This structure represents the 3x2 matrix :
In 64-bit applications, this structure is just like the Core Graphics
CGAffine data structure. In 32-bit applications, the Core Graphics data structure is equivalent to
v. Most of the time, you should use the
v data structure, which changes size depending on architecture.
The CGAffineTransform describes functions for creating and manipulating matrixes of this form.
