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