This API is just a boolean property that tells the hardware renderer
whether it should use mipmap levels.

The ANDROID_LARGE_MEMORY_DEVICE flag is not set for x86 platforms but it
is required to get animated GIF working. 256MB is considered "large".

  Fix access to freed memory

Source should be freed after all jpeg operations completed
since it is used by these operations.

It looks like Id8c91ae0be6cad8a7ef77a0cd5803676290986c1 upgraded this
message from an actual error notification into a full-fledged adb log
spammer. Oops! This CL moves it back to the location it should be at,
and requires SK_DEBUG to see it even there.

Android/Skia supports pre-multiplied Alpha. WebP image format supports
Alpha via color modes MODE_RGBA & MODE_RGBA_4444 (corresponding ones for
premultiplied alpha are MODE_rgbA & MODE_rgbA_4444).
The pre-requisite change for this one is the libwebp patch:

Cherry-pick Id8c91ae0be6cad8a7ef77a0cd5803676290986c1 from master.

During font initialization, create a seperate fallback list for each
locale. At runtime, use the fallbacklist associated with the locale
set in the paint object. Fallback files are associated with locales in
fallback_fonts.xml. Multiple files can be associated with the same
locale, ordering within that langauge and apart from that language in
the fallback order is preserved.

This changelist also includes some refactoring, notably of the
functions that call getNextContext().

When browsing JPEG image and then exiting Gallery, the TOMBSTONE issue
occour. This is because JPEG Decode method still access a pointer which has been deleted.
This patch can fix it.

Change-Id: Ia62ca8b048a34639d11f7838b03c74420b3b3868

The underlying problem is that no SkScalerContext objects existed at the
time shapeFontRun is called immediately after a locale change from en to
ja (apparently the dumping of the cache caused all these to be
deallocated), so gFTLibrary was null (and the call tio ref_ft_face
assumes that it's initialized).

There's a pattern for calls which might not necessarily be called from a
scaler context (GetAdvancedTypefaceMetrics is one such), to explicitly
check for an uninitialized library, and create one for the length of the
call if so. This patch changes GetUnitsPerEm to follow this pattern.

  Reduce embolden effect. DO NOT MERGE

Cherry-pick of Iec1c478171e33751be1cddbaae6a8ec30bb6cbab

Certain CJK glyphs become essentially unreadable when emboldened at
sizes used by common apps like News/Weather. Reducing embolden
strength slightly makes these glyphs much more readable without
sacrificing bold/normal weight differentiation.

The advance values computed by generateAdvance() were inconsistent with
those computed by generateMetrics, because the fMatrix22 was being
applied in the latter but not former case. Since fMatrix22.xx is 1.0
almost all the time (the exception is only when skew and scale are both
applied), failures were rare.

This patch is an alternative to ag/#/c/207887, in that they both fix the
problem, but in different ways. That patch made fMatrix22.xx equal to
1.0 in almost all cases, while this one gives correct advance values
for arbitrary fMatrix22 values.

After this checkin, SkCreateTypefaceForScript refs each typeface
that it creates before it returns it.  Additionally, all supported harfbuzz
codepoints are added to the unicode mapping array.  This patch also fixes a test crash (see bug)
