2025.10.16(3.9.1)
- Change the white balance range back to [-1200, 1200].
  Sorry for the multiple changes to the white balance range and the conflict with some capture software's configuration file.
  The white balance of a camera is a hardware parameter, just like exposure and gain, not a coefficient of a software algorithm, remapping its range is not advisable. Also, thanks to some users and Rumen for their suggestions.
