The size of the containing block is the size of the padding box of the containing node for absolute nodes. We were looking at `containingNode->getLayout().measuredDimension(Dimension::Width)` which is the border box. So we need to subtract the border from this.

Absolute nodes can be laid out by themselves and do not have to care about what is happening to their siblings. Because of this we can make `positionAbsoluteChild` the sole place where we handle this logic. Right now that is scattered around algorithm with many `if (child is absolute)` cases everywhere. This makes implementing position static a lot harder since we are relying on the CB to do all this work, not the parent.
With this change the only time we set position for an absolute node and it matter (i.e. not overwritten) is in `positionAbsoluteChild`

Gentest code has a problem where we try to apply a border in our test when the web browser is not actually adding one. This happens when we do something like `border-top: 10px`. This will actually set the style of the border to `initial` which is just `none`, so nothing renders. This is causing at least 1 test to pass when it actually fails.
I changed it so we ignore setting this value if the style is one of these values. I then re-ran the gentest code and excluded the now failing test (which gets fixed in my static stack).

This is a copy of D51369722 to make it so that it preserves the file history
CalculateLayout.cpp is massive and approaching 3k lines. I added a few large functions dealing with layout of absolute nodes and was thinking it would be nice if that logic was just in its own file so it was more isolated and easier to reason about. So I made AbsoluteLayout.cpp and AbsoluteLayout.h to house this logic. In order for this to work I had to expose calculateLayoutInternal in CalculateLayout.h as layoutAbsoluteChild calls it. This is unideal and I would like to find a better way...
I also make LayoutUtils.h to house misc small helper methods as they are called in AbsoluteLayout.cpp and CalculateLayout.cpp

Pull Request resolved: https://github.com/facebook/yoga/pull/1479
X-link: https://github.com/facebook/react-native/pull/41682
There are two ways to get the value of a style for a specific edge right now:
1) From the inline start/end edge which is determined via the writing direction (ltr or rtl), assuming you do not have errata on
2) From the flex start/end edge which is determined via the flex direction (row, row-reverse, column, column-reverse)
There is a weird curiosity in the second case: you can define a style to be on the "start" or "end" edge when writing the stylex/css. The physical edge that this refers to is dependent on the writing direction. So `start` would be `left` in `ltr` and `right` in `rtl`, with `end` the opposite. It is **never** determined via the flex direction. Additionally, `start`/`end` takes precedence over the physical edge it corresponds to in the case both are defined.
So, all of this means that to actually get the value of a style from the flex start/end edges, we need to account for the case that one of these relative edges was defined and would overwrite any physical edge. Since this mapping is solely determined by the writing direction, we need to pass that in to all the flex start/end getters and do that logic. This is done in `flexStartRelativeEdge`/`flexEndRelativeEdge` which was added earlier but for some reason only being used on border.

Pull Request resolved: https://github.com/facebook/yoga/pull/1473
X-link: https://github.com/facebook/react-native/pull/41491
To simplify the logic a bit I introduce a new function called `positionAbsoluteChild`. This function will, eventually, be the **sole function that matters** when determining the layout position of an absolute node. Because [absolute nodes do not participate in flex layout](https://drafts.csswg.org/css-flexbox/#abspos-items), we can determine the position of said node independently of its siblings. The only information we need are the node itself, its parent, and its containing block - which we have all of in `layoutAbsoluteChild`.
Right now, however, this is purely a BE change with no functionality different. There was a big set of if statements at the end of `layoutAbsoluteChild` that would position the node on the main and cross axis for certain cases. The old code had it so that the main and cross axis had basically the same logic but the code was repeated. This puts that logic, as is, in `positionAbsoluteChild` and calls that from `layoutAbsoluteChild`.
I will soon edit this function to actually do what it is envisioned to do (i.e. be the sole place that position is set for absolute nodes).

Pull Request resolved: https://github.com/facebook/yoga/pull/1472
This change has most of the logic needed for supporting `position: static`. We do two things here that fix a lot of the broken static test:
1) We pass in the containing node to `layoutAbsoluteChild` and use it to properly position the child in the case that insets are defined.
2) We rewrite the absolute child's position to be relative to it's parent in the event that insets are defined for that child (and thus it is positioned relative to its CB). Yoga's layout position has always be relative to parent, so I feel it is easier to just adjust the coordinates of a node to adhere to that design rather than change the consumers of yoga.
The "hard" part of this algorithm is determining how to iterate the offset from the containing block needed to do this translation described above. That is handled in `layoutAbsoluteDescendants`.

If we are going to allow the containing block to layout its absolute descendants and NOT the direct parent then we need to change step 11 which is concerned with setting the trailing position in the case we are row or column reverse. This is the very last step in the function and is positioned that way because it operates on the assumption that all children have their position set by this time. That is no longer a valid assumption if CBs layout their absolute children. In that case the CB also needs to take care of setting the position here.
Because of this problem I moved some things around. It now works like:
* If errata is set, the direct parent will set trailing position for all non absolute children in step 11
* If errata is set the CB will set trailing position of absolute descendants after they are laid out inside of layoutAbsoluteDescendants

Summary:

Pull Request resolved: https://github.com/facebook/yoga/pull/1470
The way we plan on implementing `position: static` is by changing how we lay out absolutely positioned nodes. Instead of letting their direct parent lay them out we are going to let their containing block handle it. This is useful because by the time the containing block gets to this step it will already know its size, which is needed to ensure that absolute nodes can get the right value with percentage units. Additionally, it means that we can "translate" the position of the absolute nodes to be relative to their parent fairly easily, instead of some second pass that would not be possible with a different design.
This change just gets the core pieces of this process going. It makes it so that containing blocks will layout out absolute descendants that they contain. We also pass in the containing block size to the owner size args for `layoutAbsoluteChild`. This new path will only happen if we have the errata turned off. If there is no positioned ancestor for a given node we just assume the root is. This is not exactly how it works on the web - there is a notion of an initial containing block - but we are not implementing that as of right now.

