Paul is pointing in the right direction. The matrix returned
from getTransformToElement is not a changeable matrix. So modifying it
does not change the document in any way.

You need to copy the matrix into one you create from the SVG root
element. Then you need
to set the matrix on something (similar to what Paul suggests).
