What if it had been

    the_context.move_to((p1 + p2a) / 2)
    the_context.line_to(p1 + (p2 - p1) * frac)
    the_context.line_to((p1 + p1a) / 2)
    the_context.stroke()
    the_context.move_to((p2 + p2a) / 2)
    the_context.line_to(p2 + (p1 - p2) * frac)
    the_context.line_to((p2 + p1a) / 2)
    the_context.stroke()
