sourceChromaticityQ16()

bool fl::anonymous_namespace{source_xyz.cpp.hpp}::sourceChromaticityQ16	(	Chromaticity	c,
		i32(&)	out[2] )

A chromaticity, converted from float by its bits, that is real and usable: inside the open unit square with a non-zero y.

The float check it replaces (NaN, 0 < x < 1, 1e-6 < y < 1) is kept, with y's floor at one s16.16 step – a smaller y would quantise to zero and be divided by.
