- is there a PDB function callable for doing the Map/Rotate Colours?
I see it's a GEGL operation in 2.10, but it was there also on 2.8, so maybe there is a "legacy" pdb-equivalent function

Technically: plug-in-rotate-colormap() but... it doesn't take parameters besides a drawable, so is pretty much unusable.
