Summary:
Here's a little background. Resizing is inferior to scaling. See http://frescolib.org/docs/resizing-rotating.html#_
Currently, React Native has a heuristic to use resize when the image is likely to be from the device's camera. However, there may be other cases where a developer wants to use resize. For example, when the developer knows they'll be downloading a large image from a service but the image will be rendered at a small size on the device.
This change adds a `resizeMethod` prop to the `Image` component so developers can choose how Fresco resizes the image. The options are 'auto', 'resize', or 'scale'. When 'auto' is specified, a heuristic is used to choose between 'resize' and 'scale'. The default value is 'auto'.
**Test plan (required)**
In a small test app, verified that the `resizeMethod` prop properly influences the mechanism that is used to resize the image (e.g. resize or scale).

Summary:
I've seen quite a few newbs trip on this, so I'm fixing it.
First - you have to set the width/height on a remote image, otherwise nothing shows. This is [even on stack overflow](http://stackoverflow.com/questions/30091398/unable-to-display-image-with-react-native-with-uri).
Second - with the addition of ATS in iOS most people who copy/paste this example will not be able to load an insecure image, so I changed it to the `https`.
**RESULT** this doc becomes copy/paste friendly again for beginners.

Addresses this comment: https://github.com/facebook/react-native/issues/2296#issuecomment-232446493
This pull request adds the `center` value to `ImageResizeMode`.
When set, it will center the image within its frame.
If the image is larger than its frame, the image is downscaled while maintaining its aspect ratio.
That is how the Android implementation works, too.
Sorry, don't have time to write tests. 😢
Any reviewers should make sure `RCTTargetRect` returns the correct value when:
- the image is smaller than its frame (ie: no downscaling needed)
- the image is larger than its frame (should be downscaled to avoid clipping)

Summary:
This adds a new resize mode for iOS 'repeat' that tiles the image over it's frame. This allow to easily create a view with a repeating background pattern which there is no way to do at the moment without including a bunch of different sized assets.
I'm not 100% sure it should be a resizeMode or a separate prop but I went with resizeMode since it made more sense to me and the are not really any use cases where we'd want to use this with another resizeMode other than 'stretch'.
**Test plan**
Tested mainly by adding a UIExplorer example, also tested that changing the resizeMode prop from and to 'repeat' worked properly.
I'd like to implement this on Android too but it is a bit trickier since Fresco's ImageView doesn't support image tiling and would require submitting a PR there too :(

Now that we no longer have a separate NetworkImageView implementation, we can remove that code path from Image.js

Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:
```
<Image
style={styles.logo}
source={{
uri: 'http://facebook.github.io/react/img/logo_og.png',
headers: {
Authorization: 'someAuthToken'
}
}}
/>
```
Note that the header values must be strings.
Works on iOS and Android.
**Test plan (required)**
- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.
Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.
This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.
This commit also contains a change in `RCTShadowText.m`

`lineHeight`, `textAlign`, and `writingDirection` when they've actua

Summary:

This diff adds a `getSize()` method to `Image` to retrieve the width and height of an image prior to displaying it. This is useful when working with images from uncontrolled sources, and has been a much-requested feature.
In order to retrieve the image dimensions, the image may first need to be loaded or downloaded, after which it will be cached. This means that in principle you could use this method to preload images, however it is not optimized for that purpose, and may in future be implemented in a way that does not fully load/download the image data.
A fully supported way to preload images will be provided in a future diff.
The API (separate success and failure callbacks) is far from ideal, but until we agree on a unified standard, this was the most conventional way I could think of to implement it. If it returned a promise or something similar, it would be unique among all such APIS in the framework.
Please note that this has been a long time coming, in part due to much bikeshedding about what the API should look like, so while it's not unlikely that the API may change in future, I think having *some* way to do this is better than waiting until we can define the "perfect" way.

Summary:

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.
This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.
I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

Summary:
RCTNetworkImageView and RCTStaticImage had significant overlap in functionality, but each had a different subset of features and bugs.
This diff merges most of the functionality of RCTNetworkImageView into RCTStaticImage, eliminating some bugs in the former, such as constant redrawing when properties were changed.
I've also removed the onLoadAbort event for now (as it wasn't implemented), and renamed the other events to match the web specs for `<img>` and XHMLHttpRequest. The API is essentially what Adobe proposed here: http://blogs.adobe.com/webplatform/2012/01/13/html5-image-progress-events/
The following features have not yet been ported from RCTNetworkImageView:
- Background color compositing. It's not clear that this adds much value and it increases memory consumption, etc.
- Image request cancelling when images are removed from view. Again, it's not clear if this is a huge benefit, but if it is it should be combined with other optimisations, such as unloading offscreen images.
(Note that this only affects the open source fork. For now, internal apps will still use FBNetworkImageView for remote images.)
Summary:
This PR adds 4 native events to NetworkImage.
Using these events I could wrap `Image` component into something like:
```javascript
class NetworkImage extends React.Component {
getInitialState() {
return {
downloading: false,
progress: 0
}
}
render() {
var loader = this.state.downloading ?
<View style={this.props.loaderStyles}>
<ActivityIndicatorIOS animating={true} size={'large'} />
<Text style={{color: '#bbb'}}>{this.state.progress}%</Text>
</View>
:
null;
return <Image source={this.props.source}
onLoadStart={() => this.setState({downloading: true}) }
onLoaded={() => this.setState({downloading: false}) }
onLoadProgress={(e)=> this.setState({progress: Math.round(100 * e.nativeEvent.written / e.nativeEvent.total)});
onLoadError={(e)=> {
alert('the image cannot be downloaded because: ', JSON.stringify(e));
this.setState({downloading: false});
}}>
{loader}
</Image>
}
}
```
Useful on slow connections and server errors.
There are dozen lines of Objective C, which I don't have experience with. There are neither specific tests nor documentation yet. And I do realize that you're already working right now on better `<Image/>` (pipeline, new asset management, etc.). So this is basically a proof concept of events for images, and if this idea is not completely wrong I could improve it or help somehow.

Summary:
ActivityIndicator was forwarding all of its props except `style` to the inner native view. This meant that onLayout would report a zero-sized frame that was relative to the wrapper view instead of the parent of the ActivityIndicator.
This diff adds `onLayout` to the wrapper view instead of the native view.
In general, all components that forward props need to be audited in this manner.
