You're adding a subpath to the path every iteration, so previously
drawn subpaths are getting redrawn -- the first one 12 times, the
second one 11 times, and so on.
Anti-aliasing, in combination with a fractional line width, is
causing the line "spreading" effect.
You need [apath removeAllPoints] inside the loop after [apath
stroke], or move [apath stroke] outside the loop.
