This will generate and apply this correction table to the led gamma setting.

Sorry I haven't yet had a chance to give this a test, but thank you, it's in my backlog!

That you would even consider adding it, is a honor. As you see, it makes no attempt to alter the memory that is created, it simply replaces the values. It has been working well in my code base and allows me to change gamma settings on the fly at will now. Again, thanks for considering it, been using this lib for years, and would be fantastic to have even this small contribution.

Merged with the knowledge that this breaks the CMakeLists.txt build which I will fix shortly.

Thank you!
