Indeed, this is based on the "Camera WB" setting.  The "Camera WB"
setting seems to ignore the WhiteBalanceBias.

I suppose it would a bit more accurate, atleast in the case of the
"Fluorescent" setting, because the values there are based on common
types of Fluorescent lighting found and not interpolated.  I will send
the intermediate values (I noticed that the UFRaw documentation has
information on how to do this.  I will follow those instructions).

Changing this report priority to "minor" based on the discussion.
