Hi, somewhat confusingly, the 'real' function has the same name, but
is in app/core/gimpimage-colormap.c. It isn't very exciting to look at
though, it just returns image->colormap. The pdb function that mangles
the values around a bit is in app/pdb/image-cmds.c with the name
image_get_colormap_invoker, generated from tools/pdbgen/pdb/image.pdb,
where it is again called image_get_colormap (without gimp_). :)
