Set initial rendering to 0 iterations

 - The initial rendering used to be 0 iterations, but I had changed this
   due to the bug where I was forgetting to set the initial string length.
   Now that the string length bug is fixed, I can return to starting at
   the more obvious place: the system's "init" string.
