There was the possibility of stale indents from previous invocations persisting in the mLineWidths across multiple invocations. This patch clears them. Bug: 28090810 Change-Id: I3621dfbe983512046289373711709aeade52eab4

Implement a WordBreaker that defines our concept of valid word boundaries, customizing the ICU behavior. Currently, we suppress line breaks at soft hyphens (these are handled specially). Also, the new WordBreaker class has methods that determine the start and end of the word (punctuation stripped) for the purpose of hyphenation. This patch, in its current form, doesn't handle email addresses and URLs specially, but the WordBreaker class is the correct place to do so. Also, special case handling of hyphens and dashes is still done in LineBreaker, but all of that should be moved to WordBreaker.

Tuning for hyphenation parameters. We discourage hyphenation on the last line, but offset this penalty by also applying a penalty for each line, which optimizes for minimizing the number of lines. Thus, when hyphenation can reduce the number of lines, it increases the chance they're used. There's probably more tuning and refinement that can be done, but testing suggests that the tunable parameters are appropriate. Bug: 20883322 Change-Id: Ida7eaf8aced109e426694f5a386924a842d29c4b

Three hyphenation frequencies are now supported: kHyphenationFrequency_None, which turns off both automatic hyphenation and soft hyphens. kHyphenationFrequency_Normal, which has aconservative amount of hyphenation useful as a conservative default. kHyphenationFrequency_Full, which has a typographic-quality amount of hyphenation useful for running text and tight screens.

The name "margin" conflicts with another meaning, so we're making the name in the public api "idents" and the code consistent in naming. Change-Id: I9170116b4d972e4b25f0f319e78376310288eb41

In order to support layout in non-rectangular regions, the LineWidths object needs to accept an arbitrary array of margins. This is implemented in addition to the existing firstWidthLineCount/restWidth mechanism for convenience, though using only arrays would have the same expressive power.

This patch adds hyphenation using the Liang hyphenation algorithm, similar to TeX. It also improves the optimized line breaker so that it works correctly and efficiently even when the line width is not constant (there is a specialization for constant width, which is probably worthwhile, but performance TODOs remain). Still to be done: * hyphenator has many shortcuts, only tested with English * interaction between punctuation and hyphenation is problematic Change-Id: I2d94a1668ebc536398b7c43fcf486333eeb7c6aa

This patch adds a LineBreaker class to Minikin, which will be used for computing line breaks in StaticLayout. The version in this patch contains basically the same functionality that existed before, but hopefully better performance and an interface that's suitable for more sophisticated paragraph layout. Note that this version contains a high quality strategy, which mostly works but doesn't respect varying line width. Change-Id: I02485d58b1e52856296a72cdd4efd963bc572933
