bug:14259972 Ensure that translationZ is applied for true3dTransform property transformations, even if the node doesn't have any other transformation properties set. Additionally, use fuzzy compare for translationZ, similar to rotationX/Y, since they're expenive to leave set in rounding error cases. Change-Id: Idafa4423cc7751a8f433237b1f576aa7abb74f6e
