Here these mappings are used to convert from uppercase to lowercase,
and mk_hyb_file.py doesn't handle multi-character uppercase sequences.
Therefore, in case the sequence ßSS is encountered in a .chr.txt,
replace it internally with ßẞ.

minikin_tests was copying its test data to
$OUT/data/DATA/nativetest/minikin_test, and then packaging that with
LOCAL_PICKUP_FILES=$OUT/data/DATA, which would also pick up anything
any other module copyied to $OUT/data/DATA. $OUT/data/DATA isn't
where the tests expect to find their data, they look in
/data/nativetest/minikin_test. Copy the files to the intermediates
directory instead.
A future change will install LOCAL_PICKUP_FILES for local builds
to the correct place, so adb sync and
adb shell /data/nativetest/minikin_tests/minikin_tests will run the
tests.

These modules can be named the same between the target and host
libraries, which simplifies references to them, particularly in
Soong.
To prevent accidentally loading the system copy of the library,
we still rename the installed name to be libicu*-host.so. But
modules do not need to know that in order to build against them.

Unicode recommends that the zwj sequences should be emoji presentation
even if they don't have the proper U+FE0F. Thus always lookup the glyph

This CL fixes following test cases in minikin_tests
- FontFamilyTest.hasVariationSelectorTest
- HbFontCacheTest.getHbFontLockedTest
- HbFontCacheTest.purgeCacheTest
For the fix of FontFamilyTest.hasVariationSelectorTest, removing virtual
from GetUniqueId() in MinikinFont. After [1], MinikinFont's destructor
started calling purgeHbCache() which calls virtual method,
MinikinFont::GetUniqueId(). Fortunately, the SkTypeface::uniqueID()
returns just internal value, so we can store it at the construction time
and use it instead of calling SkTypeface::uniqueID() every time.
This patch also changes purgeHbFont to purgeHbFontLocked, as all uses of
it were already under global mutex. This change avoids deadlock on
explicit unref, as when invoked by a Java finalizer from the Java object
that holds a reference to the font.
Some of the tests needed to change to using the ref counting protocol
rather than explicitly destructing font objects, as well.

We changed the signature of the MinikinFont::GetTable method. This
patch updates the sample code, and fixes the build.
Change-Id: I1977be868bf7636986fc802915f3dd54c418a73a
The hb_font_t object holds on to tables of font data, acquired through
the MinikinFont::GetTable interface, which is based on copying data
into caller-owned buffers. Now that we're caching lots of hb_font_t's,
the cost of these buffers is significant.
This patch moves to a different interface, inspired by HarfBuzz's
hb_reference_table API, where the font can provide a pointer to the
actual font data (which will often be mmap'ed, so it doesn't even
consume physical RAM).

This patch eagerly purges the corresponding hb_font_t object from

Some fonts support multiple scripts, for example, some fonts for
Korean supports not only "Kore" but also "Jamo".
To select fonts based on their multiple languages, this CL introduces
the following changes:
- Compares all languages of the font family and use the maximum score
for font selection.
- Even if each language of the font family doesn't support the requested
language, the font get score of 2 if the requested font is covered by
all of the languages of the font family. For example, the font for
"ko-Hang,ko-Hani" gets score of 2 for the requested language "ko-Kore".

Indic combining marks, when combined with a common character such as
a hyphen or a dotted circle, used to get rendered in a different font
due to the greedy algorithm used in determining runs, which resulted
in the base character and the combining mark getting rendered in
separate font runs, resulting in a dotted circle appearing in phrases
such as "100-ാം" (0031 0030 0030 002D 0D3E 0D02).
This change makes combining marks change the font run of the base
character if the base character is supported in the same font as the
combining mark, similar to the support for emoji modifiers and the
combining keycap.

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.

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.

An emoji with a modifier should be treated as a single grapheme, i.e.
it should not be possible to place the cursor between the base and
modifier. This patch implements the proposed Rule GB9c from Mark
Davis's proposal entitled "Fixing breaking properties for emoji",
L2/16-011R3.
The patch also skips over variation sequences attached the to the
preceding character, for computing grapheme cluster boundaries.

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.

Recent changes have added special cases for line breaks within URLs
and email addresses. Such breaks are undesirable when they can be
avoided, but at other times are needed to avoid huge gaps, or indeed
to make the line fit at all.
This patch assigns a penalty for such breaks, equal to the hyphenation
penalty. The mechanism is currently very simple, but would be easy to
fine-tune based on more detailed information about break quality.

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.
