D21948: [colorcorrection] Add "Constant" mode

zzag added a comment.


  While I agree that splitting the night color manager into two entities makes sense, the requested changes are orthogonal to changes this patch introduces. No matter how you turn it, we need a switch to turn on/off the constant mode.
  
  Generic color correction manager should only deal with setting 1D/3D LUTs (3D LUTs is a topic for another discussion), gamma, and so on. Screen color temperature is night color manager's abstraction.
