Add `I18nManager` API from React Native. This can be used to control
when the app displays in RTL mode.
Add `$noI18n` property suffix for properties that StyleSheet will
automatically flip. This can be used to opt-out of automatic flipping on
a per-declaration basis.
Scrolling is broken by the patch that adds ResponderEvent support for
multi-input devices: 6a9212df40
By calling 'preventDefault' on every touch event, scroll events were
cancelled. This patch shifts the responsibility for calling
'preventDefault' to the 'View' event handler normalizer, and only on
touch events within the Responder system.
Fix#175
Certain devices support both mouse and touch inputs. The Responder
plugin needs to support this. Previously it would specific touch-only
dependencies if touch support was detected.
The recommended way to prevent browsers firing mouse events after touch
events is to call `preventDefault` on the touch event. This may be
problematic if/when `View` and `Touchable` support URLs/hrefs.
Fix#169
View's default styles include `maxWidth:"100%"` to fix a specific
flexbox bug in Internet Explorer. But it's not needed for the default View
layout and it limits the width of absolutely positioned elements (a
bug).
First patch: 41159bcb10
@chriskjaer mentioned that changing from 'div' to 'span' introduces
different validation errors, e.g., <span><form>a</form></span>.
This patch uses 'context' to switch to a 'span' element if a 'View' is
being rendered within a 'button' element.
There are certain contexts where using a `div` is invalid HTML and may
cause rendering issues. Change the default element created by
`createReactDOMComponent` to a `span`.
**Appendix**
The following HTML results a validator error.
<!DOCTYPE html>
<head>
<meta charset="utf-8">
<title>test</title>
<button><div>a</div></button>
Error: Element `div` not allowed as child of element `button` in this
context.

This fixes several issues with 'StyleSheet' and simplifies the
implementation.
1. The generated style sheet could render after an apps existing style
sheets, potentially overwriting certain 'html' and 'body' styles. To fix
this, the style sheet is now rendered first in the document head.
2. 'StyleSheet' didn't make it easy to render app shells on the server.
The prerendered style sheet would contain classnames that didn't apply
to the client-generated style sheet (in part because the class names
were not generated as a hash of the declaration). When the client
initialized, server-rendered parts of the page could become unstyled. To
fix this 'StyleSheet' uses inline styles by default and a few predefined
CSS rules where inline styles are not possible.
3. Even with the strategy of mapping declarations to unique CSS rules,
very large apps can produce very large style sheets. For example,
twitter.com would produce a gzipped style sheet ~30 KB. Issues related
to this are also alleviated by using inline styles.
4. 'StyleSheet' didn't really work unless you rendered an app using
'AppRegistry'. To fix this, 'StyleSheet' now handles injection of the
DOM style sheet.
Using inline styles doesn't appear to have any serious performance
problems compared to using single classes (ref #110).
