vangel76andClaude Opus 5.5 d9205fa5f4 Curves: a natural cubic spline through the points, as After Effects ...

After Effects' Curves effect interpolates its points with a natural cubic
spline (zero curvature at the ends), clamped to 0..1: AE 2026 renders of an
RGB curve (0,0) (125,199) (255,255) and a Red curve (0,0) (128,44)
(255,255) (cases 962 / 963, ROUND4) give exactly the natural spline's values
on every grey step (0, 30, 59, 115, 164, 202, 227, 242, 250, 255 and 0, 0, 1,
6, 19, 44, 83, 135, 194, 255). EffectCraft used a monotone (Fritsch-Carlson)
spline: 34 / 67 / 125 / 171 ... on the RGB curve, up to 10/255 off (ROUND4
measured up to 6 levels on real projects); now within 1/255, CPU and GPU (the
same Hermite tables carry the spline's knot slopes). Lumetri's curves and
Glow's Arbitrary Map keep the monotone spline (not measured).
