Sebastian Markbage a80dd9a92a Fix up this pattern var React = require('react-native');
Summary:First I searched for special cases that destructor PropTypes:

```
(?s)React\s*=\s*require\('react\-native'\).*(Children|PropTypes)[^\{\}]*\}\s*=\s*React;
```

I split them up manually.

Then I replaced the React = require('react-native') + destructuring pattern...

```
(?s)(const|var)\s+React\s*=\s*require\('react\-native'\)(.*[^\{\}]*\}\s*=\s*)React;
```

...with...

```
$1 React = require('react');
$1 ReactNative = require('react-native')$2ReactNative;
```

I used lint to figure out if I left some unnecessary imports.

Finally I grepped for just

```
React\s*=\s*require\('react\-native'\)
```

to catch any remaining patterns.

Also, `} = React.NativeModules` -> `} = ReactNative.NativeModules`.

Adam Roth 9c73e2ff7a [Image] Improved loading of Assets Library and Photos Framework images.
Summary:
Update to https://github.com/facebook/react-native/pull/1969

--
Recent improvements allow RCTImageLoader to select a more appropriate sized image based on the layout dimensions. Sizes:

	- asset.thumbnail
	- asset.aspectRatioThumbnail
	- asset.defaultRepresentation.fullScreenImage
	- asset.defaultRepresentation.fullResolutionImage

Prior, only the fullResolutionImage was used. This was memory intensive and resulted in crashes when loading several large images at once. The updated implementation works well, but can be made more efficient:

Consider loading 10 8MP (3264x2448) images in 150x150 pixel containers. The target size (150x150) is larger than asset.thumbnail (approx 100x100), therefore the fullScreenImage representation is used instead (approx 1334x1000).

This commit will scale the asset to the minimum size required while taking into account original aspect ratio and device scale. Memory usage is considerably lower and many more images can be loaded in
sequence without having to worry
Closes https://github.com/facebook/react-native/pull/2008
