Fix is not easy though: 1. allowing will not work because IGAM is before ICSC so RGB gamma would be applied on YUV pixels. 2. Moving OS gamma to DGAM or RGAM resulted in weird artifacts. Ultimately the root cause for these artifacts was due to handling end points and the fact that YUV->RGB conversion will frequently "overshoot" FP 1.0 value. DCE has a single end point and slope, so we would take max. In nightlight mode, blue channel is reduced, sometimes to flat 0 line, but red is virtually unchanged. Any "overshot" in blue will be clipped to 1 (max R,G,B) instead of max blue value. [How] Fortunately, this can be fixed on DCN where we have end point and slope for all three color channels. We cannot fix this problem on DCE. Other things fixed: - switch (back) to using RGAM for OS gamma instead of IGAM - add coeffs for 709 YUV->RGB (we used RGB->YUV for both conversions) - switch color temperature method to scaled bradford - otherwise we would have clipping problems that caused us to switch to IGAM for OS gamma in the first place. - comments and some minor improvements - there are some more issues but they will be addressed in separate commits.
