Extend final point in closed degenerate hairline segments
For single-contour paths (MLZ), the close is ignored during iteration,
and we instead process the 'Done', which does extend in both directions.
But if there's a second contour (MLZM), then we process the 'Close', and
only extend the degenerate segment in one direction. Depending on where
the path was positioned (relative to pixel centers), this led to some
contours not drawing at all.
