The patches from yesterday where the start. These new 6 patches will move most of the other code around. After it the change is done for about 90%. Today I will send a bunch of other patches which will move some smaller parts like one which takes care of this r8g8b8 version check (I moved it to the top of the function but I could also keep it where it is and remove !Usage checks). I also need to enable set dynamic / softwareprocessing and a few others.

I think it is best to continue now. I'll prepare some of the other patches now.
