You can change the transform attribute right here, since DOM/SVG
Events are always delivered in the UpdateManager Thread. BE CAREFUL
however because, AWT/Swing events are _not_ delivered in the UpdateManager
thread (they are delivered in the swing thread).

This won't work if the element (or any of it's ancestors)
have transforms associated with them.

This code will work regardless of transforms on the parents
of the element.
