/** CCSprite is a 2d image ( http://en.wikipedia.org/wiki/Sprite_(computer_graphics) )
*
* CCSprite can be created with an image, or with a sub-rectangle of an image.
*
* If the parent or any of its ancestors is a CCSpriteBatchNode then the following features/limitations are valid
*	- Features when the parent is a CCBatchNode:
*		- MUCH faster rendering, specially if the CCSpriteBatchNode has many children. All the children will be drawn in a single batch.
*
*	- Limitations
*		- Camera is not supported yet (eg: CCOrbitCamera action doesn't work)
*		- GridBase actions are not supported (eg: CCLens, CCRipple, CCTwirl)
*		- The Alias/Antialias property belongs to CCSpriteBatchNode, so you can't individually set the aliased property.
*		- The Blending function property belongs to CCSpriteBatchNode, so you can't individually set the blending function property.
*		- Parallax scroller is not supported, but can be simulated with a "proxy" sprite.
*
*  If the parent is an standard CCNode, then CCSprite behaves like any other CCNode:
*    - It supports blending functions
*    - It supports aliasing / antialiasing
*    - But the rendering will be slower: 1 draw per children.
*
* The default anchorPoint in CCSprite is (0.5, 0.5).
