BTW I think the below may be fine for the PCS to Device (B2A0) tag since we
are just applying a simple transfer function to a single channel,ie to
luminance only, and BPC can be built into this transform.  I wonder, though,
if it creates complications on the soft proof leg, Device to PCS (A2B0),
because it will be this tag (I assume) that PS coordinates with most for
soft proofing.
