/**
* AnimationBuilder is an injectable service that is available when the {@link
* BrowserAnimationsModule BrowserAnimationsModule} or {@link NoopAnimationsModule
* NoopAnimationsModule} modules are used within an application.
*
* The purpose if this service is to produce an animation sequence programmatically within an
* angular component or directive.
*
* Programmatic animations are first built and then a player is created when the build animation is
* attached to an element.
*
* ```ts
* // remember to include the BrowserAnimationsModule module for this to work...
* import {AnimationBuilder} from '@angular/animations';
*
* class MyCmp {
* constructor(private _builder: AnimationBuilder) {}
*
* makeAnimation(element: any) {
* // first build the animation
* const myAnimation = this._builder.build([
* style({ width: 0 }),
* animate(1000, style({ width: '100px' }))
* ]);
*
* // then create a player from it
* const player = myAnimation.create(element);
*
* player.play();
* }
* }
* ```
*
* When an animation is built an instance of {@link AnimationFactory AnimationFactory} will be
* returned. Using that an {@link AnimationPlayer AnimationPlayer} can be created which can then be
* used to start the animation.
*
* @experimental Animation support is experimental.
*/

function AnimationBuilder() {
}
return AnimationBuilder;

* AnimationBuilder.build}.

* `trigger` is an animation-specific function that is designed to be used inside of Angular's
* animation DSL language. If this information is new, please navigate to the
* {@link Component#animations component animations metadata page} to gain a better
* understanding of how animations in Angular are used.
*
* `trigger` Creates an animation trigger which will a list of {@link state state} and
* {@link transition transition} entries that will be evaluated when the expression
* bound to the trigger changes.
*
* Triggers are registered within the component annotation data under the
* {@link Component#animations animations section}. An animation trigger can be placed on an element
* within a template by referencing the name of the trigger followed by the expression value that
the
* trigger is bound to (in the form of `[@triggerName]="expression"`.
*
* Animation trigger bindings strigify values and then match the previous and current values against
* any linked transitions. If a boolean value is provided into the trigger binding then it will both
* be represented as `1` or `true` and `0` or `false` for a true and false boolean values
* respectively.
*
* ### Usage
*
* `trigger` will create an animation trigger reference based on the provided `name` value. The
* provided `animation` value is expected to be an array consisting of {@link state state} and
* {@link transition transition} declarations.
*
* ```typescript
* @Component({
* selector: 'my-component',
* templateUrl: 'my-component-tpl.html',
* animations: [
* trigger("myAnimationTrigger", [
* state(...),
* state(...),
* transition(...),
* transition(...)
* ])
* ]
* })
* class MyComponent {
* myStatusExp = "something";
* }
* ```
*
* The template associated with this component will make use of the `myAnimationTrigger` animation
trigger by binding to an element within its template code.
*
* ```html
*
*
...
* ```
*
* ### Using an inline function
* The `transition` animation method also supports reading an inline function which can decide
* if its associated animation should be run.
*
* ```
* // this method will be run each time the `myAnimationTrigger`
* // trigger value changes...
* function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:
string]: any}): boolean {
* // notice that `element` and `params` are also available here
* return toState == 'yes-please-animate';
* }
*
* @Component({
* selector: 'my-component',
* templateUrl: 'my-component-tpl.html',
* animations: [
* trigger('myAnimationTrigger', [
* transition(myInlineMatcherFn, [
* // the animation sequence code
* ]),
* ])
* ]
* })
* class MyComponent {
* myStatusExp = "yes-please-animate";
* }
* ```
*
* The inline method will be run each time the trigger
* value changes
*
* ## Disable Animations
* A special animation control binding called `@.disabled` can be placed on an element which will
then disable animations for any inner animation triggers situated within the element as well as
any animations on the element itself.
*
* When true, the `@.disabled` binding will prevent all animations from rendering. The example
below shows how to use this feature:
*
* ```ts
* @Component({
* selector: 'my-component',
* template: `
*
*
*
* `,
* animations: [
* trigger("childAnimation", [
* // ...
* ])
* ]
* })
* class MyComponent {
* isDisabled = true;
* exp = '...';
* }
* ```
*
* The `@childAnimation` trigger will not animate because `@.disabled` prevents it from happening
(when true).
*
* Note that `@.disabled` will only disable all animations (this means any animations running on
* the same element will also be disabled).
