-webkit-transform should have good initial value

(ignore that the test says it is failing in that report)

-webkit-transform doesn't have a nice value when a parent of display none.

It should return "none" in this case I think (as should an untransformed element).

Patch

This patch also fixes getComputedStyle() to return 'none' for elements with no tranform (previously, it would return an identity matrix).
