Make sure you understand this: the line IS zero length, but the pen's ink has both nonzero height and width. If you don't want a zero-length line drawn, don't attempt to draw it in the first place. It does make you think points aren't at the corner of pixels, but when you deal with fat or strange rectangular pen sizes, it doesn't seem so strange... Apple isn't merely right in its implementation, it's downright subtle and a pleasant change. - Brian
