	/**
	 * 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);
	 *

	 * event to be notified when a set time interval has elapsed.

	 * when under high CPU load. The Ticker class uses a static interface (ex. `Ticker.framerate = 30;`) and
	 * can not be instantiated.

	/**
	 * Encapsulates the properties and methods associated with a sprite sheet. A sprite sheet is a series of images (usually
	 * animation frames) combined into a larger image (or images). For example, an animation consisting of eight 100x100
	 * images could be combined into a single 400x200 sprite sheet (4 frames across by 2 high).
	 *
	 * The data passed to the SpriteSheet constructor defines:<ol>
	 * 	<li> The source image or images to use.</li>
	 * 	<li> The positions of individual image frames.</li>
	 * 	<li> Sequences of frames that form named animations. Optional.</li>
	 * 	<li> The target playback framerate. Optional.</li>
	 * </OL>
	 *
	 * <h3>SpriteSheet Format</h3>
	 *
	 * SpriteSheets are an object with two required properties (`images` and `frames`), and two optional properties
	 * (`framerate` and `animations`). This makes them easy to define in javascript code, or in JSON.
	 *
	 * <h4>images</h4>
	 * An array of source images. Images can be either an HTMLImage
	 * instance, or a uri to an image. The former is recommended to control preloading.
	 *
	 * 	images: [image1, "path/to/image2.png"],
	 *
	 * <h4>frames</h4>
	 * Defines the individual frames. There are two supported formats for frame data:<OL>
	 * <LI> when all of the frames are the same size (in a grid), use an object with `width`, `height`, `regX`, `regY`, and `count` properties.
	 * `width` & `height` are required and specify the dimensions of the frames.
	 * `regX` & `regY` indicate the registration point or "origin" of the frames.
	 * `spacing` indicate the spacing between frames.
	 * `margin` specify the margin around the image(s).
	 * `count` allows you to specify the total number of frames in the spritesheet; if omitted, this will be calculated
	 * based on the dimensions of the source images and the frames. Frames will be assigned indexes based on their position
	 * in the source images (left to right, top to bottom).
	 *
	 * 	frames: {width:64, height:64, count:20, regX: 32, regY:64, spacing:0, margin:0}
	 *
	 * <LI> if the frames are of different sizes, use an array of frame definitions. Each definition is itself an array
	 * with 4 required and 3 optional entries, in the order: `x`, `y`, `width`, `height`, `imageIndex`, `regX`, `regY`. The first
	 * four entries are required and define the frame rectangle. The fifth specifies the index of the source image (defaults to 0). The
	 * last two specify the registration point of the frame.
	 *
	 * 	frames: [
	 * 		// x, y, width, height, imageIndex*, regX*, regY*
	 * 		[64, 0, 96, 64],
	 * 		[0, 0, 64, 64, 1, 32, 32]
	 * 		// etc.
	 * 	]
	 *
	 * </OL>
	 *
	 * <h4>animations</h4>
	 * Optional. An object defining sequences of frames to play as named animations. Each property corresponds to an
	 * animation of the same name. Each animation must specify the frames to play, and may
	 * also include a relative playback `speed` (ex. 2 would playback at double speed, 0.5 at half), and
	 * the name of the `next` animation to sequence to after it completes.
	 *
	 * There are three formats supported for defining the frames in an animation, which can be mixed and matched as appropriate:<OL>
	 * <LI> for a single frame animation, you can simply specify the frame index
	 *
	 * 	animations: {
	 * 		sit: 7
	 * 	}
	 *
	 * <LI> for an animation of consecutive frames, you can use an array with two required, and two optional entries
	 * in the order: `start`, `end`, `next`, and `speed`. This will play the frames from start to end inclusive.
	 *
	 * 	animations: {
	 * 		// start, end, next*, speed*
	 * 		run: [0, 8],
	 * 		jump: [9, 12, "run", 2]
	 * 	}
	 *
	 * <LI> for non-consecutive frames, you can use an object with a `frames` property defining an array of frame indexes to
	 * play in order. The object can also specify `next` and `speed` properties.
	 *
	 * 	animations: {
	 * 		walk: {
	 * 			frames: [1,2,3,3,2,1]
	 * 		},
	 * 		shoot: {
	 * 			frames: [1,4,5,6],
	 * 			next: "walk",
	 * 			speed: 0.5
	 * 		}
	 * 	}
	 *
	 * </OL>
	 * <strong>Note:</strong> the `speed` property was added in EaselJS 0.7.0. Earlier versions had a `frequency`
	 * property instead, which was the inverse of `speed`. For example, a value of "4" would be 1/4 normal speed in earlier
	 * versions, but is 4x normal speed in 0.7.0+.
	 *
	 * <h4>framerate</h4>
	 * Optional. Indicates the default framerate to play this spritesheet at in frames per second.
	 * See {{#crossLink "SpriteSheet/framerate:property"}}{{/crossLink}} for more information.
	 *
	 * 	framerate: 20
	 *
	 * <h4>Example</h4>
	 * To define a simple sprite sheet, with a single image "sprites.jpg" arranged in a regular 50x50 grid with three
	 * animations: "stand" showing the first frame, "run" looping frame 1-5 inclusive, and "jump" playing  frame 6-8 and sequencing back to run.
	 *
	 * 	var data = {
	 * 		images: ["sprites.jpg"],
	 * 		frames: {width:50, height:50},
	 * 		animations: {
	 * 			stand:0,
	 * 			run:[1,5],

