   * - An option `preventDefault` to stop all default browser behavior.
   *
   * Usage:
   *   var hammer = propagatingHammer(new Hammer(element));
   *   var hammer = propagatingHammer(new Hammer(element), {preventDefault: true});
   *
   * @param {Hammer.Manager} hammer   An hammer instance.
   * @param {Object} [options]        Available options:
   *                                  - `preventDefault: true | false | 'mouse' | 'touch' | 'pen'`.
   *                                    Enforce preventing the default browser behavior.
   *                                    Cannot be set to `false`.

	 * ```js

	 * var sprite1 = new PIXI.Sprite(texture);

	 *
	 * __Hint-2__: The actual memory allocation will happen on first render.
	 * You shouldn't create renderTextures each frame just to delete them after, try to reuse them.
	 *
	 * A RenderTexture takes a snapshot of any Display Object given to its render method. For example:
	 *
	 * ```js
	 * let renderer = PIXI.autoDetectRenderer();
	 * let renderTexture = PIXI.RenderTexture.create(800, 600);
	 * let sprite = PIXI.Sprite.from("spinObj_01.png");

	 * sprite.anchor.x = 0.5;
	 * sprite.anchor.y = 0.5;
	 *
	 * renderer.render(sprite, renderTexture);
	 * ```
	 *
	 * The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0
	 * you can clear the transform
	 *
	 * ```js
	 *
	 * sprite.setTransform()
	 *
	 * let renderTexture = new PIXI.RenderTexture.create(100, 100);
	 *

