Summary: We have a use case in the development of our app, where we are rendering some HTML content in a web view. But this content comes from the back end, and varies in height. There are other components on the page, so it's not a full screen web view. We need to dynamically alter the web view height, to fit the HTML content without scrolling, and to push the non-web view content on the screen down.
The solution I came up with, was to use the _loadingFinish callback, to send the evaluation of the injectedJavaScript property back to the React Native side. In my example above, injecting 'document.getElement(elementId).offsetHeight' evaluates to the height of the element, with margins and borders applied, and once returned to the RN app, it can change the app state and cause the web view height to be adjusted.

Summary: public
This has been broken for a while. The styles in the JS were being set on the container instead of the activity view itself.
Also, due to the way frames were set directly on layer properties instead of the view, resizing didn't work properly because the UIImageView inside the UIActivityView was not being realligned when the bounds changed. This also caused problems for other controls such as maps, where it was fixed with a method override, but the simpler solution is just to set the view center and bounds directly.

Summary: @public
This diff implements inline image support for <Text> nodes. Images are specified using <Image> tags, however all properties of the image are currently ignored apart from the source (including width/height styles).
Images are loaded asyncronously, and will trigger a text re-layout when they have loaded.

Summary:
Currently, the system for mapping JS event handlers to blocks is quite clean on the JS side, but is clunky on the native side. The event property is passed as a boolean, which can then be checked by the native side, and if true, the native side is supposed to send an event via the event dispatcher.
This diff adds the facility to declare the property as a block instead. This means that the event side can simply call the block, and it will automatically send the event. Because the blocks for bubbling and direct events are named differently, we can also use this to generate the event registration data and get rid of the arrays of event names.
The name of the event is inferred from the property name, which means that the property for an event called "load" must be called `onLoad` or the mapping won't work. This can be optionally remapped to a different property name on the view itself if necessary, e.g.
RCT_REMAP_VIEW_PROPERTY(onLoad, loadEventBlock, RCTDirectEventBlock)
If you don't want to use this mechanism then for now it is still possible to declare the property as a BOOL instead and use the old mechanism (this approach is now deprecated however, and may eventually be removed altogether).
Summary:
`view.screen` can be nil if the view has not yet been added to the view hierarchy (e.g. new view), so we should use `[UIScreen mainScreen]` instead.
In the future, if we need to support multiple screens, one possible fix is to set the rasterization scale in didMoveToWindow/Superview. For now we have just one screen, though.

Summary:
This diff removes calls to `-updateClippedSubviews` by only re-clipping when the scroll view moves by a certain number of pixels.
leeway = 50pt => 46.9% of calls removed
leeway = 10pt => 13.2% " " "
Summary:
Our events all follow a common pattern, so there's no good reason why the configuration should be so verbose. This diff eliminates that redundancy, and gives us the freedom to simplify the underlying mechanism in future without further churning the call sites.
Summary:
Moved the view creation & property binding logic out of RCTUIManager into a separate RCTComponentData class - this follows the pattern used with the bridge.
I've also updated the property binding to use pre-allocated blocks for setting the values, which is more efficient than the previous system that re-contructed the selectors each time it was called. This should improve view update performance significantly.
Summary:
The bridge implementation on React Android does not currently support boxed numeric/boolean types (the equivalent of NSNumber arguments on iOS), nor does Java support Objective-C's nil messaging system that transparently casts nil to zero, false, etc for primitive types.
To avoid platform incompatibilities, we now treat all primitive arguments as non-nullable rather than silently converting NSNull -> nil -> 0/false.
We also now enforce that NSNumber * objects must be explicitly marked as `nonnull` (this restriction may be lifted in future if/when Android supports boxed numbers).
Other object types are still assumed to be nullable unless specifically annotated with `nonnull`.
Summary:
By default, the edges of rotated layers on iOS have jagged edges because they are not antialiased. Setting `allowsEdgeAntialiasing` makes them look a lot nicer by smoothing out the jaggies. This is particularly important for UIs like Tinder cards, for example.

Summary:
RCTCache had really bad insertion performance when the cache was full due to having to LRU-sort the entries. This was making color
animations very slow.
I've fixed this in two ways:
1) by removing the sort and doing a linear search to remove old entries, which changes insertion perf to O(n) in the worst case instead of O(n log n) or even (n2).
2) by reducing the size of the color cache to 128 from 1024, which should be fine for normal use, without penalising animation performance.
Separately, border colors were not being retained, which caused crashes when the color cache was cleared. I've fixed that by retaining the border colors inside RCTView.
