The first method sets it to a specific rotation, not an identity matrix
so it seems that is what you
want.

setToRotation does exactly what the 'rotate' function' does in the SVG
transform attribute.
I'm a little afraid that you are trying to adjust a general affine
transform (that may have non-uniform
scaling and skew) so that it has a specific rotation. I'm afraid that is what
you want to do because you can't
really do it without coming up with a perhaps non-sensical definition of
rotation...
