/*
    The 68-point annotations for the iBUG 300-W face landmark dataset.
    See this picture:
        https://ibug.doc.ic.ac.uk/media/uploads/images/annotpics/figure_68_markup.jpg
    NOTE: the indexes in the picture are 1-based, so the actual C++ indexes are less 1.
    NOTE: "Right" and "left" refer to the face being described, so are the mirror of the
    side that an onlooker (from the front) would see.
