The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
Summary:
Same as D28507
Disable screen edge modification, but allow the user to open an edge context menu and see the settings.
To set an edge immutable, just add `[$i]` right after the entry in `ElectricBorders` group, although the edges settings are shared between some `[Effect-something]` group under the key `BorderActivateSomething`.
Since one entry like `BorderActivateSomething` lists all edges that use this effect, it doesn't make sense to set it immutable.
Test Plan:
In `kwinrc`, set the `ElectricBorders` and/or `Windows` group immutable or any entry.
```
[ElectricBorders]
BottomLeft[$i]=None
Left=None
Right=None
Top[$i]=None
[Windows][$i]
ElectricBorderCornerRatio=0.29
ElectricBorderDelay=300
ElectricBorderMaximize=false
ElectricBorderTiling=true
ElectricBorders=2
```
