Classes
struct	SplitBound
	A bound on the split, as (numerator + slope * s) / denominator with a positive denominator. More...

Functions
i64	divideWhiteQ16 (i32 numerator, i32 denominator) FL_NO_EXCEPT
	(numerator << 16) / denominator as s16.16, kept in i64.
bool	narrowTotalForPair (const SplitBound &lower, const SplitBound &upper, i64 *low, i64 *high) FL_NO_EXCEPT
	The totals at which lower <= upper holds, narrowed into [*low, *high].
SplitBound	normalizedSplitBound (i32 numerator, i32 slope, i32 denominator) FL_NO_EXCEPT
	Fold a negative denominator into the numerator and slope, so every bound compares the same way round.
i32	scaleWhiteQ16 (i32 value, i32 factor) FL_NO_EXCEPT
	Scale an s16.16 value by an s16.16 factor, rounding to nearest.
i64	splitBoundAt (const SplitBound &bound, i64 total) FL_NO_EXCEPT
	value at total s, in s16.16.
bool	splitBoundInRange (const SplitBound &bound) FL_NO_EXCEPT
	Whether every part of a bound stays inside the range the accumulators were sized for.

Variables
constexpr i32	kTwoWhiteBoundSlack = kWhiteSlack / 2
	How far past full drive the bounds let an RGB drive reach.
constexpr i32	kTwoWhiteMaxColumn = 8 * 65536
	The largest magnitude a per-white column or a solved drive may reach before the pairwise bounds stop fitting.
constexpr i32	kWhiteFullDrive = 65536
	Full drive, as an s16.16 raw value.
constexpr i32	kWhiteSlack = 64
	The same allowance, uniform, for the two-white (RGBWW) path.
constexpr i32	kWhiteSlackAtUnitColumn = 64
	Slack on the drive bounds, for an emitter whose XYZ column peaks at 1.
