What exactly do you think we should add? Effectively the part starting with the second paragraph under "Discussion" at http://developer.apple.com/mac/library/documentation/GraphicsImaging/Reference/CGAffineTransform/Reference/reference.html#//apple_ref/doc/c_ref/CGAffineTransform and going through the two linear equations defining x' and y'. Plus a bit that says how the linear list of arguments passed to transform() maps to the 2-dimensional array of numbers in the transformation matrix. -Boris
