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!)

I think we hit a edge case here:
https://stackoverflow.com/questions/33891709/when-flexbox-items-wrap-in-column-mode-container-does-not-grow-its-width
as is differs here from chrome, but I think that yoga is here more correct.
So I haven't added this test yet as this would fail against chrome, as chrome outputs a width of 30 for root, whereas yoga gets a width of 60 here, which I think is correct. Strangely the output of ```flex-wrap:wrap``` is in jsfiddle also only with a (visual) width of 30 on chrome, while the tests gets generated with 60.
```html
<div id="wrap_reverse_column" style="height: 100px; flex-wrap: wrap-reverse">
<div style="height: 30px; width: 30px;"></div>
<div style="height: 30px; width: 30px;"></div>
<div style="height: 30px; width: 30px;"></div>
<div style="height: 30px; width: 30px;"></div>

Summary: This is an update of facebook/yoga#368 which was reverted. It fixes support for align-content: strech with multiple lines. The problem with the last attempt at solving this was that align-items:stretch was interfering. We handle this now by detecting when the flex basis of the children hints at them overflowing. This is not 100% correct as the size of the items could change when remeasuring but it will work in 99% of cases.
