add w520rec: recording with facecam and hardware audio mixer on the w520 - soft cursor to have it visible - automatic config of the internal cam - trick to leave the cam window always on top, like bar(1); requires sticky mode if used with riow - recording h264 + aac, made into mp4 on linux with ffmpeg - hj264 quality parameters are a bit high, but whatever, we get close to 60 fps
