Currently Folio's settings are being written to the main KConfigGroup of the
containment, when can interfere with other generic containment settings.
ShellCorona in plasma-workspace also expects the settings to be in
sub-config group when it preserves them when changing containments.
This commit moves all of the settings to its own config group, and also
consolidates config read/write for favourites and pages into
FolioSettings.
This merge request expands upon the folio and halcyon background blur effects, making the folio background blur include the backgrounds of folder icons, the favorites bar, and wallpaper selector, and for halcyon, it now includes the folder icons, app library, search, and wallpaper selector. To accomplish this, a mask layer plugin was created to easily attach to these elements. This way, we can use a `OpacityMask` to cut out from the existing blur layer, thus hopefully keeping the performance cost low. And with my limited testing, it does at least seems to run about the same on my oneplus 6t, though it is not really a low end device, so I can not fairly judge the impact for something slower (eg. PinePhone). To be on the safe side, a third option was also added to the folio settings, allowing for the ability to toggle back to the old functionality if needed.
This MR does several things as a followup to
https://invent.kde.org/plasma/plasma-mobile/-/merge_requests/748:
- Use the word "lock" instead of "sleep" since we are locking the
device, not putting it to sleep
- Simplify usage by using existing MouseAreas instead of including our
own for this feature (I encountered several focus captures in folio that prevented the
SwipeArea from getting events)
The wallpaper blur causes extreme lag on the PinePhone, best to disable it for now by default, and hide it behind a setting. :C
