description:
There appears to be some kind of problem with either
the parallel compositing algorithm or the way we're
setting the depth of each drawing object. When proc 1
draws something in proc 0's domain, proc 0 clobbers
it as a result of the depth comparison.  I've modified
the depth offset at which the historical swarm trajectories
get rendered such that they now appear on proc 0; the odd
thing is that I had to move them further away from the
camera for this to work: the opposite to what you'd
expect.  Anyway, seems to work now.
