SUMMARY
[5.3] Krita fails to properly remember brush smoothing settings shortly after a fresh install. This could unfortunately confuse new Krita users who wonder why something about their brush smoothing feels not quite right.

STEPS TO REPRODUCE
(Follow these steps exactly as written!)

1. Launch Krita 5.3 as a completely fresh install. (In other words, wipe the Krita storage and cache from the Android System UI before launching.
2. Start a drawing.
3. In the Tool Options docker, set the brush smoothing to "Stabilizer" and disable "Delay."

4. Set the "Sample Count at Max Speed" to something high like 600. (Both min and max values should change at the same time since the values are linked by default.)
4. Quit Krita
5. Launch Krita a second time and start a drawing.
6. Look at the Tools Options docker.


OBSERVED RESULT
You will notice that the Sample Count values are no longer the same: the "Sample Count at Min Speed" returns back to 50.

EXPECTED RESULT
The Sample Count values should both remain the same, at the value you set it at the first time you launched Krita.

Fix the smoothing sliders to actually save their values

When a KisAspectRatioLocker is used to lock the sliders, their
direct signals should not be used. The signals of the locker should
be used instead.

The patch also adds proper documentation to
KisAspectRatioLocker :)
