This is an RFC set for a color pipeline API, along with implementations
in VKMS and amdgpu. It is tested with a set of IGT tests that can be
found at [1]. The IGT tests run a pixel-by-pixel comparison with an
allowable delta variation as the goal for these transformations is
perceptual correctness,
