      Fix wrong conditions in isEmojiBase · 1934c2c3

      I computed ranges using low <= c || c <= high, should be &&.

      Suppress line breaks in emoji + modifier · 56840e80
      由 Raph Levien 提交于 
      An emoji base with an emoji modifier renders as a single glyph and
thus should not be a line break. Current (Unicode 8) logic does
indicate a line break, so we override the results of the ICU line
break iterator. The code references a proposal to improve Unicode
behavior; when that is adopted and we upgrade ICU accordingly, the
special-case code should be deleted, but the tests can remain.

      Use color font if skin tone is specified. · 0036da16
      由 Seigo Nonaka 提交于 
      If skin tone is specified, the base emoji should be emoji style even
if it is text presentation default emoji.

This patch also removes wrong test case which expects default emoji
presentation but it is controlled by family order in /etc/fonts.xml
and there is no special logic for default presentation in minikin.
Thus the default presentation unit test should not be in minikin.

      Suppress linebreaks in emoji ZWJ sequences · d3f45892
      由 Raph Levien 提交于 
      Due to the way emoji ZWJ sequences are defined, the ICU line breaking
algorithm determines that there are valid line breaks inside the
sequence. This patch suppresses these line breaks.

This is an adaptation of I225ebebc0f4186e4b8f48fee399c4a62b3f0218a
into the nyc-dev branch.

getOffsetForAdvance and line breaking.

      Disable hyphenation when word overlaps style boundary · aa736d00
      由 Raph Levien 提交于 
      In cases when a word (as defined by the ICU break iterator) overlaps a
style boundary, the returned wordStart can be extend before the range
currently being measured for layout. When we try to hyphenate the
resulting substrings, we get a negative range, which crashes. This
patch disables hyphenation in this case.

      Improve Paint.measureText and Paint.hasGlyph for variation sequences. · 6b1c227d
      由 Seigo Nonaka 提交于 
      Before this patch, the font fallback chain iterated all installed font
families if a variation selector was specified.

This CL narrows down the range of iteration.
To decide the font family for the variation sequence, we need to search
for both the variation sequence and its base code point.
The new range of the iteration is a union of them.

With this change, the running time of Paint.hasGlyph for the variation
sequence improves 50% and the running time of Paint.measureText for the
variation sequence improves 40% for the large text case on Nexus 6
userdebug.

      Refine hyphenation around punctuation · 57b6dae9
      由 Raph Levien 提交于 
      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.

      Improve Paint.hasGlyph performance by caching hb_font_t · 89e80237
      由 Seigo Nonaka 提交于 
      It turned out that hb_font_t creation is not a lightweight operation.
Especially, Paint.hasGlyph creates hb_font_t for all existing fonts
every time. To improve the performance, cache hb_font_t instead
of hb_face_t.

Note that to calculate horizontal advance, MinikinPaint needs to be
associated with hb_font_t by calling hb_font_set_funcs. With this patch,
hb_font_set_funcs may be called multiple times for the same hb_font_t
object. However this is not an issue since MinikinPaint is unique
during layout.
