Using the very same focal blur sample sequence for all frames of an
animation is by design, not by error; I'm pretty sure both earlier 3.7
betas and 3.6 did the same (they used a pseudo-RNG instead of a Halton
sequence, but unless I'm totally mistaken they started the PRNG all over
again with the very same seed for each frame). There appears to be
consensus among the POV-Ray animators that static noise should be
favored over dynamic noise.
