8b2e6c365d Add newer fixtures
Summary:
flexlayout has the same fixtures forked from Yoga, with some disabled, and some added. This syncs that list to Yoga, adding the fixes made to it along with new fixtures.

One new test absolute_child_with_max_height_larger_shrinkable_grandchild is failing, along with two fixtures where Chrome had recently changed its behaviors. These are commented out at the moment before I do something smarter with the test runner to allow more fixtures.

ba27f9d1ec fix: remove gap if its last element in line (fix flex gap extra spacing when children determine parents main axis size) (#1188)
Summary:
Fixes - https://github.com/facebook/react-native/issues/35553

## Approach
We're using `betweenMainDim` to add [gap between](bbeede82d3/yoga/Yoga.cpp (L2495)) items in main axis. This is resulting in increased [main axis](bbeede82d3/yoga/Yoga.cpp (L2598)) dimension of the container as it gets added even for the last element. One solution is to keep using it and subtract the gap when last element is reached.

## Aside
Mutating this value feels weird, but I think `betweenMainDim` gets initialized for every line so should be fine? I did some manual tests to verify. I tried running tests but I'll have to downgrade the java version. Let me know if anything fails. Thanks! 🙏

5a257aac85 Add tests for gap interaction with child margins
Summary:
Adds a couple test fixtures to validate the interaction of flex gap with children with margins. In both Yoga, and web browsers, these are additive vs collapsing.

8166c81135 Incorporate gap space into main axis overflow flag (#1173)
Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1173

In https://github.com/facebook/react-native/issues/35351 we see incorrect child item height when the flex-wrap is enabled, the cross-axis is to be stretched, and main-axis overflow is caused by gap.

In YGDistributeFreeSpaceSecondPass, if we do not have overflow (determined by flexBasisOverflows), we have stretch cross-alignment, and we reason that nothing can add to main axis dimensions, we know we're a single line and want to take full cross dimensions. and can set YGMeasureModeExactly which uses parent dimensions. Guessing an optimization?

If we do have overflow, then we set YGMeasureModeAtMost to find minimum possible cross-axis dimensions instead.

`flexBasisOverflows` incorporates both computed flex basis, and margin, so it is more generally a flag for whether we will wrap. So we should incorporate gap spacing into it. E.g. it is also used for whether we should the match main axis parent dimension of the overall container. This change does just that, and renames the flag to `mainAxisOverflows`.

We will want to cherry-pick the fix for this into RN 0.71 since we have not yet introduced the community to the incorrect behavior, and we expect a lot of usage of flex-gap.

c2a0ccf0d4 Add tests for row-gap and column-gap
Summary:
This adds the fixtures from https://github.com/facebook/yoga/pull/1116 and generates tests.

This adds a good amount of coverage, but I plan to follow up with a diff adding a bit more, e.g. for interactions with flex direction of column when we should no-op, etc. I also discovered the current fixtures do not allow testing shorthand props like "gap" without changes.

This also updates the `webdrivers` gem to respond to a break with chromedriver on m1 macs from 4 days ago https://github.com/titusfortner/webdrivers/pull/239.

fd180de774 Fix Generation of Tests from Fixtures
Summary:
https://github.com/facebook/yoga/pull/1116 added a change to the test generator "gentests.rb" to support a newer version of chromedriver, along with a change to the enum generator (not touched in this diff) to produce code consistent with the current tests, which seem to have been manually edited since last generation.

I had trouble running the test generator locally, because it relies on unversioned third-party dependencies, whose APIs change. Looking at source history, it seems like each time someone wants to run the script, they end up updating its syntax to match whatever versions they pull in.

This change adds a Gemfile and lock so that that the version of "watir" is locked, and so that we will also automatically pull in a consistent "chomedriver" version via the "webdrivers" gem. It includes the updates from the PR to be consistent with already output tests, and I have also updated the copyright header generation to no longer create lint warnings on newly generated tests (some of the previous ones were fixed manually it looks like).

The test generator would still produce bodies which would fail clang-format, and were manually edited (causing generation to emit new lint warnings), so I updated the generator to suppress clang-format in the body of the generated files.

