Comment by reviewer (Jehan):

This was submitted through gimp-developer mailing list, by the same
author as the original Spyrogimp in script-fu, but this time in Python.

It does more than the original plug-in, with some automatic preview (by
drawing directly on a temporary layer, not as a GEGL preview), and using
the current tool options (current brush, etc.). The new API is similar
yet different. The much evolved possibilities makes that I don't think
it is worth trying to map 1-1 the new API to the old one, so I just let
the old plug-in next to the new one, with a different name.

Note finally that the author also contributed a new Spyrograph operation
to GEGL, yet with the comment: "The GEGL spyrograph operation is very
basic, and untested from gimp. I intend to keep developing it, since I
thought that on-canvas interaction would be very user-friendly. However,
I am not sure I will be able to get it work in a way that makes the
on-canvas interaction interactive enough.

Even if I do, it will not do what the Python plugin can do. It will be
much more basic."

So let's just integrate this evolved version of Spyrogimp for now. :-)
