Another plug-in to do combined adjustments of whitebalance, levels and
saturation can be found at
http://pippin.gimp.org/plug-ins/color_correct/ I haven't touched the
code of the plug-in in a long time, and the user interface have a few
rough edges, but it provides live preview in the image, as well as the
ability to do an initial automatic whitebalance / white balance based
on a picked neutral grey, as well as adjusting the blackpoint.