	 * Filter is a special type of WebGL shader that is applied to the screen.
	 *
	 * {@link http://pixijs.io/examples/#/filters/blur-filter.js Example} of the
	 * {@link PIXI.filters.BlurFilter BlurFilter}.
	 *
	 * ### Usage
	 * Filters can be applied to any DisplayObject or Container.
	 * PixiJS' `FilterSystem` renders the container into temporary Framebuffer,
	 * then filter renders it to the screen.
	 * Multiple filters can be added to the `filters` array property and stacked on each other.
	 *
	 * ```
	 * const filter = new PIXI.Filter(myShaderVert, myShaderFrag, { myUniform: 0.5 });
	 * const container = new PIXI.Container();
	 * container.filters = [filter];
	 * ```
	 *
	 * ### Previous Version Differences
	 *
	 * In PixiJS **v3**, a filter was always applied to _whole screen_.
	 *
	 * In PixiJS **v4**, a filter can be applied _only part of the screen_.
	 * Developers had to create a set of uniforms to deal with coordinates.
	 *
	 * In PixiJS **v5** combines _both approaches_.
	 * Developers can use normal coordinates of v3 and then allow filter to use partial Framebuffers,
	 * bringing those extra uniforms into account.
	 *
	 * Also be aware that we have changed default vertex shader, please consult
	 * {@link https://github.com/pixijs/pixi.js/wiki/v5-Creating-filters Wiki}.
	 *
	 * ### Built-in Uniforms
	 *
	 * PixiJS viewport uses screen (CSS) coordinates, `(0, 0, renderer.screen.width, renderer.screen.height)`,
	 * and `projectionMatrix` uniform maps it to the gl viewport.
	 *
	 * **uSampler**
	 *
	 * The most important uniform is the input texture that container was rendered into.
	 * _Important note: as with all Framebuffers in PixiJS, both input and output are
	 * premultiplied by alpha._
	 *
	 * By default, input normalized coordinates are passed to fragment shader with `vTextureCoord`.
	 * Use it to sample the input.
	 *
	 * ```
	 * const fragment = `
	 * varying vec2 vTextureCoord;
	 * uniform sampler2D uSampler;
	 * void main(void)
	 * {
	 *    gl_FragColor = texture2D(uSampler, vTextureCoord);
	 * }
	 * `;
	 *
	 * const myFilter = new PIXI.Filter(null, fragment);
	 * ```
	 *
	 * This filter is just one uniform less than {@link PIXI.filters.AlphaFilter AlphaFilter}.
	 *
	 * **outputFrame**
	 *
	 * The `outputFrame` holds the rectangle where filter is applied in screen (CSS) coordinates.
	 * It's the same as `renderer.screen` for a fullscreen filter.
	 * Only a part of  `outputFrame.zw` size of temporary Framebuffer is used,
	 * `(0, 0, outputFrame.width, outputFrame.height)`,
	 *
	 * Filters uses this quad to normalized (0-1) space, its passed into `aVertexPosition` attribute.
	 * To calculate vertex position in screen space using normalized (0-1) space:
	 *
	 * ```
	 * vec4 filterVertexPosition( void )
	 * {
	 *     vec2 position = aVertexPosition * max(outputFrame.zw, vec2(0.)) + outputFrame.xy;
	 *     return vec4((projectionMatrix * vec3(position, 1.0)).xy, 0.0, 1.0);
	 * }
	 * ```
	 *
	 * **inputSize**
	 *
	 * Temporary framebuffer is different, it can be either the size of screen, either power-of-two.
	 * The `inputSize.xy` are size of temporary framebuffer that holds input.
	 * The `inputSize.zw` is inverted, it's a shortcut to evade division inside the shader.
	 *
	 * Set `inputSize.xy = outputFrame.zw` for a fullscreen filter.
	 *
	 * To calculate input normalized coordinate, you have to map it to filter normalized space.
	 * Multiply by `outputFrame.zw` to get input coordinate.
	 * Divide by `inputSize.xy` to get input normalized coordinate.
	 *
	 * ```
	 * vec2 filterTextureCoord( void )
	 * {
	 *     return aVertexPosition * (outputFrame.zw * inputSize.zw); // same as /inputSize.xy
	 * }
	 * ```
	 * **resolution**
	 *
	 * The `resolution` is the ratio of screen (CSS) pixels to real pixels.
	 *
	 * **inputPixel**
	 *
	 * `inputPixel.xy` is the size of framebuffer in real pixels, same as `inputSize.xy * resolution`
	 * `inputPixel.zw` is inverted `inputPixel.xy`.
	 *
	 * It's handy for filters that use neighbour pixels, like {@link PIXI.filters.FXAAFilter FXAAFilter}.
	 *
	 * **inputClamp**
	 *
	 * If you try to get info from outside of used part of Framebuffer - you'll get undefined behaviour.
	 * For displacements, coordinates has to be clamped.
	 *
	 * The `inputClamp.xy` is left-top pixel center, you may ignore it, because we use left-top part of Framebuffer
	 * `inputClamp.zw` is bottom-right pixel center.
	 *
	 * ```
	 * vec4 color = texture2D(uSampler, clamp(modifigedTextureCoord, inputClamp.xy, inputClamp.zw))
	 * ```
	 * OR
	 * ```
	 * vec4 color = texture2D(uSampler, min(modifigedTextureCoord, inputClamp.zw))
	 * ```
	 *
	 * ### Additional Information
	 *
	 * Complete documentation on Filter usage is located in the
	 * {@link https://github.com/pixijs/pixi.js/wiki/v5-Creating-filters Wiki}.
	 *
	 * Since PixiJS only had a handful of built-in filters, additional filters can be downloaded
	 * {@link https://github.com/pixijs/pixi-filters here} from the PixiJS Filters repository.

	 * Other more advanced functionality like masking, children, filters, etc will not work on sprites in this batch.

	 *     let sprite = PIXI.Sprite.from("myImage.png");

	 * The primary advantage of this class over Text is that all of your textures are pre-generated and loading,

	 *
	 * The primary disadvantage is that you need to preload the bitmap font assets, and thus the styling is set in stone.

	 * You can use this filter to apply all manor of crazy warping effects.

	 * If you know a bit this should abstract enough away to make you life easier!
	 *
	 * Pretty much ALL WebGL can be broken down into the following:
	 * - Geometry - The structure and data for the mesh. This can include anything from positions, uvs, normals, colors etc..
	 * - Shader - This is the shader that PixiJS will render the geometry with (attributes in the shader must match the geometry)
	 * - State - This is the state of WebGL required to render the mesh.
	 *
	 * Through a combination of the above elements you can render anything you want, 2D or 3D!

