987 * [Validation]
988 * The visitor code below will traverse the animation AST generated by the animation verb functions
989 * (the output is a tree of objects) and attempt to perform a series of validations on the data. The
990 * following corner-cases will be validated:
991 *
992 * 1. Overlap of animations
993 * Given that a CSS property cannot be animated in more than one place at the same time, it's
994 * important that this behavior is detected and validated. The way in which this occurs is that
995 * each time a style property is examined, a string-map containing the property will be updated with
996 * the start and end times for when the property is used within an animation step.
997 *
998 * If there are two or more parallel animations that are currently running (these are invoked by the
999 * group()) on the same element then the validator will throw an error. Since the start/end timing
1000 * values are collected for each property then if the current animation step is animating the same
1001 * property and its timing values fall anywhere into the window of time that the property is
1002 * currently being animated within then this is what causes an error.
1003 *
1004 * 2. Timing values
1005 * The validator will validate to see if a timing value of `duration delay easing` or
1006 * `durationNumber` is valid or not.
1007 *
1008 * (note that upon validation the code below will replace the timing data with an object containing
1009 * {duration,delay,easing}.
1010 *
1011 * 3. Offset Validation
1012 * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
1013 * Offsets within keyframes() are considered valid when:
1014 *
1015 * - No offsets are used at all
1016 * - Each style() entry contains an offset value
1017 * - Each offset is between 0 and 1
1018 * - Each offset is greater to or equal than the previous one
1019 *
1020 * Otherwise an error will be thrown.

1535 * The code within this file aims to generate web-animations-compatible keyframes from Angular's
1536 * animation DSL code.
1537 *
1538 * The code below will be converted from:
1539 *
1540 * ```
1541 * sequence([
1542 * style({ opacity: 0 }),
1543 * animate(1000, style({ opacity: 0 }))
1544 * ])
1545 * ```
1546 *
1547 * To:
1548 * ```
1549 * keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
1550 * duration = 1000
1551 * delay = 0
1552 * easing = ''
1553 * ```
1554 *
1555 * For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
1556 * combination of prototypical inheritance, AST traversal and merge-sort-like algorithms are used.
1557 *
1558 * [AST Traversal]
1559 * Each of the animation verbs, when executed, will return an string-map object representing what
1560 * type of action it is (style, animate, group, etc...) and the data associated with it. This means
1561 * that when functional composition mix of these functions is evaluated (like in the example above)
1562 * then it will end up producing a tree of objects representing the animation itself.
1563 *
1564 * When this animation object tree is processed by the visitor code below it will visit each of the
1565 * verb statements within the visitor. And during each visit it will build the context of the
1566 * animation keyframes by interacting with the `TimelineBuilder`.
1567 *
1568 * [TimelineBuilder]
1569 * This class is responsible for tracking the styles and building a series of keyframe objects for a
1570 * timeline between a start and end time. The builder starts off with an initial timeline and each
1571 * time the AST comes across a `group()`, `keyframes()` or a combination of the two wihtin a
1572 * `sequence()` then it will generate a sub timeline for each step as well as a new one after
1573 * they are complete.
1574 *
1575 * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
1576 * timeline was created (based on one of the cases above) then the parent timeline will attempt to
1577 * merge the styles used within the sub timelines into itself (only with group() this will happen).
1578 * This happens with a merge operation (much like how the merge works in mergesort) and it will only
1579 * copy the most recently used styles from the sub timelines into the parent timeline. This ensures
1580 * that if the styles are used later on in another phase of the animation then they will be the most
1581 * up-to-date values.
1582 *
1583 * [How Missing Styles Are Updated]
1584 * Each timeline has a `backFill` property which is responsible for filling in new styles into
1585 * already processed keyframes if a new style shows up later within the animation sequence.
1586 *
1587 * ```
1588 * sequence([
1589 * style({ width: 0 }),
1590 * animate(1000, style({ width: 100 })),
1591 * animate(1000, style({ width: 200 })),
1592 * animate(1000, style({ width: 300 }))
1593 * animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
1594 * else
1595 * ])
1596 * ```
1597 *
1598 * What is happening here is that the `height` value is added later in the sequence, but is missing
1599 * from all previous animation steps. Therefore when a keyframe is created it would also be missing
1600 * from all previous keyframes up until where it is first used. For the timeline keyframe generation
1601 * to properly fill in the style it will place the previous value (the value from the parent
1602 * timeline) or a default value of `*` into the backFill object. Given that each of the keyframe
1603 * styles are objects that prototypically inhert from the backFill object, this means that if a
1604 * value is added into the backFill then it will automatically propagate any missing values to all
1605 * keyframes. Therefore the missing `height` value will be properly filled into the already
1606 * processed keyframes.
1607 *
1608 * When a sub-timeline is created it will have its own backFill property. This is done so that
1609 * styles present within the sub-timeline do not accidentally seep into the previous/future timeline
