/**
 * EventDispatcher provides methods for managing queues of event listeners and dispatching events.
 *
 * You can either extend EventDispatcher or mix its methods into an existing prototype or instance by using the
 * EventDispatcher {{#crossLink "EventDispatcher/initialize"}}{{/crossLink}} method.
 * 
 * Together with the CreateJS Event class, EventDispatcher provides an extended event model that is based on the
 * DOM Level 2 event model, including addEventListener, removeEventListener, and dispatchEvent. It supports
 * bubbling / capture, preventDefault, stopPropagation, stopImmediatePropagation, and handleEvent.
 * 
 * EventDispatcher also exposes a {{#crossLink "EventDispatcher/on"}}{{/crossLink}} method, which makes it easier
 * to create scoped listeners, listeners that only run once, and listeners with associated arbitrary data. The 
 * {{#crossLink "EventDispatcher/off"}}{{/crossLink}} method is merely an alias to
 * {{#crossLink "EventDispatcher/removeEventListener"}}{{/crossLink}}.
 * 
 * Another addition to the DOM Level 2 model is the {{#crossLink "EventDispatcher/removeAllEventListeners"}}{{/crossLink}}
 * method, which can be used to listeners for all events, or listeners for a specific event. The Event object also 
 * includes a {{#crossLink "Event/remove"}}{{/crossLink}} method which removes the active listener.
 *
 * <h4>Example</h4>
 * Add EventDispatcher capabilities to the "MyClass" class.
 *
 *      EventDispatcher.initialize(MyClass.prototype);
 *
 * Add an event (see {{#crossLink "EventDispatcher/addEventListener"}}{{/crossLink}}).
 *
 *      instance.addEventListener("eventName", handlerMethod);
 *      function handlerMethod(event) {
 *          console.log(event.target + " Was Clicked");
 *      }
 *
 * <b>Maintaining proper scope</b><br />
 * Scope (ie. "this") can be be a challenge with events. Using the {{#crossLink "EventDispatcher/on"}}{{/crossLink}}
 * method to subscribe to events simplifies this.
 *
 *      instance.addEventListener("click", function(event) {
 *          console.log(instance == this); // false, scope is ambiguous.
 *      });
 *      
 *      instance.on("click", function(event) {
 *          console.log(instance == this); // true, "on" uses dispatcher scope by default.
 *      });
 * 
 * If you want to use addEventListener instead, you may want to use function.bind() or a similar proxy to manage scope.
 *

 *          // for more information.
 *          framerate: 20,
 *

 *          images: [image1, "path/to/image2.png"],
 *
 *          // DEFINING FRAMES:
 * 	        // the simple way to define frames, only requires frame size because frames are consecutive:
 * 	        // define frame width/height, and optionally the frame count and registration point x/y.
 * 	        // if count is omitted, it will be calculated automatically based on image dimensions.
 * 	        frames: {width:64, height:64, count:20, regX: 32, regY:64},
 *
 * 	        // OR, the complex way that defines individual rects for frames.
 * 	        // The 5th value is the image index per the list defined in "images" (defaults to 0).

