Garrett McCullough 404d74bd1e update docs for Transforms
Summary:
Documentation change only.

Filled out the Transforms docs a little more to indicate which props are now deprecated and to provide some guidance on the transform array since some values are expected to be strings and some are numbers

Joe Rickerby fa147f02e5 Update overflow docstring to add note on Android
Summary:
The overflow: visible option does not work on Android. This just add a little note to the docs of that property to make that clear.

See #3198  and https://react-native.canny.io/feature-requests/p/add-overflow-support-to-android .

Make it clear that this property is unavailable on Android. We had to figure this out by trial and error when porting an existing codebase, a small note in the docs would be helpful!

I could not find how to build the website - I tried `cd website && npm install && node ./server/generate.js` but I'm getting an error (*JSDOC_ERROR: There are no input files to process.*). But it is such a small change I can't see how it would break the docs build!

This diff adds display:none support to React Native. This enables hiding components which still calling their render method and keeping them within the state of your application. This enables preserving state in a component even though the component is not visible. Previously this was often implemented by rendering a component off screen as a work around. See below playground for usage.

```
class Playground extends React.Component {
  render() {
    return (
      <View style={{width: '100%', height: '100%', flexDirection: 'row', backgroundColor: 'white'}}>
        <View style={{width: 100, height: 100, display: 'none', backgroundColor: 'red'}}/>
        <View style={{width: 100, height: 100, backgroundColor: 'blue'}}/>

Janic Duplessis 0ed31eb3d6 BREAKING - Improve JS transform validation, add tests
Summary:
This improves JS validations of the transform object and makes it a bit stricter (hence the breaking change). When moving transform objects parsing to native (#10658) the validations got out of sync a bit, this makes sure JS validations are the same or stricter than the native ones to make sure we get consistent errors across platforms.

See #12110 for an example of an error that now gets caught by JS validations.

Also added snapshot tests for the errors to make sure `processTransform` throws when passing invalid values. It only tests the validation since the object parsing is now done natively for iOS and Android.

**Test plan**
Test that there are no errors in UIExplorer
Run new unit tests

Brent Vatne 346858a552 Add StyleSheet.setStyleAttributePreprocessor
Summary:
**Motivation**

On Exponent we load fonts dynamically and assign their native names by appending a session id, so that fonts from one Exponent "experience" do not clash with each other. So, before sending the `fontFamily` to native, we want to change it to the Exponent-scoped `fontFamily`.

Example:

```js
// Before rendering your app
StyleSheet.setStyleAttributePreprocessor('fontFamily', _processFontFamily);

function _processFontFamily(name) {
  // Pass system fonts through
  if (!name || Constants.systemFonts.indexOf(name) >= 0) {
    return name;
  }

  if (!Font.isLoaded(name)) {
    if (__DEV__) {
      console.error(`${name} is not a system font and has not been loaded through Exponent.Font.loadAsync. If you intended to use a system font, make sure you typed the name correctly and that it is supported by the current operating system. If this is a custom font, be sure to load it with Exponent.Font.loadAsync`);

Emil Sjolander 0a9b6bedb3 BREAKING - Fix unconstraint sizing in main axis
Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.

This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

Krzysztof Magiera 68b9a36858 Accept transforms list instead of matrix for transform view parameter.
Summary:
In #7916 I moved transform matrix decomposition logic from JS to java. The next step is to accept list of transforms instead oftransform matrix as a transform ReactProp. This way there is no extra processing required on JS side for the transform param (at least for android now) and this on the other hand allow us to execute transform updates (through offloaded animation) solely on the UI thread.

After this change there is a whole bunch of stuff from `Libraries/Utilities/MatrixMath.js` that can be deleted (methods like: determinant, inverse, transpose). Although astreet mentioned under one of my previous commits that the code is still being referenced internally at fb, so I decided not to delete it here.

**Test plan (required)**
Run UIExplorer Transform example before and after - compare the results
Run android unit test: com.facebook.react.uimanager.MatrixMathHelperTest

Paul O’Shannessy 5db5ee9f55 Upgrade to React v15.3.0-rc.2
Summary:
There were several fixes to how calls to propType checkers. This is to
account for the new deprecation warning - React.PropTypes will not be
part of production builds in the future.

Note: There is still a warning about an invalid argument to `React.PropTypes.oneOf` (React is running that validation sooner now). Specifically [both of these](b1e49832ef/Libraries/Components/Touchable/TouchableWithoutFeedback.js (L44-L45)) because `View.AccessibilityTraits` is actually undefined in tests (didn't look into why you conditionally set that).

**Test plan (required)**

`npm test` & fixed all warnings due to proptype secret

Brent Vatne a564af853f Throw flow error when trying to access a style that is not defined on a stylesheet
Summary:
I thought it would be useful to help clear out references to no longer used styles and also catch typos on style names to have flow error when we try to access a style that isn't defined.

Example:

```javascript
export default class AuthenticationScreen extends React.Component {
  render() {
    // This throws an error because `continer` is misspelled
    return (
      <View style={styles.continer} />
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
}
```

```javascript
export default class AuthenticationScreen extends React.Component {
  render() {
    // This throws an error because no fancyContainer style is defined
    return (
      <View style={[styles.container, styles.fancyContainer]} />
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
  },
}
```
