	/**
	 * 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.

	 *          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.
	 *

// constructor:
	/**
	 * 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:
	 * 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 Adobe Flash/Animate 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 Adobe Flash/Animate can be exported to SpriteSheets using <a href="http://createjs.com/zoe" target="_blank">Zo&euml;</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.

	 *
	 * 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

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

	 * 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> again. You must specify the cached 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);

	 * 
	 * Usually, the resulting cacheCanvas will have the dimensions width * scale, height * scale, however some filters (ex. BlurFilter)
	 * will add padding to the canvas dimensions.
	 *
	 * In previous versions caching was handled on DisplayObject but has since been moved to {{#crossLink "BitmapCache"}}{{/crossLink}}.

 * README IF EDITING:
 * Terminology for developers:
 *
 * Vertex: a point that help defines a shape, 3 per triangle. Usually has an x,y,z but can have more/less info.
 * Vertex Property: a piece of information attached to the vertex like a vector3 containing x,y,z
 * Index/Indices: used in groups of 3 to define a triangle, points to vertices by their index in an array (some render
 * 		modes do not use these)
 * Card: a group of 2 triangles used to display a rectangular image
 * U/V: common names for the [0-1] texture co-ordinates on an image
 * Batch: a single call to the renderer, best done as little as possible so multiple cards are put into a single batch
 * Buffer: WebGL array data
 * Program/Shader: For every vertex we run the Vertex shader. The results are used per pixel by the Fragment shader. When
 * 		combined and paired these are a shader "program"
 * Texture: WebGL representation of image data and associated extra information
 * Slot: A space on the GPU into which textures can be loaded for use in a batch, using "ActiveTexture" switches texture slot.

	/**
	 * A StageGL instance is the root level {{#crossLink "Container"}}{{/crossLink}} for an WebGL-optimized display list,
	 * which is used in place of the usual {{#crossLink "Stage"}}{{/crossLink}}. This class should behave identically to
	 * a {{#crossLink "Stage"}}{{/crossLink}} except for WebGL-specific functionality.
	 *
	 * Each time the {{#crossLink "Stage/tick"}}{{/crossLink}} method is called, the display list is rendered to the
	 * target &lt;canvas/&gt; instance, ignoring non-WebGL-compatible display objects. On devices and browsers that don't
	 * support WebGL, content will automatically be rendered to canvas 2D context instead.
	 *
	 * <h4>Limitations</h4>
	 * - {{#crossLink "Shape"}}{{/crossLink}}, {{#crossLink "Shadow"}}{{/crossLink}}, and {{#crossLink "Text"}}{{/crossLink}}
	 * 	are not rendered when added to the display list.
	 * - To display something StageGL cannot render, {{#crossLink "displayObject/cache"}}{{/crossLink}} the object.
	 *	Caches can be rendered regardless of source.
	 * - Images are wrapped as a webGL "Texture". Each graphics card has a limit to its concurrent Textures, too many 
	 * Textures will noticeably slow performance.
	 * - Each cache counts as an individual Texture. As such {{#crossLink "SpriteSheet"}}{{/crossLink}} and 
	 * {{#crossLink "SpriteSheetBuilder"}}{{/crossLink}} are recommended practices to help keep texture counts low.
	 * - To use any image node (DOM Image/Canvas Element) between multiple StageGL instances it must be a 
	 * {{#crossLink "Bitmap/clone"}}{{/crossLink}}, otherwise the GPU texture loading and tracking will get confused.
	 * - to avoid an up/down scaled render you must call {{#crossLink "StageGL/updateViewport"}}{{/crossLink}} if you
	 * resize your canvas after making a StageGL instance, this will properly size the WebGL context stored in memory.
	 * - Best performance in demanding scenarios will come from manual management of texture memory, but it is handled
	 * automatically by default. See {{#crossLink "StageGL/releaseTexture"}}{{/crossLink}} for details.
	 *
	 * <h4>Example</h4>
	 * This example creates a StageGL instance, adds a child to it, then uses the EaselJS {{#crossLink "Ticker"}}{{/crossLink}}
	 * to update the child and redraw the stage.
	 *
	 *      var stage = new createjs.StageGL("canvasElementId");
	 *
	 *      var image = new createjs.Bitmap("imagePath.png");
	 *      stage.addChild(image);
	 *
	 *      createjs.Ticker.on("tick", handleTick);
	 *
	 *      function handleTick(event) {
	 *          image.x += 10;
	 *          stage.update();
	 *      }
	 *
	 * <h4>Notes</h4>
	 * - StageGL is not currently included in the minified version of EaselJS.
	 * - {{#crossLink "SpriteContainer"}}{{/crossLink}} (the previous approach to WebGL with EaselJS) has been deprecated.
	 * - Earlier versions of WebGL support in EaselJS (SpriteStage and SpriteContainer) had hard limitations on images
	 * 	per container, which have been solved.

