CCSprite mesh manipulation?

Hey,

I whould like to split a CCSprite into 4x4 mesh, and then manipulate each vertex so I can make my own custom distortions to sprite. This was relatively simple to code with OpenGL ES 1.1, but 2.0 is just too much for me. Can someone point me in right direction?

Check PRKit for Cocos2d-x 2.0 or look at the code of the extension class CCScale9Sprite

Thanks for support!
Latest port of PRKit is crashing my Cocos2d-x 2.0.2, but the code itself will be helpfull enough to get me started.

Is this still valid?
I mean, I would like to do mesh distorting, but cocos2d-x latest version is far from 2.0
a) Is the PRKit capable of doing this in newer versions?
b) cocos2d-x provides now any other method for mesh manipulation?
