2260 # (q%2) -- q2 (y)
2262 # (q%-1) -- the vector {q1, q2, q3}

2330 # dq_absolute = q2 * q1_inverse
2331 # dq_relative = q1_inverse * q2
2333 # absolute involves un-doing q1's rotation (making it the reference frame), then applying q2.
2334 # relative involves applying q2 (maintaining the original reference frame), then undoing q1.
