Make getComputedStyle(e).transform return correct values for non-transformable elements

getComputedStyle(e).transform currently doesn't return the correct 
values for non-transformable elements. Both FF and IE return the correct 
values. This patch makes getComputedStyle(e).transform return the 
correct value for non-transformable elements as well.
