/*
* 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 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 within 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 map. The `copyStyles` method in util.ts
* handles propagating that backfill map to the styles object.
*
* 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
*
* [Validation]
* The code in this file is not responsible for validation. That functionality happens with within
* the `AnimationValidatorVisitor` code.

/*
When the keyframe is stretched then it means that the delay before the animation
starts is gone. Instead the first keyframe is placed at the start of the animation
and it is then copied to where it starts when the original delay is over. This basically
means nothing animates during that delay, but the styles are still rendered. For this
to work the original offset values that exist in the original keyframes must be "warped"
so that they can take the new keyframe + delay into account.
delay=1000, duration=1000, keyframes = 0 .5 1
turns into
delay=0, duration=2000, keyframes = 0 .33 .66 1