*
* ### Disabling Animations Application-wide
* When an area of the template is set to have animations disabled, **all** inner components will
also have their animations disabled as well. This means that all animations for an angular
application can be disabled by placing a host binding set on `@.disabled` on the topmost Angular
component.
*
* ```ts
* import {Component, HostBinding} from '@angular/core';
*
* @Component({
* selector: 'app-component',
* templateUrl: 'app.component.html',
* })
* class AppComponent {
* @HostBinding('@.disabled')
* public animationsDisabled = true;
* }
* ```
*
* ### What about animations that us `query()` and `animateChild()`?
* Despite inner animations being disabled, a parent animation can {@link query query} for inner
elements located in disabled areas of the template and still animate them as it sees fit. This is
also the case for when a sub animation is queried by a parent and then later animated using {@link
animateChild animateChild}.
* ### Detecting when an animation is disabled
* If a region of the DOM (or the entire application) has its animations disabled, then animation
* trigger callbacks will still fire just as normal (only for zero seconds).
*
* When a trigger callback fires it will provide an instance of an {@link AnimationEvent}. If
animations
* are disabled then the `.disabled` flag on the event will be true.
*
* @experimental Animation support is experimental.

* animation DSL language. If this information is new, please navigate to the {@link
* Component#animations component animations metadata page} to gain a better understanding of
* how animations in Angular are used.
*
* `animate` specifies an animation step that will apply the provided `styles` data for a given
* amount of time based on the provided `timing` expression value. Calls to `animate` are expected
* to be used within {@link sequence an animation sequence}, {@link group group}, or {@link
* transition transition}.
*
* ### Usage
*
* The `animate` function accepts two input parameters: `timing` and `styles`:
*
* - `timing` is a string based value that can be a combination of a duration with optional delay
* and easing values. The format for the expression breaks down to `duration delay easing`
* (therefore a value such as `1s 100ms ease-out` will be parse itself into `duration=1000,
* delay=100, easing=ease-out`. If a numeric value is provided then that will be used as the
* `duration` value in millisecond form.
* - `styles` is the style input data which can either be a call to {@link style style} or {@link
* keyframes keyframes}. If left empty then the styles from the destination state will be collected
* and used (this is useful when describing an animation step that will complete an animation by
* {@link transition#the-final-animate-call animating to the final state}).
*
* ```typescript
* // various functions for specifying timing data
* animate(500, style(...))
* animate("1s", style(...))
* animate("100ms 0.5s", style(...))
* animate("5s ease", style(...))
* animate("5s 10ms cubic-bezier(.17,.67,.88,.1)", style(...))
*
* // either style() of keyframes() can be used
* animate(500, style({ background: "red" }))
* animate(500, keyframes([
* style({ background: "blue" })),
* style({ background: "red" }))
* ])

*
* `group` specifies a list of animation steps that are all run in parallel. Grouped animations are
* useful when a series of styles must be animated/closed off at different starting/ending times.
*
* The `group` function can either be used within a {@link sequence sequence} or a {@link transition
* transition} and it will only continue to the next instruction once all of the inner animation
* steps have completed.
*
* ### Usage
*
* The `steps` data that is passed into the `group` animation function can either consist of {@link
* style style} or {@link animate animate} function calls. Each call to `style()` or `animate()`
* within a group will be executed instantly (use {@link keyframes keyframes} or a {@link
* animate#usage animate() with a delay value} to offset styles to be applied at a later time).

*
* `sequence` Specifies a list of animation steps that are run one by one. (`sequence` is used by
* default when an array is passed as animation data into {@link transition transition}.)
*
* The `sequence` function can either be used within a {@link group group} or a {@link transition

*
* To perform animation styling in parallel with other animation steps then have a look at the

*
* ### Usage

*
* `style` declares a key/value object containing CSS properties/styles that can then be used for
* {@link state animation states}, within an {@link sequence animation sequence}, or as styling data
* for both {@link animate animate} and {@link keyframes keyframes}.
*
* ### Usage
*
* `style` takes in a key/value string map as data and expects one or more CSS property/value pairs
* to be defined.
*
* ```typescript
* // string values are used for css properties
* style({ background: "red", color: "blue" })

*
* When an asterix (`*`) character is used as a value then it will be detected from the element
* being animated and applied as animation data when the animation starts.
*
* This feature proves useful for a state depending on layout and/or environment factors; in such
* cases the styles are calculated just before the animation starts.
