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.
