Summary:
Issue [#2088](https://github.com/facebook/react-native/issues/2088).
The basic desire is to have a declarative mechanism to transform text content to uppercase or lowercase or titlecase ("capitalized").
My test plan involves having added a test-case to the RNTester app within the `<Text>` component area. I then manually verified that the rendered content met my expectation.
Here is the markup that exercises my enhancement:
```
<View>
<Text style={{ textTransform: 'uppercase'}}>
This text should be uppercased.
</Text>
<Text style={{ textTransform: 'lowercase'}}>
This TEXT SHOULD be lowercased.
</Text>
<Text style={{ textTransform: 'capitalize'}}>
This text should be CAPITALIZED.
</Text>
<Text style={{ textTransform: 'capitalize'}}>
Mixed:{' '}
<Text style={{ textTransform: 'uppercase'}}>
uppercase{' '}
</Text>
<Text style={{ textTransform: 'lowercase'}}>
LoWeRcAsE{' '}
</Text>
<Text style={{ textTransform: 'capitalize'}}>
capitalize each word
</Text>
</Text>
</View>
```
And here is a screenshot of the result:

Summary:
This is a complete rewrite of RCTText, the part of React Native which manages Text and TextInput components.
Key points:
* It's understandable now. It follows a simple architectural pattern, and it's easy to debug and iterate. Text flow layout is a first-class citizen in React Native layout system now, not just a wired special case. It also brings entirely new possibilities such as nested interleaving <Text> and <View> components.
* All <Text>-specific APIs were removed from UIManager and co (it's about ~16 public methods which were used exclusively only by <Text>).
* It relies on new Yoga measurement/cloning API and on-dirty handler. So, it removes built-in dirty propagation subsystem from RN completely.
* It caches string fragments properly and granularly on a per-node basis which makes updating text-containing components more performant.
* It does not instantiate UIView for virtual components which reduces memory utilization.
* It drastically improves <TextInput> capabilities (e.g. rich text inside single line <TextInput> is now supported).
