We could want to stop the recording without expanding the notification
panel and show sensitive info.
Long pressing on the red dot moves it to the opposite side,
in case the user wants not to cover specific elements on the screen.

Add also a low quality option that still gives a good recording
reducing a lot the final file size (useful when sharing the screenrecord
on data connections).
