5efd6300dc mv SharpYuvEstimate420Risk to extras/
There's no need for this in libsharpyuv currently. This avoids an ABI
bump and library size increase.

d7a0506dcc Add YUV420 riskiness metric.
Basic version for 8 bit only and C only (no simd).

Hidden behind a compile flag because the precompiled table is
fairly large (114kiB) and more than triples the size of the library.

639619ce72 cmake: fix dll exports
move WEBP_EXTERN definition from Makefile.vc to webp/types.h using the
existing WEBP_DLL define to control its declaration to
__declspec(dllexport); the same is done for SHARPYUV_EXTERN

93c54371 sharpyuv: add support for 10/12/16 bit rgb and 10/12 bit yuv.

a3b68c195e Build libsharpyuv as a full installable library.
Headers are installed in a "sharpyuv" subdirectory of the webp
dir, e.g. /usr/local/include/webp/sharpyuv/
Remove unnecessary dependency from sharpyuv to webp/types.h

Add SHARPYUV_EXTERN so that only symbols meant to be public
are exported.

Sharpyuv users can use the library with:

find_package(WebP)
if(TARGET WebP::sharpyuv)
  # ... use WebP::sharpyuv
endif()

10bit+ input is truncated to 10bits for now.

29cc95ce4c Basic version of libsharpyuv in libwebp, in C.
It's self contained apart from a dependency on src/webp/types.h and src/dsp/cpu.h
For now it's only set up as an internal library, not an installable one.
Webp doesn't depend on it yet, the code is only duplicated.
