The ultimate goal of working in a linear light color space is both clear and noble.
The purpose of the constant background converting back and forth between two tone curves, sRGB TRC and linear gamma, is not clear at all. "In service of the noble goal" doesn't explain *why* the conversions are done over and over again instead of just once. I really, really, really want to know why those relentlessly repeating background conversions between sRGB TRC and linear gamma are happening. But I will stop asking. And maybe some kind soul will send a private email giving an explanation that I can understand. I was excited to find out that the latest LCMS can do color conversions involving negative floating point numbers. If the Gimp code is only 20% finished, then perhaps the information I just gave about the new ability of LCMS to do conversions involving negative floating point numbers might be pertinent to crafting the remaining 80%. But if not, then I apologize for posting it.
