Kari,
   Yes youre correct. I've discovered ( in Pass 2) to get less smoothing,
you need to increase count, or else there can be some strange artifacts
(such as black or white lines at borders). With error_bound of 0.7 I've gone
as low as count 10 without artifacts (depends on the image) For this image I
used error_bound 0.400 and count 150. A Count of less than 100 tended to
produce artifacts around the feet. Raising count in Pass 2 does not seem to
improve image quality but it does prevent artifacts from appearing, so its a
matter of finding the magic number it seems. Its a balancing act because a
larger count slows down Pass 2
All the above info is for the second, quick smoothing pass. For Pass 1 I
used count 200, error_bound 0.180, recursion_limit 12 (both passes),
nearest_count 1 (both passes), and brightness 1.4 (both passes).

Thanks,
George Pantazopoulos