Imagine doing a timeline.seek(0) and there's a callback that sits at 0. Since events are suppressed on that seek() by default, nothing will fire, but when the playhead moves off of that position, the callback should fire. This behavior is what people intuitively expect.

		 * @param {boolean=} clr If true, the values should be searched for color-related data. For example, boxShadow values typically contain a color whereas borderRadius don't.
		 * @param {boolean=} collapsible If true, the value is a top/left/right/bottom style one that acts like margin or padding, where if only one value is received, it's used for all 4; if 2 are received, the first is duplicated for 3rd (bottom) and the 2nd is duplicated for the 4th spot (left), etc.

			/**
			 * @private Most other plugins (like BezierPlugin and ThrowPropsPlugin and others) can only tween numeric values, but CSSPlugin must accommodate special values that have a bunch of extra data (like a suffix or strings between numeric values, etc.). For example, boxShadow has values like "10px 10px 20px 30px rgb(255,0,0)" which would utterly confuse other plugins. This method allows us to split that data apart and grab only the numeric data and attach it to uniquely-named properties of a generic proxy object ({}) so that we can feed that to virtually any plugin to have the numbers tweened. However, we must also keep track of which properties from the proxy go with which CSSPropTween values and instances. So we create a linked list of MiniPropTweens. Each one records a target (the original CSSPropTween), property (like "s" or "xn1" or "xn2") that we're tweening and the unique property name that was used for the proxy (like "boxShadow_xn1" and "boxShadow_xn2") and whether or not they need to be rounded. That way, in the _setPluginRatio() method we can simply copy the values over from the proxy to the CSSPropTween instance(s). Then, when the main CSSPlugin setRatio() method runs and applies the CSSPropTween values accordingly, they're updated nicely. So the external plugin tweens the numbers, _setPluginRatio() copies them over, and setRatio() acts normally, applying css-specific values to the element.
			 * This method returns an object that has the following properties:
			 *  - proxy: a generic object containing the starting values for all the properties that will be tweened by the external plugin.  This is what we feed to the external _onInitTween() as the target
			 *  - end: a generic object containing the ending values for all the properties that will be tweened by the external plugin. This is what we feed to the external plugin's _onInitTween() as the destination values
			 *  - firstMPT: the first MiniPropTween in the linked list
			 *  - pt: the first CSSPropTween in the linked list that was created when parsing. If shallow is true, this linked list will NOT attach to the one passed into the _parseToProxy() as the "pt" (4th) parameter.
			 * @param {!Object} t target object to be tweened
			 * @param {!(Object|string)} vars the object containing the information about the tweening values (typically the end/destination values) that should be parsed