Three tests, around the interaction of minimum dimensions and flexible children produce different results in Chrome now compared to when the tests were added, so running `gentests.rb` creates tests which break UTs. This doesn't seem like any sort of rounding, or device specific difference, so I have disabled these tests for now. While digging around, it does look like Chrome periodically will fix bugs in its own layout implementation which cause differences, like https://bugs.chromium.org/p/chromium/issues/detail?id=927066

bc7e504b29 Fix bugs around align-content
Summary:
@public

Regenerating the “golden master” tests with chrome surfaced different bugs around `align-content`:

- a misunderstanding that values in `align-content` only applied *if there is only one line.* In fact, it applies *every time* a container is set to `flex-wrap: wrap`. Chrome had this wrong, and as such our tests were generated with incorrect parameters.
- empty children growing to the cross axis size of the container, even when `align-content` is different from `stretch`. This was implemented incorrectly in Chrome as well. Here, we fix it with an extra check.

1fc8472d35 gentest: allow for different default values
Summary:
@public

We use Chrome for generating test cases, which since v67 (or so) for `min-width` and `min-height` has a default value of either `0px` (CSS 2) or `auto` (CSS 3), depending on style properties.

Our setup only allowed for a single default value, and our test cases produce *both.*
This changes the test gen logic to allow for more than one value.

The only thing I found in the spec for this change is the following. Not exactly sure if this is the thing this PR is about:

> For each flex item, subtract its outer flex base size from its max-content contribution size. If that result is not zero, divide it by (if the result was positive) its **flex grow factor floored at 1** or (if the result was negative) by its scaled flex shrink factor, having **floored the flex shrink factor at 1**. This is the item’s max-content flex fraction.

But at least it seems a required change.

3db38f2a80 Remove rounding from experimental features
Summary: Rounding has been successfully adopted by multiple products and frameworks. Time to move it out of experimental mode. Rounding can still be turned of by setting the point scale factor to 0 on the config.

aa5b296ac7 New round-to-pixel-grid algorithm that fixes possible subpixel gaps between sibling nodes
Summary:
This diff introduces new, little bit sophisticated round-to-pixel-grid algorithm.

**Motivation:**

Previous simple and straightforward solution works in most cases but sometimes produce the not-so-great result. A while ago Nick Lockwood described this problem and proposed the solution in RN's RCTShadowView class:

For example, say you have the following structure:

  // +--------+---------+--------+
  // |        |+-------+|        |
  // |        ||       ||        |
  // |        |+-------+|        |
  // +--------+---------+--------+

Say the screen width is 320 pts so the three big views will get the following x bounds from our layout system:
{0, 106.667}, {106.667, 213.333}, {213.333, 320}
Assuming screen scale is 2, these numbers must be rounded to the nearest 0.5 to fit the pixel grid:
{0, 106.5}, {106.5, 213.5}, {213.5, 320}
You'll notice that the three widths are 106.5, 107, 106.5.

This is great for the parent views but it gets trickier when we consider rounding for the subview. When we go to round the bounds for the subview in the middle, it's relative bounds are {0, 106.667} which gets rounded to {0, 106.5}. This will cause the subview to be one pixel smaller than it should be. This is why we need to pass in the absolute position in order to do the rounding relative to the screen's grid rather than the view's grid. After passing in the absolutePosition of {106.667, y}, we do the following calculations:
absoluteLeft = round(absolutePosition.x + viewPosition.left) = round(106.667 + 0) = 106.5
absoluteRight = round(absolutePosition.x + viewPosition.left + viewSize.width) + round(106.667 + 0 + 106.667) = 213.5
width = 213.5 - 106.5 = 107

You'll notice that this is the same width we calculated for the parent view because we've taken its position into account.

I believe this is awesome. I also believe that we have to decouple this logic from RN and put it into awesome Yoga. So I did it in this diff.

**Fun fact:**
The original implementation of this algorithm in RN had (and still have) a bug, which was found by Dustin dshahidehpour and fixed in D4133643. Therefore that diff was unlanded because it broke something unrelated inside RN text engine. I will fix that problem in RN later.

**Why do we need to change test methodology?**
Because the way we receive layout metrics from Chrome browser actually directly related to rounding problem. Previously we used `offsetHeight` and `offsetWidth` properties of the DOM node, which contain naively rounded values from `computedStyle` or `getBoundingClientRect`. (Which is we are trying to fix!) So, I added the new function that computes node size using two-step-rounding approach, conceptually similar to one that implemented in Yoga. Note: Chrome browser performs rounding layout as part of rendering process and actual values that can ve computed by counting actual pixel are different from these natively rounded ones.

**Why do some tests now have different desired values?**
These changes actually prove that my approach is correct and more useful for actual view rendering goals. So, let's take a look at test with changed values `rounding_fractial_input_3`:
Previously: 64+25+24=114 (Incorrect!)
Now: 65+24+25=114 (Correct!)
Previously: 64+25+24=114 (Incorrect!)
Now: 65+24+25=114 (Correct!)
