- 4/2/2018: version 1.0.0
This is a binary compatible release.
* lossy encoder improvements to avoid chroma shifts in various circumstances
(issues #308, #340)
* big-endian fixes for decode, RGBA import and WebPPictureDistortion
Tool updates:
gifwebp, anim_diff - default duration behavior (<= 10ms) changed to match
web browsers, transcoding tools (issue #379)

the interpretation of a 0 duration depends on the implementation;
merging of multiple frames isn't guaranteed, some may enforce a minimum
duration.

this internalizes the init checks and provides stronger synchronization
with pthreads when available while still allowing VP8GetCPUInfo to be
modified (mostly for testing purposes). windows is left as is since a
critical section or mutex would cause a leak.

the 'accum' variable can be larger than 15b for large
rescale values.
Assert triggered:
src/dsp/rescaler_sse2.c:249: RescalerExportRowExpand_SSE2: Assertion `v >= 0 && v <= 255' failed.
src/dsp/rescaler_sse2.c:350: RescalerExportRowShrink_SSE2: Assertion `v >= 0 && v <= 255' failed.
-> fall back to C implementation in this case for now

Also fix the bug where near lossless was not used
and allow examples to be built by default.

this prevents unknown escapes containing '-'s getting stripped on OS X
when a tty targeted font is used
Change-Id: I11d77f2984d9fd67a8b22948fb21e4c11396aec4
This is to harmonize the -h/-version options on all our examples.
+ added GetAnimatedImageVersions() method to anim_util.*

Control Flow Integrity [1] indirect call checking verifies that function
pointers only call valid functions with a matching type signature. This
change eliminates function pointer casts that were causing cfi-icall
failures.

this is consistent with web browser behavior as well as various
transcoding tools (ffmpeg, gif2apng, etc).
also: update anim_diff to account for this new behaviour.
BUG=webp:379

Output is <.1% difference in size, randomly.
Speed is 30-50% faster (-m 0 -sharp_yuv).
It also gives the exact same output on ARM and x86, because floats
are no longer used.

this quiets a -Wclobbered warning on const has_alpha under gcc-7 and
brings the variables closer to their first use.
