Until we have a robust accumulator, we now have
RandomGenerator>>#generateKey to seed our Randoms upon first usage
every image start.  This method generates 32 random bytes by
enumerating a variety of hard-to-guess information, using feedback and
chaining all prior values, making it basically impossible to guess.

So even quitting (without saving) and restarting the same image, you
get different seeds every time.
