Title: convertContentSize(To/From)Points Yields 0 on Normalized

When using convertContentSize(To/From)Points and you have either CCSizeUnitNormalized, CCSizeUnitInsetPoints or CCSizeUnitInsetUIPoints on your top node, you will get 0 for that one, because the top node has no parent. (nil.something == 0).
