clarify that the data is after the size specified by the file size in
the header; an alternate way to read the previous statement was that the
data was after the 'WEBP' fourcc.

GLUT_glut_LIBRARY is a cache variable that is not recommended for use:
from cmake-3.24/Modules/FindGLUT.cmake:
This module may set the following variables depending on platform.
These variables may optionally be set to help this module find the
correct files, but clients should not use these as results:
...
``GLUT_glut_LIBRARY``
The full path to the glut library.

when WEBP_USE_THREAD=1; this is necessary after:
0d1b9bc4 WEBP_DEP_LIBRARIES: use Threads::Threads
fixes:
CMake Error at WebPTargets.cmake:76 (set_target_properties):
The link interface of target "WebP::webp" contains:
Threads::Threads
but the target was not found. Possible reasons include:
* There is a typo in the target name.
* A find_package call is missing for an IMPORTED target.
* An ALIAS target is missing.

since:
bfad7ab5 CMakeLists.txt: correct libwebpmux name in WebPConfig.cmake
replace list(TRANSFORM ...) with string(REGEX REPLACE ...); the former
was added in 3.12, but currently 3.7 is supported

`add_definitions` has been superseded by `add_compile_options` and
options added via `add_definitions` can have surprising behavior,
particularly when including `libwebp` as a sub-project via
`FetchContent`.
Change-Id: Icb8478dc92017576028becfd92c4567b4095fa60
using the defaults present in 0.6.13 and setting
--first-comment-is-literal to avoid reflowing the copyright block and
--max-subgroups-hwrap 3 (default is 2) to avoid making some short set()
statements multi-line.

this matches the behavior in autoconf and avoids expanding the ${var}
references in the files; the .pc files now match the autoconf install.

* changes:
picture_csp_enc.c: remove SafeInitSharpYuv
sharpyuv: prefer webp/types.h
sharpyuv,SharpYuvInit: add mutex protection when available
sharyuv_{neon,sse2}.c: merge WEBP_USE_* sections
add a few missing <stddef.h> includes for NULL
sharpyuv.h: remove <inttypes.h>
thread safety was internalized in:
782ed48c sharpyuv,SharpYuvInit: add mutex protection when available
Change-Id: I2877e7bb78bf89ad7504c33d04b22952c0c0a968
this provides better compatibility for older Visual Studio versions;
stdint.h is a part of C99.
this is consistent with the core libwebp library:
8fbb9188 prefer webp/types.h over stdint.h
Change-Id: I777cad70d9a407646c4193db9ca0f09e65d88735
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
Change-Id: Iecea360305bdd19a878255470a00b9dcc344c730
this is similar to WEBP_DSP_INIT and avoids the potential for a race in
initializing the function pointers and gamma table
Change-Id: I15af7d1a3e92c42eaa735751ca33eba0d1e83283
this hasn't been needed since:
93c54371 sharpyuv: add support for 10/12/16 bit rgb and 10/12 bit yuv.
Change-Id: I02051e8b576d7fd27824e13be0d087dc4e18209e
the ternary used with alpha_offset was removed in:
3b07d327 Import,RGBA: fix for BigEndian import
use the ALPHA_OFFSET directly

this localizes the conversion to int in the function; the parameter was
previously changed in:
6ab496ed fix some 'unsigned integer overflow' warnings in ubsan
implicit conversion from type 'uint32_t' (aka 'unsigned int') of value
2350919223 (32-bit, unsigned) to type 'int' changed the value to
-1944048073 (32-bit, signed)

Change-Id: I589eec11c0dabaeba99e153e705f956181c570d2
in TransformColorBlue; make new_blue an int to avoid:
implicit conversion from type 'int' of value 264 (32-bit, signed) to
type 'uint8_t' (aka 'unsigned char') changed the value to 8 (8-bit,
unsigned)

Change-Id: Ife276a59231075788396204e1a192f3b0c6d9e21
add explicit casts in calls to ColorTransformDelta()
clears warnings of the form:
implicit conversion from type 'uint8_t' (aka 'unsigned char') of value
254 (8-bit, unsigned) to type 'int8_t' (aka 'signed char') changed the
value to -2 (8-bit, signed)
