i came across this problem before
a non-uniform  scale constructor is really missing

i think you have 2 options

1) construct it by hand ( arbitrary coefficient constructor is available)

2) accept the fact that cgal , misses alot of matrix functionality , and use a full featured matrix library (for my case Eigen was perfect )

 All I found is this:
Aff_transformation_2(const Scaling tag, const RT &s, const RT &w= RT(1))
Is there any reason there is no:
Aff_transformation_2(const Scaling tag, const Direction_2 &s, const RT
&w= RT(1))
?