 * 	        	[64,0,96,64,0]
 * 	        ],
 *
 *          // DEFINING ANIMATIONS:
 *
 * 	        // simple animation definitions. Define a consecutive range of frames (begin to end inclusive).
 * 	        // optionally define a "next" animation to sequence to (or false to stop) and a playback "speed".
 * 	        animations: {
 * 	        	// start, end, next, speed
 * 	        	run: [0,8],
 * 	        	jump: [9,12,"run",2]
 * 	        }
 *
 *          // the complex approach which specifies every frame in the animation by index.
 *          animations: {
 *          	run: {
 *          		frames: [1,2,3,3,2,1]
 *          	},
 *          	jump: {
 *          		frames: [1,4,5,6,1],
 *          		next: "run",
 *          		speed: 2
 *          	},
 *          	stand: { frames: [7] }
 *          }
 *
 * 	        // the above two approaches can be combined, you can also use a single frame definition:
 * 	        animations: {
 * 	        	run: [0,8,true,2],
 * 	        	jump: {
 * 	        		frames: [8,9,10,9,8],
 * 	        		next: "run",
 * 	        		speed: 2
 * 	        	},
 * 	        	stand: 7
 * 	        }
 *      }
 *
 * <strong>Note that the <code>speed</code> property was added in EaselJS 0.7.0. Earlier versions had a <code>frequency</code>
 * property instead, which was the inverse of speed. For example, a value of "4" would be 1/4 normal speed in earlier
 * versions, but us 4x normal speed in 0.7.0+.</strong>
 *
 * <h4>Example</h4>
 * To define a simple sprite sheet, with a single image "sprites.jpg" arranged in a regular 50x50 grid with two
 * animations, "run" looping from frame 0-4 inclusive, and "jump" playing from frame 5-8 and sequencing back to run:
 *
 *      var data = {
 *          images: ["sprites.jpg"],
 *          frames: {width:50, height:50},
 *          animations: {run:[0,4], jump:[5,8,"run"]}
 *      };
 *      var spriteSheet = new createjs.SpriteSheet(data);
 *      var animation = new createjs.Sprite(spriteSheet, "run");
 *
 *
 * <strong>Warning:</strong> Images loaded cross-origin will throw cross-origin security errors when interacted with
 * using a mouse, using methods such as `getObjectUnderPoint`, using filters, or caching. You can get around this by
 * setting `crossOrigin` flags on your images before passing them to EaselJS, eg: `img.crossOrigin="Anonymous";`

 * The Graphics class exposes an easy to use API for generating vector drawing instructions and drawing them to a
 * specified context. Note that you can use Graphics without any dependency on the Easel framework by calling {{#crossLink "DisplayObject/draw"}}{{/crossLink}}
 * directly, or it can be used with the {{#crossLink "Shape"}}{{/crossLink}} object to draw vector graphics within the
 * context of an Easel display list.
 *
 * <h4>Example</h4>
 *      var g = new createjs.Graphics();
 *	    g.setStrokeStyle(1);
 *	    g.beginStroke(createjs.Graphics.getRGB(0,0,0));
 *	    g.beginFill(createjs.Graphics.getRGB(255,0,0));
 *	    g.drawCircle(0,0,3);
 *
 *	    var s = new createjs.Shape(g);
 *	    	s.x = 100;
 *	    	s.y = 100;
 *
 *	    stage.addChild(s);
 *	    stage.update();
 *
 * Note that all drawing methods in Graphics return the Graphics instance, so they can be chained together. For example,
 * the following line of code would generate the instructions to draw a rectangle with a red stroke and blue fill, then
 * render it to the specified context2D:
 *
 *      myGraphics.beginStroke("#F00").beginFill("#00F").drawRect(20, 20, 100, 50).draw(myContext2D);
 *
 * <h4>Tiny API</h4>
 * The Graphics class also includes a "tiny API", which is one or two-letter methods that are shortcuts for all of the
 * Graphics methods. These methods are great for creating compact instructions, and is used by the Toolkit for CreateJS
 * to generate readable code. All tiny methods are marked as protected, so you can view them by enabling protected
 * descriptions in the docs.

	 * Provides a method for injecting arbitrary Context2D (aka Canvas) API calls into a Graphics queue. The specified

	/**
	 * Decodes a compact encoded path string into a series of draw instructions.