*
* ```typescript
* // the steps below will animate from 0 to the

*
* `state` declares an animation state within the given trigger. When a state is active within a
* component then its associated styles will persist on the element that the trigger is attached to
* (even when the animation ends).
*
* To animate between states, have a look at the animation {@link transition transition} DSL
* function. To register states to an animation trigger please have a look at the {@link trigger
* trigger} function.
*
* #### The `void` state
*
* The `void` state value is a reserved word that angular uses to determine when the element is not
* apart of the application anymore (e.g. when an `ngIf` evaluates to false then the state of the
* associated element is void).
*
* #### The `*` (default) state
*
* The `*` state (when styled) is a fallback state that will be used if the state that is being
* animated is not declared within the trigger.
*
* ### Usage
*
* `state` will declare an animation state with its associated styles
* within the given trigger.
*
* - `stateNameExpr` can be one or more state names separated by commas.
* - `styles` refers to the {@link style styling data} that will be persisted on the element once
* the state has been reached.

* // the state in which an element is detached from from the application.

*
* // user-defined states

*
* `keyframes` specifies a collection of {@link style style} entries each optionally characterized
* by an `offset` value.
*
* ### Usage
*
* The `keyframes` animation function is designed to be used alongside the {@link animate animate}
* animation function. Instead of applying animations from where they are currently to their
* destination, keyframes can describe how each style entry is applied and at what point within the
* animation arc (much like CSS Keyframe Animations do).
*
* For each `style()` entry an `offset` value can be set. Doing so allows to specify at what
* percentage of the animate time the styles will be applied.
*
* ```typescript
* // the provided offset values describe when each backgroundColor value is applied.
* animate("5s", keyframes([
* style({ backgroundColor: "red", offset: 0 }),
* style({ backgroundColor: "blue", offset: 0.2 }),
* style({ backgroundColor: "orange", offset: 0.3 }),
* style({ backgroundColor: "black", offset: 1 })
* ]))
* ```
*
* Alternatively, if there are no `offset` values used within the style entries then the offsets
* will be calculated automatically.
*
* ```typescript
* animate("5s", keyframes([
* style({ backgroundColor: "red" }) // offset = 0
* style({ backgroundColor: "blue" }) // offset = 0.33
* style({ backgroundColor: "orange" }) // offset = 0.66
* style({ backgroundColor: "black" }) // offset = 1
* ]))
* ```
*
* {@example core/animation/ts/dsl/animation_example.ts region='Component'}

/**

* animation DSL language. If this information is new, please navigate to the {@link
* Component#animations component animations metadata page} to gain a better understanding of
* how animations in Angular are used.
*
* `transition` declares the {@link sequence sequence of animation steps} that will be run when the
* provided `stateChangeExpr` value is satisfied. The `stateChangeExpr` consists of a `state1 =>
* state2` which consists of two known states (use an asterix (`*`) to refer to a dynamic starting
* and/or ending state).
*
* A function can also be provided as the `stateChangeExpr` argument for a transition and this
* function will be executed each time a state change occurs. If the value returned within the
* function is true then the associated animation will be run.
*
* Animation transitions are placed within an {@link trigger animation trigger}. For an transition
* to animate to a state value and persist its styles then one or more {@link state animation
* states} is expected to be defined.
*
* ### Usage
*
* An animation transition is kicked off the `stateChangeExpr` predicate evaluates to true based on
* what the previous state is and what the current state has become. In other words, if a transition
* is defined that matches the old/current state criteria then the associated animation will be
* triggered.
*
* ```typescript
* // all transition/state changes are defined within an animation trigger
* trigger("myAnimationTrigger", [
* // if a state is defined then its styles will be persisted when the
* // animation has fully completed itself
* state("on", style({ background: "green" })),
* state("off", style({ background: "grey" })),
*
* // a transition animation that will be kicked off when the state value
* // bound to "myAnimationTrigger" changes from "on" to "off"
* transition("on => off", animate(500)),
*
* // it is also possible to do run the same animation for both directions
* transition("on <=> off", animate(500)),
*
* // or to define multiple states pairs separated by commas
* transition("on => off, off => void", animate(500)),
*
* // this is a catch-all state change for when an element is inserted into
* // the page and the destination state is unknown
* transition("void => *", [
* style({ opacity: 0 }),
* animate(500)
* ]),
*
* // this will capture a state change between any states
* transition("* => *", animate("1s 0s")),
*
* // you can also go full out and include a function
* transition((fromState, toState) => {
* // when `true` then it will allow the animation below to be invoked
* return fromState == "off" && toState == "on";
* }, animate("1s 0s"))
* ])
* ```
*
* The template associated with this component will make use of the `myAnimationTrigger` animation
* trigger by binding to an element within its template code.
