ada4831580 Eliminate YGFloatOptional::getValue()
Summary:
@public

Replace `YGFloatOptional::getValue()` with `YGFloatOptional::unwrap()`.

`YGFloatOptional::getValue()` has the unfortunate property of calling `std::exit` if the wrapped value is undefined.

Here, we eliminate the method, and just call `.unwrap()` everywhere.

ee6b0d6658 Fix aspect ratio when stretching with main axis margin (#834)
Summary:
I've noticed that when a child's size is determined by `align-items: stretch` in combination with `aspect-ratio` its size is wrongly calculated to account for margin in the main axis when there is more than enough space.

See playground: https://goo.gl/tgW6cD

I've yet to figure out exactly how to solve this but i've started by writing a failing test when can be seen in the first commit here.

I assumed I had found the bug here https://github.com/facebook/yoga/blob/master/yoga/Yoga.cpp#L1838 where margin is being subtracted from the desired width even though the measure mode tells it to measure to exactly that size. However, if we don't remove this margin from the available width then 15 tests fail (including the one I just added) not quite figured out why yet. I'm also a bit confused at to why this would only happen for nodes with `aspect-ratio` and not for nodes where an explicit height and width is set.

`YGFloatOptional::getValue()` has the unfortunate property of calling `std::exit` if the wrapped value is undefined.
That forces `x.isUndefined() ? fallback : x.getValue()` as access pattern.

Currently only parent can tell the layout to align its children based on baseline. But if one of the children is a column or row then basealign does not work as expected.

We have added an api setReferenceBaseline which when set to true would mean that it's baseline would be considered as the reference baseline for parent amongst its siblings. If there are more than one siblings with referenceBaseline set, the first one would be considered.

d9792b3e59 Exclude cpp equality operators from extern "C"
Summary:
`extern "C"` disables name mangling, hence input parameter types does not influence the name. That makes it impossible to have several equality operators with `extern "C"` linkage (for different types).

One such operator is defined in Windows SDK, in `guiddef.h`. It in turn is included in `winnt.h` inside `extern "C" { ... }` block. Trying to compile file which both is dependent both on `winnt.h` and `Yoga.h` results in:
```
Yoga.h(50): error C2733: 'operator ==': second C linkage of overloaded function not allowed
guiddef.h(192): note: see declaration of 'operator =='
```

In general it doesn't make much sense to have cpp specific operator to have `extern "C"` linkage, so the change doesn't introduce any controlling flag (mangling on/off).

Note that it's breaking binary compatibility and yoga library should be rebuilt if those operators are used.

f90c9b5292 When paddingStart is 0, it should override paddingHorizontal (#816)
Summary:
Fixes #815

Imagine a node with this style: `{ paddingHorizontal: 10, paddingStart: 0 }`.

After running layout on this node, we expect its computed `paddingStart` to be `0`. However, it is actually `10`.

Consider the expression `paddingEdgeStart.getValue() > 0.0f` in [`getLeadingPadding`](328ec7dc4d/yoga/YGNode.cpp (L461)). Why is `0` handled like a negative number rather than a positive number? I suspect this should be `>=` so `0` is handled like the positive numbers (this is how `getTrailingPadding` works).

It looks like 3a82d2b1a8 (diff-07b4949bf42749fde386e769ff08a124) changed the operator from `>=` to `>` in `getLeadingPadding`. I suspect it was a mistake. `getTrailingPadding` still uses `>=`.

I manually verified this using the code in #815 and added some unit tests to catch this bug and other similar issues.

af8c69ecf7 Fix rounding of negative numbers (#825)
Summary:
`YGRoundValueToPixelGrid` currently rounds negative numbers incorrectly. For example:

```
YGRoundValueToPixelGrid(-2.2, 1.0, /* ceil */ false, /* floor */ true) = -2.0
```

However, that operation is supposed to take the floor of the number so the result should acutally be `-3.0`.

There's a detailed comment in `YGRoundValueToPixelGrid` about the fix and why it works.

A symptom that manifested because of this bug is that text nodes could get smaller and smaller on each layout pass. For details see https://github.com/facebook/yoga/issues/824.

Fixes #824

780ced4d07 Fix C# unit tests (#818)
Summary:
This consists of several fixes:
  - Some of the C++ functions called by the tests were missing `WIN_EXPORT`
  - It looks like Yoga was changed to round up after `TestMeasureFuncWithFloat` was written. Here's the function call that results in the rounding: 357ca78f9f/yoga/Yoga.cpp (L4019-L4026)
  - The format of the result of the `Print` method was changed after `TestPrint` was written.

Summary:
This diff fixes the height calculation logic for the nodes with baseline. Before height calculation for baseline was done at wrong place.

The task was created due to the regression caused by D9219678.

5be1726d28 Solve width bug when the size is less than min
Summary:
This diff updates the logic which reassigns `remainingFreeSpace` when the node's calculated dimension falls below min width of the node.

So we will have to update the `remainingFreeSpace` as there is more available space since the calculated nodes width is less than the min width.

I have also added comments at relevant places in the code so that it is clearer.

This diff solves the issue raised in litho support grp. The details can be found here T32199608. This diff also makes sure that it doesn't break fblite, as the earlier version broke it, details of which can be found here T32881750.
