Note that the semantics changed too, they mutate the matrix. In 1.1  
SVGMatrix objects were immutable, so this is a pretty major change.  
Also, when matrix multiplying transforms, you usually want the right  
matrix to be the one updated. In other words, B = A * B is a more  
common operation than A = A * B, so the mutating semantics here are  
not very helpful.
