Here's a tip. Try to understand GEGL's data formats. You can find some
information here:
http://gegl.org/babl/
Try to learn the colorspaces and also the ranges of the inputs and
outputs.
Most GIMP plug-ins will have to be *rewritten* for GEGL. You can adapt
code, but simply copying code without following it will not work.
