We'd like to build the notes' position from 0 to infinity,

position would actually be
judgeline - positiveposition

measure * measuresize + fraction * fractionsize
In practice, since we use a ms-based model rather than a beat one,
we just do regular integration of
position = sum(speed_i * duration_i) + speed_current * (time_current - speed_start_time)