*
* ```html
*
*
...
* ```
*
* #### The final `animate` call
*
* If the final step within the transition steps is a call to `animate()` that **only** uses a
* timing value with **no style data** then it will be automatically used as the final animation arc
* for the element to animate itself to the final state. This involves an automatic mix of
* adding/removing CSS styles so that the element will be in the exact state it should be for the
* applied state to be presented correctly.
*
* ```
* // start off by hiding the element, but make sure that it animates properly to whatever state
* // is currently active for "myAnimationTrigger"
* transition("void => *", [
* style({ opacity: 0 }),
* animate(500)
* ])
* ```
*
* ### Using :enter and :leave
*
* Given that enter (insertion) and leave (removal) animations are so common, the `transition`
* function accepts both `:enter` and `:leave` values which are aliases for the `void => *` and `*
* => void` state changes.
*
* ```
* transition(":enter", [
* style({ opacity: 0 }),
* animate(500, style({ opacity: 1 }))
* ]),
* transition(":leave", [
* animate(500, style({ opacity: 0 }))
* ])
* ```
*
* ### Boolean values
* if a trigger binding value is a boolean value then it can be matched using a transition
* expression that compares `true` and `false` or `1` and `0`.
*
* ```
* // in the template
*
...
*
* // in the component metadata
* trigger('openClose', [
* state('true', style({ height: '*' })),
* state('false', style({ height: '0px' })),
* transition('false <=> true', animate(500))
* ])
* ```
*
* ### Using :increment and :decrement
* In addition to the :enter and :leave transition aliases, the :increment and :decrement aliases
* can be used to kick off a transition when a numeric value has increased or decreased in value.
*
* ```
* import {group, animate, query, transition, style, trigger} from '@angular/animations';
* import {Component} from '@angular/core';
*
* @Component({
* selector: 'banner-carousel-component',

/**
* `animateChild` is an animation-specific function that is designed to be used inside of Angular's
* animation DSL language. It works by allowing a queried element to execute its own
* animation within the animation sequence.
*
* Each time an animation is triggered in angular, the parent animation
* will always get priority and any child animations will be blocked. In order
* for a child animation to run, the parent animation must query each of the elements
* containing child animations and then allow the animations to run using `animateChild`.
*
* The example HTML code below shows both parent and child elements that have animation
* triggers that will execute at the same time.
*
* ```html
*
*
*
*
*
* Hello
*
* one
*
*
* two
*
*
* three
*
*
* ```
*
* Now when the `exp` value changes to true, only the `parentAnimation` animation will animate
* because it has priority. However, using `query` and `animateChild` each of the inner animations
* can also fire:
*
* ```ts
* // parent-child.component.ts
* import {trigger, transition, animate, style, query, animateChild} from '@angular/animations';
* @Component({
* selector: 'parent-child-component',
* animations: [
* trigger('parentAnimation', [
* transition('false => true', [
* query('header', [
* style({ opacity: 0 }),
* animate(500, style({ opacity: 1 }))
* ]),
* query('@childAnimation', [
* animateChild()
* ])
* ])
* ]),
* trigger('childAnimation', [
* transition('false => true', [
* style({ opacity: 0 }),
* animate(500, style({ opacity: 1 }))
* ])
* ])
* ]
* })
* class ParentChildCmp {
* exp: boolean = false;
* }
* ```
*
* In the animation code above, when the `parentAnimation` transition kicks off it first queries to
* find the header element and fades it in. It then finds each of the sub elements that contain the
* `@childAnimation` trigger and then allows for their animations to fire.
*
* This example can be further extended by using stagger:
*
* ```ts
* query('@childAnimation', stagger(100, [
* animateChild()
* ]))
* ```
*
* Now each of the sub animations start off with respect to the `100ms` staggering step.
*
* ## The first frame of child animations
* When sub animations are executed using `animateChild` the animation engine will always apply the
* first frame of every sub animation immediately at the start of the animation sequence. This way
* the parent animation does not need to set any initial styling data on the sub elements before the
* sub animations kick off.
