The Dirac one tries to pretend to be both:
- vorbis like: GP64 * gp64_rate = decode/muxing time + jitter
- granuleshift like: GPH+L * gphplusl_rate = presentation time + jitter
And if one knows how to decode it fully, the jitter disapears. So it is
a bit quantum: it sometimes behaves like granuleshift and sometimes
linear, neither of which give you 100% precision.
