- 12/17/2015: version 0.5.0
* miscellaneous bug & build fixes (issues #234, #258, #274, #275, #278)
* encoder & decoder speed-ups on x86/ARM/MIPS for lossy & lossless
- note! YUV->RGB conversion was sped-up, but the results will be slightly
different from previous releases
* various lossless encoder improvements
* gif2webp improvements, -min_size option added
* tools fully support input from stdin and output to stdout (issue #168)
* New WebPAnimEncoder API for creating animations
* New WebPAnimDecoder API for decoding animations
* other API changes:
- libwebp:
WebPPictureSmartARGBToYUVA() (-pre 4 in cwebp)
WebPConfig::exact (-exact in cwebp; -alpha_cleanup is now the default)
WebPConfig::near_lossless (-near_lossless in cwebp)
WebPFree() (free'ing webp allocated memory in other languages)
WebPConfigLosslessPreset()
WebPMemoryWriterClear()
- libwebpdemux: removed experimental fragment related fields and functions
- libwebpmux: WebPMuxSetCanvasSize()
* new libwebpextras library with some uncommon import functions:
WebPImportGray/WebPImportRGB565/WebPImportRGB4444

Sync-patch with libwebp ver 0.4.1-rc1 (change#I5346984d2).
- NEON assembly optimizations:
- ~25% faster lossy decode / encode (-m 4)
- ~10% faster lossless decode
- ~5-10% faster lossless encode (-m 3/4)
- Arch64 (arm64) & MIPS support/optimizations.

Updated the libwebp with the release 0.4.0-rc1 (change#I22be12d8).

Build & Ran following tests for Nexus N7 (Razor)
runtest --path cts/tests/tests/graphics/src/android/graphics/cts/BitmapTest.java
runtest --path cts/tests/tests/graphics/src/android/graphics/cts/BitmapFactoryTest.java
runtest --path cts/tests/tests/graphics/src/android/graphics/cts/BitmapRegionDecoderTest.java
runtest --path cts/tests/tests/graphics/src/android/graphics/cts/Bitmap_CompressFormatTest.java

runtest --path cts/tests/tests/graphics/src/android/graphics/cts/BitmapFactory_OptionsTest.java
runtest --path cts/tests/tests/graphics/src/android/graphics/cts/BitmapShaderTest.java

Also did the full Android build for following targets:
- flo
- grouper
- mako
- x86

Before this change is submitted, need to submit the change for cts/tests to update the threshold for WebP encoding for color-mode RGB565.

Added three color-spaces viz ARGB_8888, RGBA_4444, RGB_565 supported by
Android.
- Mentioned the WebP head change#Ia53f845b
(https://review.webmproject.org/#change,2650)
- Changed the color-mode ARGB_4444 to RGBA_4444 (this is the actual one
used in Skia).
- Fixed one bug (4 bit overflow) with RGBA_4444 mode.
