With Python binding, it gets very easy to test new functions. I've been wondering if we need C counterparts, but really since it's a GObject Introspection binding, if a function succeeds there, it should also succeed in C code. For now, I'm testing a few of GimpPalette API. Not all of it yet. Also I test both the direct C binding and PDB procedure since in some cases, one or the other may not properly working. See #10885.
