Re: reversable, but not 1D color transforms in config.ocio

Cool, that's what I thought.  Just making sure you hadn't snuck anything else in there I hadn't noticed!

And yeah re: LAB space vs Log space for doing the actual sharpen --that's an interesting idea I'll have to look into that more for sure.  I know that wide gamut devices will be here soon and we really can't be going off into l*a*b* and back to do this stuff.  I'm starting with pipeline parity with what we do today, but I know there will be a whole bunch work to go back and move all of this to an aces workflow someday, and there's no room for this nonsense there.

I didn't do much other than read Doug's post and force myself to re-read the CIE L*a*b* formula.

The matrices to XYZ are Illuminant C adapted from D65. Feel free to replace that component as required.
