The easiest way to implement that feature could be to add a 'Set > White Point' button to the Color Picker tool. This functionality exists in the levels tool already. Personally I'd prefer a gui similar to: http://pippin.gimp.org/plug-ins/color_correct/ for a combined levels (on luminance) and white point/gray point/black point offset. Since I don't find it entirely natural to modify the white point using levels. /Øyvind K.