			/**
			 * @constructor Each property that is tweened has at least one CSSPropTween associated with it. These instances store important information like the target, property, starting value, amount of change, etc. They can also optionally have a number of "extra" strings and numeric values named xs1, xn1, xs2, xn2, xs3, xn3, etc. where "s" indicates string and "n" indicates number. These can be pieced together in a complex-value tween (type:1) that has alternating types of data like a string, number, string, number, etc. For example, boxShadow could be "5px 5px 8px rgb(102, 102, 51)". In that value, there are 6 numbers that may need to tween and then pieced back together into a string again with spaces, suffixes, etc. xs0 is special in that it stores the suffix for standard (type:0) tweens, -OR- the first string (prefix) in a complex-value (type:1) CSSPropTween -OR- it can be the non-tweening value in a type:-1 CSSPropTween. We do this to conserve memory.
			 * CSSPropTweens have the following optional properties as well (not defined through the constructor):
			 *  - l: Length in terms of the number of extra properties that the CSSPropTween has (default: 0). For example, for a boxShadow we may need to tween 5 numbers in which case l would be 5; Keep in mind that the start/end values for the first number that's tweened are always stored in the s and c properties to conserve memory. All additional values thereafter are stored in xn1, xn2, etc.
			 *  - xfirst: The first instance of any sub-CSSPropTweens that are tweening properties of this instance. For example, we may split up a boxShadow tween so that there's a main CSSPropTween of type:1 that has various xs* and xn* values associated with the h-shadow, v-shadow, blur, color, etc. Then we spawn a CSSPropTween for each of those that has a higher priority and runs BEFORE the main CSSPropTween so that the values are all set by the time it needs to re-assemble them. The xfirst gives us an easy way to identify the first one in that chain which typically ends at the main one (because they're all prepende to the linked list)
			 *  - plugin: The TweenPlugin instance that will handle the tweening of any complex values. For example, sometimes we don't want to use normal subtweens (like xfirst refers to) to tween the values - we might want ThrowPropsPlugin or BezierPlugin some other plugin to do the actual tweening, so we create a plugin instance and store a reference here. We need this reference so that if we get a request to round values or disable a tween, we can pass along that request.
			 *  - data: Arbitrary data that needs to be stored with the CSSPropTween. Typically if we're going to have a plugin handle the tweening of a complex-value tween, we create a generic object that stores the END values that we're tweening to and the CSSPropTween's xs1, xs2, etc. have the starting values. We store that object as data. That way, we can simply pass that object to the plugin and use the CSSPropTween as the target.
			 *  - setRatio: Only used for type:2 tweens that require custom functionality. In this case, we call the CSSPropTween's setRatio() method and pass the ratio each time the tween updates. This isn't quite as efficient as doing things directly in the CSSPlugin's setRatio() method, but it's very convenient and flexible.
			 * @param {!Object} t Target object whose property will be tweened. Often a DOM element, but not always. It could be anything.
			 * @param {string} p Property to tween (name). For example, to tween element.width, p would be "width".
			 * @param {number} s Starting numeric value
			 * @param {number} c Change in numeric value over the course of the entire tween. For example, if element.width starts at 5 and should end at 100, c would be 95.
			 * @param {CSSPropTween=} next The next CSSPropTween in the linked list. If one is defined, we will define its _prev as the new instance, and the new instance's _next will be pointed at it.
			 * @param {number=} type The type of CSSPropTween where -1 = a non-tweening value, 0 = a standard simple tween, 1 = a complex value (like one that has multiple numbers in a comma- or space-delimited string like border:"1px solid red"), and 2 = one that uses a custom setRatio function that does all of the work of applying the values on each update.
			 * @param {string=} n Name of the property that should be used for overwriting purposes which is typically the same as p but not always. For example, we may need to create a subtween for the 2nd part of a "clip:rect(...)" tween in which case "p" might be xs1 but "n" is still "clip"
			 * @param {boolean=} r If true, the value(s) should be rounded
			 * @param {number=} pr Priority in the linked list order. Higher priority CSSPropTweens will be updated before lower priority ones. The default priority is 0.
			 * @param {string=} b Beginning value. We store this to ensure that it is EXACTLY what it was when the tween began without any risk of interpretation issues.
			 * @param {string=} e Ending value. We store this to ensure that it is EXACTLY what the user defined at the end of the tween without any risk of interpretation issues.

