	)

Set up a profile adapted to the blending.

darktable built-in color profiles are chroma-adjusted such that they define a [D65 RGB -> D50 XYZ] transform, which is expected by CIE Lab and the ICC pipeline. Since JzAzBz expects an XYZ vector adjusted for D65, we apply a Bradford transform on the profile primaries to output D65 XYZ. The updated primaries are stored in matrix_out. This is valid only in the context of blending with JzAzBz color space. The resulting XYZ is used only to define masks and not re-injected into the pipeline.

The initialized profile may only be used to convert from RGB to XYZ.
