[Gegl-developer] Color temperature correction GeglOperation

[Jan Heller]

Hi,

 attached is a GeglOperation performing color temperature
 correction. This is of course analogical to the
 whitebalance operation that is already in the Gegl source
 tree, though it uses photographer friendly input values. It
 has two parameters, estimated temperature of the light
 source in K the image was taken with and Corrected
 estimation of the temperature of the light source in K. The
 computation is a rather simple linear interpolation of a
 data table. I wrote it to better familiarize myself with
 Gegl and I am posting it here in hope it will be useful for
 others.

 Regards,
   Jan
