It is convenient for the operating system to use a circular list so that when it reaches the end of the list it can cycle around to the front of the list. I am using several of them right now, because of how easy it is to add items, and to programmatically say "do this action to every item in the list". The basic idea of AffineTransform is to represent the transform as a matrix and Linear Algebra - Linear transformation question, Theoretically Correct vs Practical Notation.