	/**
	 * 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 EaselJS framework by calling {{#crossLink "Graphics/draw"}}{{/crossLink}}
	 * directly, or it can be used with the {{#crossLink "Shape"}}{{/crossLink}} object to draw vector graphics within the
	 * context of an EaselJS display list.
	 *
	 * There are two approaches to working with Graphics object: calling methods on a Graphics instance (the "Graphics API"), or
	 * instantiating Graphics command objects and adding them to the graphics queue via {{#crossLink "Graphics/append"}}{{/crossLink}}.
	 * The former abstracts the latter, simplifying beginning and ending paths, fills, and strokes.
	 *
	 *      var g = new createjs.Graphics();
	 *      g.setStrokeStyle(1);
	 *      g.beginStroke("#000000");
	 *      g.beginFill("red");
	 *      g.drawCircle(0,0,30);
	 *
	 * 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:
	 *
	 *      myGraphics.beginStroke("red").beginFill("blue").drawRect(20, 20, 100, 50);
	 *
	 * Each graphics API call generates a command object (see below). The last command to be created can be accessed via
	 * {{#crossLink "Graphics/command:property"}}{{/crossLink}}:
	 *
	 *      var fillCommand = myGraphics.beginFill("red").command;
	 *      // ... later, update the fill style/color:
	 *      fillCommand.style = "blue";
	 *      // or change it to a bitmap fill:
	 *      fillCommand.bitmap(myImage);
	 *
	 * For more direct control of rendering, you can instantiate and append command objects to the graphics queue directly. In this case, you
	 * need to manage path creation manually, and ensure that fill/stroke is applied to a defined path:
	 *
	 *      // start a new path. Graphics.beginCmd is a reusable BeginPath instance:
	 *      myGraphics.append(createjs.Graphics.beginCmd);
	 *      // we need to define the path before applying the fill:
	 *      var circle = new createjs.Graphics.Circle(0,0,30);
	 *      myGraphics.append(circle);
	 *      // fill the path we just defined:
	 *      var fill = new createjs.Graphics.Fill("red");
	 *      myGraphics.append(fill);
	 *
	 * These approaches can be used together, for example to insert a custom command:
	 *
	 *      myGraphics.beginFill("red");
	 *      var customCommand = new CustomSpiralCommand(etc);
	 *      myGraphics.append(customCommand);
	 *      myGraphics.beginFill("blue");
	 *      myGraphics.drawCircle(0, 0, 30);
	 *
	 * See {{#crossLink "Graphics/append"}}{{/crossLink}} for more info on creating custom commands.
	 *
	 * <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.

	/**
	 * Decodes a compact encoded path string into a series of draw instructions.
	 * This format is not intended to be human readable, and is meant for use by authoring tools.
	 * 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

	 * 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:
	 *
	 *      var shape = new createjs.Shape();
	 *      shape.graphics.beginFill("#ff0000").drawCircle(0, 0, 25);
	 *      myShape.cache(-25, -25, 50, 50);
	 *
	 * Note that filters need to be defined <em>before</em> the cache is applied. Check out the {{#crossLink "Filter"}}{{/crossLink}}
	 * 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)
	 * will add padding to the canvas dimensions.
	 *
	 * @method cache
	 * @param {Number} x The x coordinate origin for the cache region.
	 * @param {Number} y The y coordinate origin for the cache region.
	 * @param {Number} width The width of the cache region.
	 * @param {Number} height The height of the cache region.
	 * @param {Number} [scale=1] The scale at which the cache will be created. For example, if you cache a vector shape using
	 * 	myShape.cache(0,0,100,100,2) then the resulting cacheCanvas will be 200x200 px. This lets you scale and rotate
	 * 	cached elements with greater fidelity. Default is 1.
