White balance offset (for IR work)

I think there is no problem to extend the amplitude of the cursor “tint”. I just tested by replacing the current limit 5 by 8 and then use SpotWB, everything works fine.
But it is clear that the user will have been careful not to use these extreme settings only when needed.

There are now three possible solutions:

  1. or I “push” this change directly in “Master”
  2. or I open a new branch for testing
  3. or I do nothing
    What do you think ?
