I see that some of the BGFX chains have a Saturation setting that is configurable via a slider. The crt-geom-deluxe doesn't have it as a slider. But, is it set any place in a JSON file that is editable?
I fully admit that I'm ignorant on how the chains work, but I didn't see that setting any place in a JSON file that the crt-geom-deluxe chain uses (that I can tell).
Is this something that has to be added to the BIN shader? Or can one edit the JSON file to "chain" it to the saturation.json and adjust the saturation that way? Or is it already using the saturation.json and I just don't get it?
