Title: Fixed some of the css transforms issues

The properties of transform-origin are not being returned by
computedCSS[attribute] but require calling
computedCSS.getPropertyValue(attribute)

Also it looked like there was a planned optimization caching the
previously computedStyle, but the previousElement was never stored so
the style got recomputed every time. Fixed that.