	 * The format uses a base64 character set, with each character representing 6 bits, to define a series of draw
	 * commands.
	 *
	 * Each command is comprised of a single "header" character followed by a variable number of alternating x and y
	 * position values. Reading the header bits from left to right (most to least significant): bits 1 to 3 specify the
	 * type of operation (0-moveTo, 1-lineTo, 2-quadraticCurveTo, 3-bezierCurveTo, 4-closePath, 5-7 unused). Bit 4
	 * indicates whether position values use 12 bits (2 characters) or 18 bits (3 characters), with a one indicating the
	 * latter. Bits 5 and 6 are currently unused.
	 *
	 * Following the header is a series of 0 (closePath), 2 (moveTo, lineTo), 4 (quadraticCurveTo), or 6 (bezierCurveTo)
	 * parameters. These parameters are alternating x/y positions represented by 2 or 3 characters (as indicated by the
	 * 4th bit in the command char). These characters consist of a 1 bit sign (1 is negative, 0 is positive), followed
	 * by an 11 (2 char) or 17 (3 char) bit integer value. All position values are in tenths of a pixel. Except in the
	 * case of move operations which are absolute, this value is a delta from the previous x or y position (as
	 * appropriate).
	 *
	 * For example, the string "A3cAAMAu4AAA" represents a line starting at -150,0 and ending at 150,0.
	 * <br />A - bits 000000. First 3 bits (000) indicate a moveTo operation. 4th bit (0) indicates 2 chars per
	 * parameter.
	 * <br />n0 - 110111011100. Absolute x position of -150.0px. First bit indicates a negative value, remaining bits
	 * indicate 1500 tenths of a pixel.
	 * <br />AA - 000000000000. Absolute y position of 0.
	 * <br />I - 001100. First 3 bits (001) indicate a lineTo operation. 4th bit (1) indicates 3 chars per parameter.
	 * <br />Au4 - 000000101110111000. An x delta of 300.0px, which is added to the previous x value of -150.0px to
	 * provide an absolute position of +150.0px.

/**
 * The EaselJS Javascript library provides a retained graphics mode for canvas including a full hierarchical display
 * list, a core interaction model, and helper classes to make working with 2D graphics in Canvas much easier.
 * EaselJS provides straight forward solutions for working with rich graphics and interactivity with HTML5 Canvas...
 *
 * <h4>Getting Started</h4>
 * To get started with Easel, create a {{#crossLink "Stage"}}{{/crossLink}} that wraps a CANVAS element, and add
 * {{#crossLink "DisplayObject"}}{{/crossLink}} instances as children. EaselJS supports:
 * <ul>
 *      <li>Images using {{#crossLink "Bitmap"}}{{/crossLink}}</li>
 *      <li>Vector graphics using {{#crossLink "Shape"}}{{/crossLink}} and {{#crossLink "Graphics"}}{{/crossLink}}</li>
 *      <li>Animated bitmaps using {{#crossLink "SpriteSheet"}}{{/crossLink}} and {{#crossLink "Sprite"}}{{/crossLink}}
 *      <li>Simple text instances using {{#crossLink "Text"}}{{/crossLink}}</li>
 *      <li>Containers that hold other DisplayObjects using {{#crossLink "Container"}}{{/crossLink}}</li>
 *      <li>Control HTML DOM elements using {{#crossLink "DOMElement"}}{{/crossLink}}</li>
 * </ul>
 *
 * All display objects can be added to the stage as children, or drawn to a canvas directly.
 *
 * <b>User Interactions</b><br />
 * All display objects on stage (except DOMElement) will dispatch events when interacted with using a mouse or
 * touch. EaselJS supports hover, press, and release events, as well as an easy-to-use drag-and-drop model. Check out
 * {{#crossLink "MouseEvent"}}{{/crossLink}} for more information.
 *
 * <h4>Simple Example</h4>
 * This example illustrates how to create and position a {{#crossLink "Shape"}}{{/crossLink}} on the {{#crossLink "Stage"}}{{/crossLink}}
 * using EaselJS' drawing API.
 *
 *	    //Create a stage by getting a reference to the canvas
 *	    stage = new createjs.Stage("demoCanvas");
 *	    //Create a Shape DisplayObject.
 *	    circle = new createjs.Shape();
 *	    circle.graphics.beginFill("red").drawCircle(0, 0, 40);
 *	    //Set position of Shape instance.
 *	    circle.x = circle.y = 50;
 *	    //Add Shape instance to stage display list.
 *	    stage.addChild(circle);
 *	    //Update stage will render next frame
 *	    stage.update();
 *
 * <b>Simple Interaction Example</b><br>
 *
 *      displayObject.addEventListener("click", handleClick);
 *      function handleClick(event){
 *          // Click happenened
 *      }
 *
 *      displayObject.addEventListener("mousedown", handlePress);
 *      function handlePress(event) {
 *          // A mouse press happened.
 *          // Listen for mouse move while the mouse is down:
 *          event.addEventListener("mousemove", handleMove);
 *      }
 *      function handleMove(event) {
 *          // Check out the DragAndDrop example in GitHub for more
 *      }
 *
 * <b>Simple Animation Example</b><br />
 * This example moves the shape created in the previous demo across the screen.
 *
 *	    //Update stage will render next frame
 *	    createjs.Ticker.addEventListener("tick", handleTick);
 *
 *	    function handleTick() {
 *          //Circle will move 10 units to the right.
 *	    	circle.x += 10;
 *	    	//Will cause the circle to wrap back
 * 	    	if (circle.x > stage.canvas.width) { circle.x = 0; }
 *	    	stage.update();
 *	    }
 *
 * <h4>Other Features</h4>
 * EaselJS also has built in support for
 * <ul><li>Canvas features such as {{#crossLink "Shadow"}}{{/crossLink}} and CompositeOperation</li>
 *      <li>{{#crossLink "Ticker"}}{{/crossLink}}, a global heartbeat that objects can subscribe to</li>
 *      <li>Filters, including a provided {{#crossLink "ColorMatrixFilter"}}{{/crossLink}}, {{#crossLink "AlphaMaskFilter"}}{{/crossLink}},
 *      {{#crossLink "AlphaMapFilter"}}{{/crossLink}}, and {{#crossLink "BlurFilter"}}{{/crossLink}}. See {{#crossLink "Filter"}}{{/crossLink}}
 *      for more information</li>
 *      <li>A {{#crossLink "ButtonHelper"}}{{/crossLink}} utility, to easily create interactive buttons</li>
 *      <li>{{#crossLink "SpriteSheetUtils"}}{{/crossLink}} and a {{#crossLink "SpriteSheetBuilder"}}{{/crossLink}} to
 *      help build and manage {{#crossLink "SpriteSheet"}}{{/crossLink}} functionality at run-time.</li>
 * </ul>
 *
 * <h4>Browser Support</h4>
 * All modern browsers that support Canvas will support EaselJS (<a href="http://caniuse.com/canvas">http://caniuse.com/canvas</a>).
 * Browser performance may vary between platforms, for example, Android Canvas has poor hardware support, and is much
 * slower on average than most other browsers.

