Alex,

sorry, I though you misunderstood something, the question was not how to apply
camera wb, it was how to get the temerature value for display. 

As I know we can take LibRaw's imgdata.color.cam_mul[] and compute it be a
iterate function. See also Adobe DNG specification, section "Translating Camera
Neutral Coordinates to White Balance xy Coordinates".

Looks like http://www.brucelindbloom.com/index.html?Eqn_XYZ_to_T.html is a
implementation we want of.

Jens
