------- Additional Comments from Dirk Schulze <vbs85 at gmx.de>
I misunderstood the documentation of CGAffineTransform. The CGAffineTransform
is the transpose of cairo_matrix. That means
a is xx on cairo, [1,1] on CGAffineTransform
b is yx on cairo, [1,2] on CGAffineTransform
c is xy on cairo, [2,1] on CGAffineTransform
d is yy on cairo, [2,2] on CGAffineTransform
and so on.
That means the handover of the values have to be AffineTransform(a, b, c, d, e,
f).