Yoga passes `MeasureMode`/`YGMeasureMode` to express constraints in how a box should be measured, given definite or indefinite available space.
This is modeled after Android [MeasureSpec](https://developer.android.com/reference/android/view/View.MeasureSpec), with a table above `calculateLayoutImpl()` explaining the CSS terms they map to. This can be confusing when flipping between the spec, and code.
This switches internal usages to the CSS terms, but leaves around `YGMeasureMode` since it is the public API passed to measure functions.

This change renames usages of `CompactValue` to `Style::Length`, which will be Yoga's representation for CSS input lengths. Right now one is just a type alias of the other, but this will let us change the internals of CompactValue with the rest of the world looking the same.
A few factory functions are added to `yoga::value` for creating CSS values. There are some shenanigans around how we want to represent CSS pixels (one YGUnitPoint), when we also end up adding CSS points (slightly larger than one YGUnitPoint). For now, I reused `point` until making other changes.

This follows the previous patterns used for `Gutters` and `Dimension`, where we hide CompactValue array implementation from `yoga::Style` callers.
This allows a single read of a style to only need access to the resolved values of a single edge, vs all edges. This is cheap now because the interface is the representation, but gets expensive if `StyleValuePool` is the actual implementation.
This prevents us from needing to resolve nine dimensions, in order to read a single value like `marginLeft`. Doing this, in the new style, also lets us remove `IdxRef` from the API.
We unroll the structure dependent parts in the props parsing code, for something more verbose, but also a bit clearer.

NickGerleman pointed out that my recent changes to fix the slew of row-reverse problems in Yoga actually ended up regressing some parts. Specifically, absolute children of row-reverse containers would have their insets set to the wrong side. So if you set left: 10 it would apply it to the right.
Turns out, in `layoutAbsoluteChild` there were cases where we were applying inlineStart/End values to the flexStart/End edge, which can never be right. So I changed the values to also be flexStart/End as the fix here.

Summary:
`child.offsetLeft/Top` calculates the offset from child to its nearest positioned ancestor, not its direct parent. These are often the same and have not mattered in the past since we have not supported position static. Since are are in the process of supporting that, we would like our tests to be usable so this adjusts the gentest methodology to only speak the same language as Yoga - that is left/top are always relative to direct parents.
It works by using `getBoundingClientRect().left/top` instead. Then we pass that down to children and subtract it from the childs `getBoundingClientRect()` to get the position relative to the parent. Note we have to round the final result as `child.offsetLeft/Top` is rounded.

This dramatically simplifies the matrix of Node vs web, ASM vs WASM, sync vs async compilation, or CommonJS vs ES Modules. We have one variant, using wasm, with ESModule top-level await to do async compilation. Web/node share the same binary, and we base64 encode the WASM into a wrapper JS file for compatibility with Node and bundlers.
This has some downsides, like requiring an environment with top level await, but also has upsides, like a consistent, sync looking API compatible with older Yoga, and mitigating TypeScript issues with package exports and typings resolution.
As part of this work I also removed `ts-node` from the toolchain (at the cost of a couple of config files needing to be vanilla JS).

I will use this errata to gate my changes that actually make position: static behave like the web. We have future plans to make position: relative the default again but users could still have declared certain nodes as position: static, so I think this is needed regardless.

Summary:
Doing some test-driven-development to support this feature, so I will start by adding a ton of tests to ensure the nuance of position: static is captured in Yoga. Specifically I have a slew of tests to capture:
* Insets have no effect on static elements
* Insets are relative to the nearest non-static ancestor
* Percentage values for insets, padding, and margin of absolute children respect the correct dimension of the nearest non-static ancestor
* Also added similar ones for static and relative children which should just respect their ancestor (static only because it is a flexbox by default)
* This rule does NOT apply to border
* The containing block for absolute children is the padding box of their nearest non-static ancestor
* The containing block for static children is the content box of their parent (because all elements are flex containers in yoga, at least right now)

Summary:
I am about to embark on supporting `position: static` in Yoga. The enum exists already (and is the default position type, lol) but does not actually do anything and just behaves like `position: relative`.
My approach here is to write a bunch of tests to test for the various behaviors of static positions and then develop on Yoga afterwards to get those tests passing. To do this, we need to make a few changes to the gentest files as there is not support for adding `position: static` at the moment:
* Make it so that the gentest code can physically write `YGPositionTypeStatic` if it encounters `position: static` in the style
* Make it so that gentest.js knows that Yoga's default is actually static. This way the code generated in the tests will actually label nodes for non default values
* Explicitly label the position type even when it is not declared in the style prop (with the exception of the default)
* Regenerate all the tests
Additionally I added the first, basic test: making sure insets do nothing on a statically positioned element.

Summary: Now that the tests are passing let's not skip it anymore. Also adding errata tests to make sure most prod builds are still protected.
