Static Public Member Functions
static FASTLED_FORCE_INLINE bool	active (const u8(&e)[3]) FL_NO_EXCEPT

static FASTLED_FORCE_INLINE u8	apply (u8 b, u8 d) FL_NO_EXCEPT
	Add the offset to a source byte, before scaling. Black is never lifted.

static FASTLED_FORCE_INLINE void	clear (u8(&d)[3], u8(&e)[3]) FL_NO_EXCEPT

static FASTLED_FORCE_INLINE void	init (u8(&d)[3], u8(&e)[3], const u8(&scale)[3], u8 frame) FL_NO_EXCEPT
	Set up `e` from the per-channel brightness scale and `d` from `frame`.

static FASTLED_FORCE_INLINE u8	offset (u8 q, u8 range) FL_NO_EXCEPT
	Q scaled into `[0, range)`: the offset for one channel.

static FASTLED_FORCE_INLINE u8	phase (u8 frame) FL_NO_EXCEPT
	The frame's offset pattern value Q: `frame` wrapped to `VIRTUAL_BITS`, bit-reversed so consecutive frames land far apart (0,1,2,3 -> 0,128,64,192), then shifted to the middle of its bin.

static FASTLED_FORCE_INLINE void	reseed (u8(&d)[3], const u8(&e)[3], u8 frame) FL_NO_EXCEPT
	Re-point `d` at `frame`, keeping the ranges `init` left in `e`.

static FASTLED_FORCE_INLINE void	step (u8(&d)[3], const u8(&e)[3]) FL_NO_EXCEPT
	Next pixel: toggle each offset to its complement in `[0, e]`, so neighbours dither in opposite directions.

static FASTLED_FORCE_INLINE void	stepChannel (u8(&d)[3], const u8(&e)[3], int c) FL_NO_EXCEPT
	`step` for a single channel (drivers that pre-step their first byte).
