Come to think of it, this optimized method is not so useful, it could just bring the user misunderstanding and not to efficient as I expected in the most cases. So, changed policy for transformation behaviors. it keeps the properties as others but leaves it to the backend implementation. Plus, this change contains the correct RenderUpdateFlag. You can refer the flag in the backend to figure out which kinds of properites has been updated Change-Id: Ibe0494712598a8161950b9ae2e22ac45bed1c47b
