TweenEasing
EnumSource: CameraTween.h
Description
Easing curves for camera tween interpolation.
All four curves map a normalised progress [0, 1] to an eased value [0, 1]. The easing math is computed in Q16.16 fixed-point (raw values 0..65536) so that the hot path contains zero floating-point operations on the Fixed16 (ESP32-C3) scalar path.
