Implementation
According to code comments, the original code was done by Spencer and Peter, and worked fine in the 0.54 (motif only) release of GIMP. As far as I understand, this is the version based on the paper cited above, which was written for SIGGRAPH ‘95.
Later revisions (0.99.something until about 1.1.4) completely changed the algorithm used, until it bore little resemblance to the one described in the paper above.
The 0.54 version of the algorithm was then forwards ported to 1.1.4 by Austin Donnelly.
It is unclear to me how much of the original algorithm is in the current implementation at this point.
