This is the last missing piece of the OCIO workflow.

Lutbaking allows you to turn any given HDR, or, when using OCIO right, any given image at all, into a normalised display reffered image.

Ideally, you'd use the Lut docker to determine the exact look you want, and then use a 'bake lut' option to have that look becoming the end result.(Or at the least generate an image with the baked colours).

Uses:
* Converting hdr images for consumer use. Web, etc.
* Fast colour correction alternative.

Ceveats: We might want to check how other programs do this...
