[Feature Request] Separate Monitor Control

[OdinVex]

I've got two different monitors that have drastically different brightness differences when using Redshift. I'd like to set brightness ranges specific to each monitor. Maybe it is gamma? I'd like to have a uniform brightness regardless of monitors (within a reasonable range of difference, I know monitors are all different from one another, even if calibrated).

@OdinVex I saw that there are script-hook which may help.

It would be far better to have the smoothness of transitioning per monitor built-in. Would you accept patches for this, @jonls ?
