Adding const to getter methods

cocos2d-x C++
#1

I noticed that getter methods of cocos2d-x are not const declaration.
For example CCNode::getPosition().

Library declaretion is as follows.

virtual const CCPoint& getPosition();

I hope it would be as follows.

virtual const CCPoint& getPosition() const;

Is there a plan for adding const to them?

#2

This has already been done in version 3.
