Comment (by blobfolio):

 Replying to [comment:167 adamsilverstein]:
 > @blobfolio - @flixos90 on the PR asked about the two sections of code
 that extract WebP info from the file directly
 (https://github.com/WordPress/wordpress-develop/pull/1137/files#r617747316
 & https://github.com/WordPress/wordpress-
 develop/pull/1137/files#r617745292). I'd like to add a doc block
 explaining/referencing the approach. Can you provide some more details?
 Otherwise I'll go looking, thought I'd ask first though.

 Hey @adamsilverstein,

 This page lays out the RIFF container format specs:
 https://developers.google.com/speed/webp/docs/riff_container

 Of particular relevance are the
 https://developers.google.com/speed/webp/docs/riff_container#webp_file_header
 (file signature and subtype differentiation) and
 https://developers.google.com/speed/webp/docs/riff_container#extended_file_format
 sections (width, height, etc.).
