1b27bf8b WEBP_REDUCE_SIZE: disable all rescaler code
Change-Id: Id1b03256c4c04b8db31527e60cd31dd20ce6f3ad
- 11/24/2017: version 0.6.1
This is a binary compatible release.
* lossless performance and compression improvements + a new 'cruncher' mode
(-m 6 -q 100)
* ARM performance improvements with clang (15-20% w/ndk r15c, issue #339)
* webp-js: emscripten/webassembly based javascript decoder
* miscellaneous bug & build fixes (issue #329, #332, #343, #353, #360, #361,
#363)
Tool updates / additions:
added webpinfo - prints file format information (issue #330)
gif2webp - loop behavior modified to match Chrome M63+ (crbug.com/649264);
'-loop_compatibility' can be used for the old behavior

only supported ones are: RGBA/BGRA/rgbA/bgrA (decoder)
as well as: WebPPictureImportRGB/RGBX/RGBA (encoder).
(note: extras/get_disto is affected too)

this results in flickering with animated webp + alpha. disabling the
option is a workaround to restore the behavior to the previous release.
BUG=webp:365
Change-Id: Iac7fcc0d483837e76cc54ad3f26c4e0e5511e31d
remove auto-filter (-af) support and make WebPPictureCopy,
WebPPictureIsView, WebPPictureView, WebPPictureCrop, and
WebPPictureRescale noops.

with gcc-4.8, clang-4.0.1/5 this is no faster (actually up to 2x slower)
than the code generated for memset (0x01010... * dst[-1]). shuffles in
sse4 recover a bit, but performance is still down.
Change-Id: Ie85e8353f8ede559d0b05a1d388787fd18ecc80f
Rewrote WebPPictureHasTransparency() to use them (even for argb).
This is 10% faster, for some reasons.
SSE2 version should be straightforward.
Removes a TODO.

The WebPDemux and WebPAnimDecoder APIs are provided for the purpose of
animated webp parsing and decoding. No major changes are currently
planned for the libwebp API.

this can result in an alignment hint on arm causing a SIGBUS. casting
the input ptr to anything aside from its type is unnecessary for memcpy
and is contrary to the intent of this function.

when targeting NEON C functions with NEON equivalents won't be used, but
will contribute to binary size. the same goes for sse2, etc., but this
change is primarily concerned with binary sizes for android arm targets.
note '-noasm' or otherwise modifying VP8GetCPUInfo will have no effect
on the use of NEON functions.
this decision can be overridden by defining WEBP_DSP_OMIT_C_CODE to 0.
