That's unrelated. I simply meant that I currently work in linear space
anyway, and what I meant involves no code changes, just converting
between color profiles during testing to ensure more accurate
interpolation. (my point also was that it's hard to tell if it's doing
something better, when the distorted interpolation presents
significant artefacts obscuring it). Anyway -- okay, I won't do that.
