    - a BUG in the code applying gamma 2.2 for exr input was fixed.
2020.05.16
    - add utility-muxer\concat script, a quick way to stitch multiple video clips together.
      this is a muxer script so no re-compression in the process.
    - add utility-muxer\add-audio script, you can add/ or replace audio to video(s).
      again this a muxer so the video codec is untouched.
2020.05.15
    - fixed a bug in video\prores script.
2020.05.09
    - script\utility-muxer\qTool-muxer-add-thumbnail.com is updated.
      it generates icon thumbnails for mp4 files. this is a muxer script,
      which means video's codec is un-changed, only meta-data is updated.
2020.05.06

2020.04.29 [v4]
    - This version is a major update.
      all the main scripts (image and video) scripts now support multiple input files.