	 * @class StageGL
	 * @extends Stage

	 * @param {HTMLCanvasElement | String | Object} canvas A canvas object that StageGL will render to, or the string id

	 * @param {Boolean} [options.preserveBuffer=false] If `true`, the canvas is NOT auto-cleared by WebGL (the spec
	 *  discourages setting this to `true`). This is useful if you want persistent draw effects.
	 * @param {Boolean} [options.antialias=false] Specifies whether or not the browser's WebGL implementation should try

	 * @param {Boolean} [options.transparent=false] If `true`, the canvas is transparent. This is <strong>very</strong>
	 * expensive, and should be used with caution.
	 * @param {Boolean} [options.premultiply=false] Alters color handling. If `true`, this assumes the shader must

	 * problems with other assets.

	 * <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);
	 *      domElement.htmlElement.onclick = function() {
	 *          console.log("clicked");
	 *      }
	 *
	 * <strong>Important:</strong> This class needs to be notified it is about to be drawn, this will happen automatically
	 * if you call stage.update, calling stage.draw or disabling tickEnabled will miss important steps and it will render
	 * stale information.

	 * by the {{#crossLink "DisplayObject/cache"}}{{/crossLink}} function and this class description. Here are the detailed
	 * specifics of how to use the options object.
	 *
	 * - If options.useGL is set to "new" a StageGL is created and contained on this for use when rendering the cache.
	 * - If options.useGL is set to "stage" if the current stage is a StageGL it will be used. If not then it will default to "new".
	 * - If options.useGL is a StageGL instance it will not create one but use the one provided.
	 * - If options.useGL is undefined a Context 2D cache will be performed.
	 *
	 * This means you can use any combination of StageGL and 2D with either, neither, or both the stage and cache being
	 * WebGL. Using "new" with a StageGL display list is highly unrecommended, but still an option. It should be avoided
	 * due to negative performance reasons and the Image loading limitation noted in the class complications above.
	 *
	 * When "options.useGL" is set to the parent stage of the target and WebGL, performance is increased by using
	 * "RenderTextures" instead of canvas elements. These are internal Textures on the graphics card stored in the GPU.
	 * Because they are no longer canvases you cannot perform operations you could with a regular canvas. The benefit
	 * is that this avoids the slowdown of copying the texture back and forth from the GPU to a Canvas element.
	 * This means "stage" is the recommended option when available.
	 *
	 * A StageGL cache does not infer the ability to draw objects a StageGL cannot currently draw, i.e. do not use a
	 * WebGL context cache when caching a Shape, Text, etc.
	 * <h4>WebGL cache with a 2D context</h4>
	 *
	 *     var stage = new createjs.Stage();
	 *     var bmp = new createjs.Bitmap(src);
	 *     bmp.cache(0, 0, bmp.width, bmp.height, 1, {gl: "new"});          // no StageGL to use, so make one
	 *
	 *     var shape = new createjs.Shape();
	 *     shape.graphics.clear().fill("red").drawRect(0,0,20,20);
	 *     shape.cache(0, 0, 20, 20, 1);                             // cannot use WebGL cache
	 *
	 * <h4>WebGL cache with a WebGL context</h4>
	 *
	 *     var stageGL = new createjs.StageGL();
	 *     var bmp = new createjs.Bitmap(src);
	 *     bmp.cache(0, 0, bmp.width, bmp.height, 1, {gl: "stage"});       // use our StageGL to cache
	 *
	 *     var shape = new createjs.Shape();
	 *     shape.graphics.clear().fill("red").drawRect(0,0,20,20);
	 *     shape.cache(0, 0, 20, 20, 1);                             // cannot use WebGL cache
	 *
	 * You may wish to create your own StageGL instance to control factors like clear color, transparency, AA, and
	 * others. If you do, pass a new instance in instead of "true", the library will automatically set the
	 * {{#crossLink "StageGL/isCacheControlled"}}{{/crossLink}} to true on your instance. This will trigger it to behave