		/**
		 * @constructor A SpecialProp is basically a css property that needs to be treated in a non-standard way, like if it may contain a complex value like boxShadow:"5px 10px 15px rgb(255, 102, 51)" or if it is associated with another plugin like ThrowPropsPlugin or BezierPlugin. Every SpecialProp is associated with a particular property name like "boxShadow" or "throwProps" or "bezier" and it will intercept those values in the vars object that's passed to the CSSPlugin and handle them accordingly.
		 * @param {!string} p Property name (like "boxShadow" or "throwProps")
		 * @param {Object=} options An object containing any of the following configuration options:
		 *                      - defaultValue: the default value
		 *                      - parser: A function that should be called when the associated property name is found in the vars. This function should return a CSSPropTween instance and it should ensure that it is properly inserted into the linked list. It will receive 4 paramters: 1) The target, 2) The value defined in the vars, 3) The CSSPlugin instance (whose _firstPT should be used for the linked list), and 4) A computed style object if one was calculated (this is a speed optimization that allows retrieval of starting values quicker)
		 *                      - formatter: a function that formats any value received for this special property (for example, boxShadow could take "5px 5px red" and format it to "5px 5px 0px 0px red" so that both the beginning and ending values have a common order and quantity of values.)
		 *                      - prefix: if true, we'll determine whether or not this property requires a vendor prefix (like Webkit or Moz or ms or O)
		 *                      - color: set this to true if the value for this SpecialProp may contain color-related values like rgb(), rgba(), etc.
		 *                      - priority: priority in the linked list order. Higher priority SpecialProps will be updated before lower priority ones. The default priority is 0.
		 *                      - multi: if true, the formatter should accommodate a comma-delimited list of values, like boxShadow could have multiple boxShadows listed out.
		 *                      - collapsible: if true, the formatter should treat the value like it's a top/right/bottom/left value that could be collapsed, like "5px" would apply to all, "5px, 10px" would use 5px for top/bottom and 10px for right/left, etc.
		 *                      - keyword: a special keyword that can [optionally] be found inside the value (like "inset" for boxShadow). This allows us to validate beginning/ending values to make sure they match (if the keyword is found in one, it'll be added to the other for consistency by default).

		 * Registers a special property that should be intercepted from any "css" objects defined in tweens. This allows you to handle them however you want without CSSPlugin doing it for you. The 2nd parameter should be a function that accepts 3 parameters:

		 *  2) The end/destination value (could be a string, number, object, or whatever you want)
		 *  3) The tween instance (you probably don't need to worry about this, but it can be useful for looking up information like the duration)
		 *
		 * Then, your function should return a function which will be called each time the tween gets rendered, passing a numeric "ratio" parameter to your function that indicates the change factor (usually between 0 and 1). For example:
		 *
		 * CSSPlugin.registerSpecialProp("myCustomProp", function(target, value, tween) {
		 *      var start = target.style.width;
		 *      return function(ratio) {
		 *              target.style.width = (start + value * ratio) + "px";
		 *              console.log("set width to " + target.style.width);
		 *          }
		 * }, 0);
		 *
		 * Then, when I do this tween, it will trigger my special property:
		 *
		 * TweenLite.to(element, 1, {css:{myCustomProp:100}});
		 *
		 * In the example, of course, we're just changing the width, but you can do anything you want.
		 *
		 * @param {!string} name Property name (or comma-delimited list of property names) that should be intercepted and handled by your function. For example, if I define "myCustomProp", then it would handle that portion of the following tween: TweenLite.to(element, 1, {css:{myCustomProp:100}})
		 * @param {!function(Object, Object, Object, string):function(number)} onInitTween The function that will be called when a tween of this special property is performed. The function will receive 4 parameters: 1) Target object that should be tweened, 2) Value that was passed to the tween, 3) The tween instance itself (rarely used), and 4) The property name that's being tweened. Your function should return a function that should be called on every update of the tween. That function will receive a single parameter that is a "change factor" value (typically between 0 and 1) indicating the amount of change as a ratio. You can use this to determine how to set the values appropriately in your function.
		 * @param {number=} priority Priority that helps the engine determine the order in which to set the properties (default: 0). Higher priority properties will be updated before lower priority ones.

		 * tweens (so that you can easily add() them to a TimelineLite, for example). The reason this functionality is
		 * wrapped into a separate static method of CSSPlugin instead of being integrated into all regular className tweens
		 * is because it creates entirely new tweens that may have completely different targets than the original tween,
		 * so if they were all lumped into the original tween instance, it would be inconsistent with the rest of the API
		 * and it would create other problems. For example:
		 *  - If I create a tween of elementA, that tween instance may suddenly change its target to include 50 other elements (unintuitive if I specifically defined the target I wanted)
		 *  - We can't just create new independent tweens because otherwise, what happens if the original/parent tween is reversed or pause or dropped into a TimelineLite for tight control? You'd expect that tween's behavior to affect all the others.
		 *  - Analyzing every style property of every child before and after the tween is an expensive operation when there are many children, so this behavior shouldn't be imposed on all className tweens by default, especially since it's probably rare that this extra functionality is needed.
		 *
		 * @param {Object} target object to be tweened
		 * @param {number} Duration in seconds (or frames for frames-based tweens)
		 * @param {Object} Object containing the end values, like {className:"newClass", ease:Linear.easeNone}
		 * @return {Array} An array of TweenLite instances

