OptionalbezierBezier mode: 0 = off (default), 1 = cubic bezier.
OptionalbezierBezier control points [p1x, p1y, p2x, p2y] (only used when bezier = 1).
OptionaleasingSub-range start within the easing curve (0–1, default: 0).
OptionaleasingSub-range end within the easing curve (0–1, default: 1).
OptionallinkgroupLink group ID: non-zero values chain adjacent events together. 0 = none.
Optional fields shared by
