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.

Summary:
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:
This is a final diff in the stack, which makes us not send a bazillion events to js after it's been busy while an user dragged his finger on a screen (resulting in ~two events per frame).
I made "touchMove" event to be coalescable, which makes us not send anything while dragging (since this makes both scroll events and touch move events coalesced and not being send until either next js frame or the next different touch event occurs).
This change is far from perfect. The event name is a hard coded string and the coalescing works with some (reasonable) assumptions on internal structure of these touch events. Which may or may not be really true. It would be great if someone could comment on these.
I'm thinking about making the touches more strongly typed. Any thoughts on this?

Summary:
This diff finally makes touch events to be emitted to js from the same object as scroll events. Thanks to changes in previous diffs this means the js will now process them in the right order.
This diff on its own would cause us to send events to js on every frame while dragging a finger on the screen. This is something we tried to avoid with event coalescing in the past, and gets fixed in the following diff D2884595.

**This diff is part of a larger stack. This is a high level overview about what’s going on here.**
This stack of diffs fixes an issue where scroll events and touch events wouldn’t be processed in the correct order on js side.
Current state of world:
* touch events are send to js immediately when they happen (this makes js respond to touches as soon as possible)
* scroll events are buffered, coalesced and send at the beginning of each js frame (coalescing helps in a case where js is busy processing for several native frames and would get all scroll event for that period afterwards)
How did I change this?
1. I’ve made touch events go through the same class every other event (scroll events included) go, RCTEventDispatcher. This gives us a single place to handle all events.
2. I’ve changed RCTEventDispatcher to flush all buffered events every time it gets a touch event before dispatching the touch. This fixes the original ordering issue.
3. I’ve made “touchMove” behave the same way as scroll events do - they are buffered and coalesced. Since “touchMove” events are fired as often as scroll events (while you drag your finger around), doing only 2. would bring back the issue buffering was fixing.
All of this together effectively still keeps the order of events right, avoids overloading js in the important case we care about. The only downside is an increased latency for “touchMove” events, since they are to longer send to js immediately.
(Even better solution would be changing the native->js event passing system to be pull based instead of push based. That way js would always request touches that has happened since the last time it has asked, which would make it get them as soon as it’s possible to process them and native could do coalescing at that point.
However this change has a much bigger scope, so I’m going with this stack of diffs for now.)

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).

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

I did not realize that `[UIScreen mainScreen].nativeBounds` reports the *actual* resolution, not the virtual resolution, and was dividing by the virtual scale (3.0) instead of the actual native scale factor (2.6).
This only affects iPhone6+, because for all other iOS devices, the virtual resolution matches the native resolution.

Currently, AlertIOS has the following API:

I've changed the API to look like the following:

I know that breaking changes are a big deal, but I find the current alert API to be fairly inconsistent and unnecessarily confusing. I'll try to justify my changes one by one:
1. Currently `type` is an optional parameter of `alert`. However, the only reason to change the alert type from the default is in order to create one of the input dialogs (text, password or username/password). So we're in a weird state where if you want a normal text input, you use `prompt`, but if you want a password input you use `alert` with the 'secure-text' type. I've moved `type` to `prompt` so all text input is now done with `pro

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.
