Summary:The UICollectionView example is actually my use-case, which is discussed in a
bit more detail [here](https://github.com/alloy/ReactNativeExperiments/issues/2).
----
This is useful when wrapping native iOS components that determine their
own suggested size and which would be too hard/unnecessary to replicate
in the shadow view. For instance a `UICollectionView` that after layout
will update its `contentSize`, which could be used to suggest a size to
the shadow view.
The reason for adding it to -[RCTShadowView setFrame:] is mainly so it
can be used via the existing -[RCTUIManager setFrame:forView:] API and
because it might not be a feature you want to expose too prominently.
An origin of `{ NAN, NAN }` is used as a sentinel to indicate that the
frame should be used as a size suggestion. The size portion of the rect
may contain a `NAN` to skip that dimension or a suggested value for the
dimension which will be used if no explicit styling has been assigned.

Summary:The `uiBlockToAmendWithShadowViewRegistry:` is called on every single view manager, on every single layout pass. This causes all view managers to be eagerly intiialized, even if not being used.
In practice very few modules actually use this method, so by checking if the method is implemented before calling it, we can eliminate most of this work.
(Hopefully in future we can get ride of this method altogether, but right now it's integral to the way that text layout is implemented).

Summary:The bug is caused by a weird race condition. What happens is that when calling `UIRefreshControl#endRefreshing` the `UIScrollView` delegate `scrollViewDidScroll` function is called synchronously and then `dockClosestSectionHeader` crashes because the sticky header indexes are updated but not the contentView children.
I fixed it by adding an updating property on `RCTRefreshControl` and setting it before calling `endRefreshing` so we can know not to call `dockClosestSectionHeader` at that moment.
Tested with both `RefreshControl` and `onRefreshStart` prop.

Summary:New prop `hitSlop` allows extending the touch area of Touchable components. This makes it easier to touch small buttons without needing to change your styles.
It takes `top`, `bottom`, `left`, and `right` same as the `pressRetentionOffset` prop. When a touch is moved, `hitSlop` is combined with `pressRetentionOffset` to determine how far the touch can move off the button before deactivating the button.
On Android I had to add a new file `ids.xml` to generate a unique ID to use for the tag where I store the `hitSlop` state. The iOS side is more straightforward.

Summary:
RefreshControl did not start refreshing when refreshing was set to true initially. It also did not start refreshing on iOS when setting the prop from false to true without doing a pull to refresh gesture.
This was a pain in the ass to make work on iOS because UIRefreshControl seems super sensitive to when beginRefreshing can be called, for the initial render I need to call it in layoutSubviews. I also have to manually adjust the scrollview content offset when calling beginRefreshing. The code is a bit hacky but it was the only solution I found that was actually working.

When scrolling while RefreshControl is refreshing the sticky headers are offset by the height of the UIRefreshControl. This simply removes the height of the UIRefreshControl while it is refreshing and fixes the problem.
You can repro the bug using this example in UIExplorer by doing a pull to refresh and scrolling the ListView immediately after.

Summary:
I want to use the `RCTEvent` protocol for touch events as well. That's why I'm removing not very well defined `body` property and replacing it with `arguments` method, which will return an array that will be passed directly to the js call.
I think this makes sense because there is no unified arguments format for all events and and the called js method (`moduleDotMethod`) is already event specific.
This way touch events and scroll events can result in calling a completely different js function with a completely different arguments (what they indeed currently do).

Summary:

React Native currently exposes the iOS layer shadow properties more-or-less directly, however there are a number of problems with this:
1) Performance when using these properties is poor by default. That's because iOS calculates the shadow by getting the exact pixel mask of the view, including any tranlucent content, and all of its subviews, which is very CPU and GPU-intensive.
2) The iOS shadow properties do not match the syntax or semantics of the CSS box-shadow standard, and are unlikely to be possible to implement on Android.
3) We don't expose the `layer.shadowPath` property, which is crucial to getting good performance out of layer shadows.
This diff solves problem number 1) by implementing a default `shadowPath` that matches the view border for views with an opaque background. This improves the performance of shadows by optimizing for the common usage case. I've also reinstated background color propagation for views which have shadow props - this should help ensure that this best-case scenario occurs more often.
For views with an explicit transparent background, the shadow will continue to work as it did before ( `shadowPath` will be left unset, and the shadow will be derived exactly from the pixels of the view and its subviews). This is the worst-case path for performance, however, so you should avoid it unless absolutely necessary. **Support for this may be disabled by default in future, or dropped altogether.**
For translucent images, it is suggested that you bake the shadow into the image itself, or use another mechanism to pre-generate the shadow. For text shadows, you should use the textShadow properties, which work cross-platform and have much better performance.
Problem number 2) will be solved in a future diff, possibly by renaming the iOS shadowXXX properties to boxShadowXXX, and changing the syntax and semantics to match the CSS standards.
Problem number 3) is now mostly moot, since we generate the shadowPath automatically. In future, we may provide an iOS-specific prop to set the path explicitly if there's a demand for more precise control of the shadow.

Summary:
public
Blending semitransparent pixels against their background is fairly a fairly expensive operation on mobile GPUs. To reduce blending, React Native has a system called "background color propagation", where the background color of parent views is automatically inherited by child views unless explicitly overridden. This means that translucent pixels can be blended directly against a known background color, avoiding the need to do this dynamically on the GPU.
In practice, this is only useful for views that do their own drawing, which is basically just `<Image/>` and `<Text/>` components, and for image components it only really matters when the image has an alpha component.
The automatic background propagation is a bit of a hack, and often does the wrong thing - for example if a view overflows its bounds, or if it overlaps a sibling, the background color will often be incorrect and need to be manually disabled. Because the only place that it provides a significant performance benefit is for text, this diff disables the behavior for everything except `<Text/>` nodes. It might still be useful for `<Image/>` nodes too, but looking through the examples in UIExplorer, the number of places where it does the wrong thing for images outnumbers the cases where it provides significant reduction in blending.
Note that this diff does not prevent you from eliminating blending on image components by manually setting an opaque background color, nor does it stop you from disabling color propagation on text components by manually setting a transparent background.

Summary:
Both iOS and Android currently support some sort of native pull to refresh control but the API was very different. I tried implementing a component based on PullToRefreshViewAndroid but that works on both platforms.
I liked the idea of wrapping the ListView or ScrollView with the PullToRefreshView component and allow styling the refresh view with platform specific props if needed. I also like the fact that 'refreshing' is a controlled prop so there is no need to keep a ref to the component or to the stopRefreshing function.
It is a pretty rough start so I'm looking for feedback and ideas to improve on the API before cleaning up everything.
On iOS we could probably deprecate the onRefreshStart property of the ScrollView and implement the native stuff in a PullToRefreshViewManager. We could then add props to customize the look of the UIRefreshControl (tintColor). We could also deprecate the Android only component and remove it later.
