/**
* cc.Sprite is a 2d image ( http://en.wikipedia.org/wiki/Sprite_(computer_graphics) )
*
* cc.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 cc.SpriteBatchNode then the following features/limitations are valid
* - Features when the parent is a cc.BatchNode:
* - MUCH faster rendering, specially if the cc.SpriteBatchNode 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 cc.Node, then cc.Sprite behaves like any other cc.Node:
* - It supports blending functions
* - It supports aliasing / antialiasing
* - But the rendering will be slower: 1 draw per children.
*
* The default anchorPoint in cc.Sprite is (0.5, 0.5).
* @class
* @extends cc.Node
*
* @param {String|cc.SpriteFrame|HTMLImageElement|cc.Texture2D} fileName The string which indicates a path to image file, e.g., "scene1/monster.png".
* @param {cc.Rect} rect Only the contents inside rect of pszFileName's texture will be applied for this sprite.
* @param {Boolean} [rotated] Whether or not the texture rectangle is rotated.
* @example
*
* 1.Create a sprite with image path and rect
* var sprite1 = new cc.Sprite("res/HelloHTML5World.png");
* var sprite2 = new cc.Sprite("res/HelloHTML5World.png",cc.rect(0,0,480,320));
*
* 2.Create a sprite with a sprite frame name. Must add "#" before frame name.
* var sprite = new cc.Sprite('#grossini_dance_01.png');
*
* 3.Create a sprite with a sprite frame
* var spriteFrame = cc.spriteFrameCache.getSpriteFrame("grossini_dance_01.png");
* var sprite = new cc.Sprite(spriteFrame);
*
* 4.Create a sprite with an existing texture contained in a CCTexture2D object
* After creation, the rect will be the size of the texture, and the offset will be (0,0).
* var texture = cc.textureCache.addImage("HelloHTML5World.png");
* var sprite1 = new cc.Sprite(texture);
* var sprite2 = new cc.Sprite(texture, cc.rect(0,0,480,320));
*
* @property {Boolean} dirty - Indicates whether the sprite needs to be updated.
* @property {Boolean} flippedX - Indicates whether or not the spirte is flipped on x axis.
* @property {Boolean} flippedY - Indicates whether or not the spirte is flipped on y axis.
* @property {Number} offsetX - <@readonly> The offset position on x axis of the sprite in texture. Calculated automatically by editors like Zwoptex.
* @property {Number} offsetY - <@readonly> The offset position on x axis of the sprite in texture. Calculated automatically by editors like Zwoptex.
* @property {Number} atlasIndex - The index used on the TextureAtlas.
* @property {cc.Texture2D} texture - Texture used to render the sprite.
* @property {Boolean} textureRectRotated - <@readonly> Indicate whether the texture rectangle is rotated.
* @property {cc.TextureAtlas} textureAtlas - The weak reference of the cc.TextureAtlas when the sprite is rendered using via cc.SpriteBatchNode.
* @property {cc.SpriteBatchNode} batchNode - The batch node object if this sprite is rendered by cc.SpriteBatchNode.
* @property {cc.V3F_C4B_T2F_Quad} quad - <@readonly> The quad (tex coords, vertex coords and color) information.
