i.e., the integral of the pointwise product of both spectra over all
frequencies. The integration is split into three parts: The first part
ranges over the red part of the spectrum, its result is stored in
out.x

spectrum and is stored in out.y
, the third part ranges
over the blue part and is stored in out.z
