We now put butt line cap vertices in the correct position, vertical to line direction. We still pretend we're walking on the pen polygon though, so it's probably possible to make this produce weird-looking output by making the line cap line segments very short. In practice, for butt line caps of real-world paths, it's a big improvement though.
