Z order test 3
This test sets the z-index of the .far to 1 element and moves it "into" the screen by translating it along the z-axis. The z-index of the .near element is set to 2. No transform is applied to the .near element. Test passes if .far (coloured red) is rendered behind .near (coloured green).
NOTE: I'm not 100% if this test should pass or fail in its current state - the spec is ambiguous