*
* In the example above the first frame of the `childAnimation`'s `false => true` transition
* consists of a style of `opacity: 0`. This is applied immediately when the `parentAnimation`
* animation transition sequence starts. Only then when the `@childAnimation` is queried and called
* with `animateChild` will it then animate to its destination of `opacity: 1`.
*
* Note that this feature designed to be used alongside {@link query query()} and it will only work
* with animations that are assigned using the Angular animation DSL (this means that CSS keyframes
* and transitions are not handled by this API).
*
* @experimental Animation support is experimental.

/**
* `query` is an animation-specific function that is designed to be used inside of Angular's
* animation DSL language.
*
* query() is used to find one or more inner elements within the current element that is
* being animated within the sequence. The provided animation steps are applied
* to the queried element (by default, an array is provided, then this will be
* treated as an animation sequence).
*
* ### Usage
*
* query() is designed to collect multiple elements and works internally by using
* `element.querySelectorAll`. An additional options object can be provided which
* can be used to limit the total amount of items to be collected.
*
* ```js
* query('div', [
* animate(...),
* animate(...)
* ], { limit: 1 })
* ```
*
* query(), by default, will throw an error when zero items are found. If a query
* has the `optional` flag set to true then this error will be ignored.
*
* ```js
* query('.some-element-that-may-not-be-there', [
* animate(...),
* animate(...)
* ], { optional: true })
* ```
*
* ### Special Selector Values
*
* The selector value within a query can collect elements that contain angular-specific
* characteristics
* using special pseudo-selectors tokens.
*
* These include:
*
* - Querying for newly inserted/removed elements using `query(":enter")`/`query(":leave")`
* - Querying all currently animating elements using `query(":animating")`
* - Querying elements that contain an animation trigger using `query("@triggerName")`
* - Querying all elements that contain an animation triggers using `query("@*")`
* - Including the current element into the animation sequence using `query(":self")`
*
*
* Each of these pseudo-selector tokens can be merged together into a combined query selector
* string:
*
* ```
* query(':self, .record:enter, .record:leave, @subTrigger', [...])
* ```
*
* ### Demo
*
* ```
* @Component({
* selector: 'inner',
* template: `
*
*
Title
*
* Blah blah blah
*
*
* `,
* animations: [
* trigger('queryAnimation', [
* transition('* => goAnimate', [
* // hide the inner elements
* query('h1', style({ opacity: 0 })),
* query('.content', style({ opacity: 0 })),
*
* // animate the inner elements in, one by one
* query('h1', animate(1000, style({ opacity: 1 })),
* query('.content', animate(1000, style({ opacity: 1 })),
* ])
* ])
* ]
* })
* class Cmp {
* exp = '';
*
* goAnimate() {
* this.exp = 'goAnimate';
* }
* }
* ```
*
* @experimental Animation support is experimental.

/**
* `stagger` is an animation-specific function that is designed to be used inside of Angular's
* animation DSL language. It is designed to be used inside of an animation {@link query query()}
* and works by issuing a timing gap between after each queried item is animated.
*
* ### Usage
*
* In the example below there is a container element that wraps a list of items stamped out
* by an ngFor. The container element contains an animation trigger that will later be set
* to query for each of the inner items.
*
* ```html
*
*
*
*
*
* {{ item }}
*
*
* ```
*
* The component code for this looks as such:
*
* ```ts
* import {trigger, transition, style, animate, query, stagger} from '@angular/animations';
* @Component({
* templateUrl: 'list.component.html',
* animations: [
* trigger('listAnimation', [
* //...
* ])
* ]
* })
* class ListComponent {
* items = [];
*
* showItems() {
* this.items = [0,1,2,3,4];
* }
*
* hideItems() {
* this.items = [];
* }
*
* toggle() {
* this.items.length ? this.hideItems() : this.showItems();
* }
* }
* ```
*
* And now for the animation trigger code:
*
* ```ts
* trigger('listAnimation', [
* transition('* => *', [ // each time the binding value changes
* query(':leave', [
* stagger(100, [
* animate('0.5s', style({ opacity: 0 }))
* ])
* ]),
* query(':enter', [
* style({ opacity: 0 }),
* stagger(100, [
* animate('0.5s', style({ opacity: 1 }))
* ])
* ])
* ])
* ])
* ```
*
* Now each time the items are added/removed then either the opacity
* fade-in animation will run or each removed item will be faded out.
* When either of these animations occur then a stagger effect will be
* applied after each item's animation is started.
