: What is this "plateau-free noise"?

  AFAIK it's the following:
  The fractal noise function used by, for example, the bozo pattern should
return values between 0 and 1, but instead it returns values that are outside
that range (0 and 1.5 or something like that). This value gets then clamped
to the range 0 - 1 (ie. all values greater than 1 are converted to 1).
  This causes flat areas of height 1 in the bozo pattern.
