Compositor: Make Hue Correct node wrap This patch makes the Hue Correct node as well as the Hue Correct VSE modifiers to wrap, such that no discontinuities occur for the red hue. Since it now wraps, the default curve preset now exempts the last point of the curve. A new CUMA_USE_WRAPPING flag was added to specify wrapping for curve maps. The implementation works by adding two virtual points before and after the terminal points in the curve map, such that their handles match, and would then produce a continues curve. This is a breaking change, since existing curves were also adjusted using versioning. However, the change will not be significant, since in most realistic cases, the terminal points will be close to each other, and even with wrapping, the connection will be very sharp, almost matching the old behavior.
