The distance code read from the bitstream is reduced by 1 before doing
the lookup. The prose describing the lookup was correct, the pseudocode
failed to subtract 1 and used x/y instead of xi/yi from the lookup.

Rather than make a copy, requiring an additional lock/unlock only to set
the pointer to itself, pass the address of SharpYuvGetCPUInfo and use it
as a sentinel to avoid updating the pointer.

This gives a similar structure to libwebp and fixes a bug where passing
NULL to SharpYuvInit() would unconditionally set optimized function
pointers. SharpYuvInit() is left as an undocumented public function and
SharpYuvGetCPUInfo is kept private to serialize updates to the pointer.

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.

CMake Error at WebPTargets.cmake:76 (set_target_properties):
The link interface of target "WebP::webp" contains:
Threads::Threads

* There is a typo in the target name.
* A find_package call is missing for an IMPORTED target.
* An ALIAS target is missing.

`add_definitions` has been superseded by `add_compile_options` and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`.

using the defaults present in 0.6.13 and setting

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