Dear developers, why you do this?
Again non-trivial values returned by copy instead const reference?
Hi Marat,
I have replied it on the github. Feel free to let me know your thoughts. Thanks. 
Thanks Marat Yakupov, you’re right.
I think these getters should also be added as const function, like
const CCSize& getSize() const;
The current work is not perfect yet.
Thanks
