Allegro shouldn't be calling rand() at all, IMHO.  If the user starts
using the blender, his output series from rand() will be mysteriously
affected.  Luckily the number of people using the dissolve blender _and_
expecting rand() to be unaffected is probably low.  I suppose we should
just use our own private, dumb-but-fast generator for this case
(something like what Paul Pridham posted).
