    Offset values are obtained from the following formulas:

      offset-height = height - min-height

    The offset-scaled-width and heigth are obtained by extending the line from
    [min,min] to [W,H] and taking the intersection with a square that starts at
    [min,min] and ends at [max,max].

    The extending line forms right angle triangles with the [min,min]->[max,max]
    box that enable us to derive the following formulas

    We also want the result to always be smaller than the input (pdp > everywhere else)
    by some scaling factor.