*
* @experimental Animation support is experimental.

/*
* [Validation]
* The visitor code below will traverse the animation AST generated by the animation verb functions
* (the output is a tree of objects) and attempt to perform a series of validations on the data. The
* following corner-cases will be validated:
*
* 1. Overlap of animations
* Given that a CSS property cannot be animated in more than one place at the same time, it's
* important that this behaviour is detected and validated. The way in which this occurs is that
* each time a style property is examined, a string-map containing the property will be updated with
* the start and end times for when the property is used within an animation step.
*
* If there are two or more parallel animations that are currently running (these are invoked by the
* group()) on the same element then the validator will throw an error. Since the start/end timing
* values are collected for each property then if the current animation step is animating the same
* property and its timing values fall anywhere into the window of time that the property is
* currently being animated within then this is what causes an error.
*
* 2. Timing values
* The validator will validate to see if a timing value of `duration delay easing` or
* `durationNumber` is valid or not.
*
* (note that upon validation the code below will replace the timing data with an object containing
* {duration,delay,easing}.
*
* 3. Offset Validation
* Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
* Offsets within keyframes() are considered valid when:
*
* - No offsets are used at all
* - Each style() entry contains an offset value
* - Each offset is between 0 and 1
* - Each offset is greater to or equal than the previous one
*
* Otherwise an error will be thrown.

/*
* The code within this file aims to generate web-animations-compatible keyframes from Angular's
* animation DSL code.
*
* The code below will be converted from:
*
* ```
* sequence([
* style({ opacity: 0 }),
* animate(1000, style({ opacity: 0 }))
* ])
* ```
*
* To:
* ```
* keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
* duration = 1000
* delay = 0
* easing = ''
* ```
*
* For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
* combination of prototypical inheritance, AST traversal and merge-sort-like algorithms are used.
*
* [AST Traversal]
* Each of the animation verbs, when executed, will return an string-map object representing what
* type of action it is (style, animate, group, etc...) and the data associated with it. This means
* that when functional composition mix of these functions is evaluated (like in the example above)
* then it will end up producing a tree of objects representing the animation itself.
*
* When this animation object tree is processed by the visitor code below it will visit each of the
* verb statements within the visitor. And during each visit it will build the context of the
* animation keyframes by interacting with the `TimelineBuilder`.
*
* [TimelineBuilder]
* This class is responsible for tracking the styles and building a series of keyframe objects for a
* timeline between a start and end time. The builder starts off with an initial timeline and each
* time the AST comes across a `group()`, `keyframes()` or a combination of the two wihtin a
* `sequence()` then it will generate a sub timeline for each step as well as a new one after
* they are complete.
*
* As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
* timeline was created (based on one of the cases above) then the parent timeline will attempt to
* merge the styles used within the sub timelines into itself (only with group() this will happen).
* This happens with a merge operation (much like how the merge works in mergesort) and it will only
* copy the most recently used styles from the sub timelines into the parent timeline. This ensures
* that if the styles are used later on in another phase of the animation then they will be the most
* up-to-date values.
*
* [How Missing Styles Are Updated]
* Each timeline has a `backFill` property which is responsible for filling in new styles into
* already processed keyframes if a new style shows up later within the animation sequence.
*
* ```
* sequence([
* style({ width: 0 }),
* animate(1000, style({ width: 100 })),
* animate(1000, style({ width: 200 })),
* animate(1000, style({ width: 300 }))
* animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
* else
* ])
* ```
*
* What is happening here is that the `height` value is added later in the sequence, but is missing
* from all previous animation steps. Therefore when a keyframe is created it would also be missing
* from all previous keyframes up until where it is first used. For the timeline keyframe generation
* to properly fill in the style it will place the previous value (the value from the parent
* timeline) or a default value of `*` into the backFill object. Given that each of the keyframe
* styles are objects that prototypically inhert from the backFill object, this means that if a
* value is added into the backFill then it will automatically propagate any missing values to all
* keyframes. Therefore the missing `height` value will be properly filled into the already
* processed keyframes.
*
* When a sub-timeline is created it will have its own backFill property. This is done so that
* styles present within the sub-timeline do not accidentally seep into the previous/future timeline
* keyframes
*
* (For prototypically-inherited contents to be detected a `for(i in obj)` loop must be used.)
*
* [Validation]
* The code in this file is not responsible for validation. That functionality happens with within
* the `AnimationValidatorVisitor` code.
