/**
* 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.
*
* <b>Browser support</b>
* The event model in CreateJS can be used separately from the suite in any project, however the inheritance model
* requires modern browsers (IE9+).

* A shortcut method for using addEventListener that makes it easier to specify an execution scope, have a listener
* only run once, associate arbitrary data with the listener, and remove the listener.
*
* This method works by creating an anonymous wrapper function and subscribing it with addEventListener.
* The wrapper function is returned for use with `removeEventListener` (or `off`).
*
* <b>IMPORTANT:</b> To remove a listener added with `on`, you must pass in the returned wrapper function as the listener, or use
* {{#crossLink "Event/remove"}}{{/crossLink}}. Likewise, each time you call `on` a NEW wrapper function is subscribed, so multiple calls
* to `on` with the same params will create multiple listeners.
*
* <h4>Example</h4>
*
* var listener = myBtn.on("click", handleClick, null, false, {count:3});
* function handleClick(evt, data) {
* data.count -= 1;
* console.log(this == myBtn); // true - scope defaults to the dispatcher
* if (data.count == 0) {
* alert("clicked 3 times!");
* myBtn.off("click", listener);
* // alternately: evt.remove();
* }
* }
*
* @method on
* @param {String} type The string type of the event.
* @param {Function | Object} listener An object with a handleEvent method, or a function that will be called when
* the event is dispatched.
* @param {Object} [scope] The scope to execute the listener in. Defaults to the dispatcher/currentTarget for function listeners, and to the listener itself for object listeners (ie. using handleEvent).
* @param {Boolean} [once=false] If true, the listener will remove itself after the first time it is triggered.
* @param {*} [data] Arbitrary data that will be included as the second parameter when the listener is called.
* @param {Boolean} [useCapture=false] For events that bubble, indicates whether to listen for the event in the capture or bubbling/target phase.
* @return {Function} Returns the anonymous function that was created and assigned as the listener. This is needed to remove the listener later using .removeEventListener.

* 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:
* When all of the frames are the same size (in a grid), use an object with `width`, `height`, `regX`, `regY`,
* and `count` properties.
*
* <ul>
* <li>`width` & `height` are required and specify the dimensions of the frames</li>
* <li>`regX` & `regY` indicate the registration point or "origin" of the frames</li>
* <li>`spacing` indicate the spacing between frames</li>
* <li>`margin` specify the margin around the image(s)</li>
* <li>`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).</li>
* </ul>
*
* frames: {width:64, height:64, count:20, regX: 32, regY:64, spacing:0, margin:0}
*
* 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:
*
* <ul>
* <li>The first four, `x`, `y`, `width`, and `height` are required and define the frame rectangle.</li>
* <li>The fifth, `imageIndex`, specifies the index of the source image (defaults to 0)</li>
* <li>The last two, `regX` and `regY` specify the registration point of the frame</li>
* </ul>
*
* frames: [
* // x, y, width, height, imageIndex*, regX*, regY*
* [64, 0, 96, 64],
* [0, 0, 64, 64, 1, 32, 32]
* // etc.
* ]
*
* <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>
* <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>
* <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
* }
* }
*
* </li>
* </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 EaselJS 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
*
* Note that the Sprite framerate will only work if the stage update method is provided with the {{#crossLink "Ticker/tick:event"}}{{/crossLink}}
* event generated by the {{#crossLink "Ticker"}}{{/crossLink}}.
*
* createjs.Ticker.on("tick", handleTick);
* function handleTick(event) {
* stage.update(event);
* }
*
* <h3>Example</h3>
* 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],
* jump:[6,8,"run"]
* }
* };
* var spriteSheet = new createjs.SpriteSheet(data);
* var animation = new createjs.Sprite(spriteSheet, "run");
*
* <h3>Generating SpriteSheet Images</h3>
* Spritesheets can be created manually by combining images in PhotoShop, and specifying the frame size or
* coordinates manually, however there are a number of tools that facilitate this.
* <ul>
* <li>Exporting SpriteSheets or HTML5 content from Flash Pro supports the EaselJS SpriteSheet format.</li>
* <li>The popular <a href="https://www.codeandweb.com/texturepacker/easeljs" target="_blank">Texture Packer</a> has
* EaselJS support.
* <li>SWF animations in Flash can be exported to SpriteSheets using <a href="http://createjs.com/zoe" target="_blank"></a></li>
* </ul>
*
* <h3>Cross Origin Issues</h3>
* <strong>Warning:</strong> Images loaded cross-origin will throw cross-origin security errors when interacted with
* using:
* <ul>
* <li>a mouse</li>
* <li>methods such as {{#crossLink "Container/getObjectUnderPoint"}}{{/crossLink}}</li>
* <li>Filters (see {{#crossLink "Filter"}}{{/crossLink}})</li>
* <li>caching (see {{#crossLink "DisplayObject/cache"}}{{/crossLink}})</li>
* </ul>
* You can get around this by setting `crossOrigin` property on your images before passing them to EaselJS, or
* setting the `crossOrigin` property on PreloadJS' LoadQueue or LoadItems.
*
* var image = new Image();
* img.crossOrigin="Anonymous";
* img.src = "http://server-with-CORS-support.com/path/to/image.jpg";
*
* If you pass string paths to SpriteSheets, they will not work cross-origin. The server that stores the image must
* support cross-origin requests, or this will not work. For more information, check out
* <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS" target="_blank">CORS overview on MDN</a>.

/**
* 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
* provide an absolute position of +150.0px.
* <br />AAA - 000000000000000000. A y delta value of 0.

* To disable relaying, set nextStage to null.
*
* MouseOver, MouseOut, RollOver, and RollOut interactions are also passed through using the mouse over settings
* of the top-most stage, but are only processed if the target stage has mouse over interactions enabled.
* Considerations when using roll over in relay targets:<OL>
* <LI> The top-most (first) stage must have mouse over interactions enabled (via enableMouseOver)</LI>
* <LI> All stages that wish to participate in mouse over interaction must enable them via enableMouseOver</LI>
* <LI> All relay targets will share the frequency value of the top-most stage</LI>
* </OL>
* To illustrate, in this example the targetStage would process mouse over interactions at 10hz (despite passing
* 30 as it's desired frequency):
* topStage.nextStage = targetStage;
* topStage.enableMouseOver(10);
* targetStage.enableMouseOver(30);
*
* If the target stage's canvas is completely covered by this stage's canvas, you may also want to disable its
* DOM events using:
*
* targetStage.enableDOMEvents(false);

* the animation using {{#crossLink "MovieClip/gotoAndPlay"}}{{/crossLink}}.
*
* var stage = new createjs.Stage("canvas");

* not rendered to canvas, and as such will retain whatever z-index it has relative to the canvas (ie. it will be