	 * Draws the display object into a new canvas, which is then used for subsequent draws. For complex content

	 * this can provide for much faster rendering because the content does not need to be re-rendered each tick. The
	 * cached display object can be moved, rotated, faded, etc freely, however if its content changes, you must
	 * manually update the cache by calling <code>updateCache()</code> or <code>cache()</code> again. You must specify
	 * the cache area via the x, y, w, and h parameters. This defines the rectangle that will be rendered and cached
	 * using this display object's coordinates.
	 *
	 * <h4>Example</h4>
	 * For example if you defined a Shape that drew a circle at 0, 0 with a radius of 25:

	 * class for more information. Some filters (ex. BlurFilter) will not work as expected in conjunction with the scale param.
	 * 
	 * Usually, the resulting cacheCanvas will have the dimensions width*scale by height*scale, however some filters (ex. BlurFilter)

	 * @param {Number} x The x coordinate origin for the cache region.

	 * @param {Number} width The width of the cache region.

 * <b>This class is still experimental, and more advanced use is likely to be buggy. Please report bugs.</b>
 *
 * A DOMElement allows you to associate a HTMLElement with the display list. It will be transformed
 * within the DOM as though it is child of the {{#crossLink "Container"}}{{/crossLink}} it is added to. However, it is
 * not rendered to canvas, and as such will retain whatever z-index it has relative to the canvas (ie. it will be
 * drawn in front of or behind the canvas).
 *
 * The position of a DOMElement is relative to their parent node in the DOM. It is recommended that
 * the DOM Object be added to a div that also contains the canvas so that they share the same position
 * on the page.
 *
 * DOMElement is useful for positioning HTML elements over top of canvas content, and for elements
 * that you want to display outside the bounds of the canvas. For example, a tooltip with rich HTML
 * content.
 *
 * <h4>Mouse Interaction</h4>
 *
 * DOMElement instances are not full EaselJS display objects, and do not participate in EaselJS mouse
 * events or support methods like hitTest. To get mouse events from a DOMElement, you must instead add handlers to
 * the htmlElement (note, this does not support EventDispatcher)
 *
 *      var domElement = new createjs.DOMElement(htmlElement);
