Z order test 1 (transposed DOM)
This test moves the element .far "into" the screen by translating it along the z-axis. No transform is applied to the .near element. .far appears after .near in the DOM tree so it will be rendered later. Test passes if .near (coloured green) is rendered behind .far (coloured red).
This test is identical to z-order test 1 except that the .near and .far elements have been transposed in the DOM tree.
NOTE: I'm not 100% if this test should pass or fail in its current state - the spec is ambiguous
