does anyone have any idea how to build an equation that shiftes and transforms an input so that it fits a specified min and max?  a sort of f(min, max, input) = transformed and translated input.  i'm very sure this is possible, but i wouldn't even know where to begin.  i know it's possible, because it's basically the same thing the "Clouds" node for fbm: sets a floor color, a ceiling color, and calculates between them.    if any one knows how to make this equation, or even where to start, please let me know.  it would be helpful in tons of different situations.