			/**
			 * @constructor
			 * Defines a GreenSock class, optionally with an array of dependencies that must be instantiated first and passed into the definition.
			 * This allows users to load GreenSock JS files in any order even if they have interdependencies (like CSSPlugin extends TweenPlugin which is
			 * inside TweenLite.js, but if CSSPlugin is loaded first, it should wait to run its code until TweenLite.js loads and instantiates TweenPlugin
			 * and then pass TweenPlugin to CSSPlugin's definition). This is all done automatically and internally.
			 *
			 * Every definition will be added to a "com.greensock" global object (typically window, but if a window.GreenSockGlobals object is found,
			 * it will go there as of v1.7). For example, TweenLite will be found at window.com.greensock.TweenLite and since it's a global class that should be available anywhere,
			 * it is ALSO referenced at window.TweenLite. However some classes aren't considered global, like the base com.greensock.core.Animation class, so
			 * those will only be at the package like window.com.greensock.core.Animation. Again, if you define a GreenSockGlobals object on the window, everything
			 * gets tucked neatly inside there instead of on the window directly. This allows you to do advanced things like load multiple versions of GreenSock
			 * files and put them into distinct objects (imagine a banner ad uses a newer version but the main site uses an older one). In that case, you could
			 * sandbox the banner one like:
			 *
			 * <script>
			 *     var gs = window.GreenSockGlobals = {}; //the newer version we're about to load could now be referenced in a "gs" object, like gs.TweenLite.to(...). Use whatever alias you want as long as it's unique, "gs" or "banner" or whatever.
			 * </script>
			 * <script src="js/greensock/v1.7/TweenMax.js"></script>
			 * <script>
			 *     window.GreenSockGlobals = window._gsQueue = window._gsDefine = null; //reset it back to null (along with the special _gsQueue variable) so that the next load of TweenMax affects the window and we can reference things directly like TweenLite.to(...)
			 * </script>
			 * <script src="js/greensock/v1.6/TweenMax.js"></script>
			 * <script>
			 *     gs.TweenLite.to(...); //would use v1.7
			 *     TweenLite.to(...); //would use v1.6
			 * </script>
			 *
			 * @param {!string} ns The namespace of the class definition, leaving off "com.greensock." as that's assumed. For example, "TweenLite" or "plugins.CSSPlugin" or "easing.Back".
			 * @param {!Array.<string>} dependencies An array of dependencies (described as their namespaces minus "com.greensock." prefix). For example ["TweenLite","plugins.TweenPlugin","core.Animation"]
			 * @param {!function():Object} func The function that should be called and passed the resolved dependencies which will return the actual class for this definition.
			 * @param {boolean=} global If true, the class will be added to the global scope (typically window unless you define a window.GreenSockGlobals object)

If events are NOT suppressed, obviously the callback would be triggered in this render. Basically, the callback should fire either when the playhead ARRIVES or LEAVES this exact spot, not both. Imagine doing a timeline.seek(0) and there's a callback that sits at 0. Since events are suppressed on that seek() by default, nothing will fire, but when the playhead moves off of that position, the callback should fire. This behavior is what people intuitively expect. We set the _rawPrevTime to be a precise tiny number to indicate this scenario rather than using another property/variable which would increase memory usage. This technique is less readable, but more efficient.

Imagine obj.x starts at 0 and then we do tl.set(obj, {x:100}).to(obj, 1, {x:200}) and then later we tl.reverse()...the goal is to have obj.x revert to 0.
