<T>,
where T is a class that derives from QObject
"
This is a ABI-compatible change, as this just replaces explicitly
defined template code (by the Q_DECLARE_METATYPE macro use) with the
generic predefined one picking up pointers to QObject subclasses.
So instead of the custom explicitly template overload
template <>
struct QMetaTypeId< TYPE >
{ /**/ static int qt_metatype_id() {/**/} };
the predefined template overload one is picked up via
template <typename T>
struct QMetaTypeId : public QMetaTypeIdQObject<T>
{ /**/ };
template <typename T, int =
QtPrivate::IsPointerToTypeDerivedFromQObject<T>::Value ?
QMetaType::PointerToQObject :
/**/ 0>
struct QMetaTypeIdQObject
{ /**/ };
template <typename T>
struct QMetaTypeIdQObject<T*, QMetaType::PointerToQObject>
{ /**/ static int qt_metatype_id() {/**/} };
And thus the constexpr code using QMetaTypeId<T>::qt_metatype_id(),
for which all this is done, evaluates as before.

The old code calling
qRegisterMetaType<Plasma::T *>("T");
was broken, as it registered for the name "T", not the pointer
type "T*". Things still work though as that registration is also
covered due to
qmlRegisterInterface<Plasma::T>("T");
internally also calling
qRegisterMetaType<Plasma::T *>("T*");
so that in the end "T*" was registered and mapped to the right type.
Currently, I see that the network icons aren't visible enough. For example, I find it difficult to determine the signal strength of the network without peering. I would like these icons to be more visible, and therefore I propose to use 35% opacity for faded elements. As for me, this solution makes determining the signal level more convenient and the icons more informative.
Plasma dialogs are already marked as not being shown in the task manager
and the pager. We should similarly omit them from the task switcher, for
the same reasons.

We should use the normal arrow cursor when a list item is hovered.
The hovered state is depicted with a highlight already, so the hand
cursor is unnecessary and doesn't go well with the rest of the desktop.
The sizes of the context buttons on the list item were being overridden
for no apparent reason. Let's stop doing that so that the button sizes
are consistent with other PC3 button sizes.
Make sure the shadow item--which includes the hover effect, if present--can
be shown when the ToolButton is focused, and also always omit the shadow
when the ToolButton is flat.
Now all of them have a base height of units.gridUnit. Combined with
the standard 6px margins it works out to make all of these controls
a uniform 30px tall with the default Noto Sans 10 font. If the font
is changed or the size is increased, even to absurd levels, all of
them scale evenly.
The PC3 version was missing the clear button and show password button,
which the PC2 version has. This should allow us to port more things to
use the PC3 version.
relay->checkQueueing emits a signal to all observers. As it's a signal
anything can happen at that point. It's seemingly common for a receiver
to connect/disconnect a new visualisation which in turn alters
d->relays.
This broke when a foreach (with implicit shallow copy) was ported to a
for statement.

Currently, I see that the icons that show available and connected networks are not visible enough. For example, I find it difficult to determine the signal strength of the network without peering. I would like these icons to be more visible, and therefore I propose to reduce the opacity of faded lines. As for me, this solution makes determining the signal level more convenient and the icons more informative.
BUG: 423843
This changed the name of the types for which the classes where registered
from unnamespaced "Service", "ServiceJob", "DataSource" to the fully
namespaced "Plasma::Service", "Plasma::ServiceJob", "Plasma::DataSource",
so making the old names no longer known to the system and thus breaking
support for any invokable methods which use the unnamespaced type name.
And not only that, qmlRegisterInterface<T>("Name") also registered the
classes' pointer counterparts T* by the name "Name*", so here
"Service*", "ServiceJob*", "DataSource*". While the new again instead
does this with the fully namespaced names "Plasma::Service*",
"Plasma::ServiceJob*", "Plasma::DataSource*", so also breaking support
here.
This reverts commit 7c4f5c5f1e.
Level 1 is too large for this, as it's typically used for the entire
window or popup's title. The smaller level 2 is therefore more
appropriate so that when the parent window supplies its own level 1
heading, the calendar month label don't inappropriately be the same size.

Summary:
I recently noticed that `Kirigami.Units.devicePixelRatio` was `1.3` even though I was at the default 96dpi when writing a widget's config.
{F8287886}
There's 4 different `Units.qml`, and I'm not certain which does what. 2 are in `krigiami` and the other 2 are in `plasma-framework`.
```
$ locate /Units.qml | grep /usr/
/usr/lib/qt/qml/org/kde/kirigami.2/Units.qml
/usr/lib/qt/qml/org/kde/kirigami.2/styles/Plasma/Units.qml
/usr/lib/qt/qml/org/kde/kirigami.2/styles/org.kde.desktop/Units.qml
/usr/lib/qt/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml
```
* 2 years ago [`kirigami/src/controls/Units.qml`](https://github.com/KDE/kirigami/blame/master/src/controls/Units.qml#L75) (`/usr/lib/qt/qml/org/kde/kirigami.2/Units.qml`) was changed from `13/10 = 1.3` to multiply by `13*0.75` so that `9.75/10 = 0.975` (then `max(1, 0.975) = 1`).
-----
There's 2 files owned by `plasma-framework`. The `/styles/Plasma/Units.qml` binds PlasmaCore's `units.devicePixelRatio`, so that leaves `/styles/org.kde.desktop.plasma/Units.qml`.
```
$ pacman -Qo /usr/lib/qt/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml
/usr/lib/qt/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml is owned by plasma-framework 5.69.0-2
```
This patch edits the `org.kde.desktop.plasma` style, and fixes `qmlscene KirigamiDevicePixelRatioTest.qml`, and `plasmashell` widget configs, and `plasmoidviewer` widget configs.
The Kirigami patch is D29462
Test Plan:
You can edit `/usr/lib/qt/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml` then run:
* https://gist.github.com/Zren/621338b8cda7c550d7b43f8ea1ba71a7
* `qmlscene KirigamiDevicePixelRatioTest.qml`
and `Kirigami.Units.devicePixelRatio` should equal `1`.
