 In ticket:35725 we added core support for the WebP image format. On the
 ticket, we discussed studying the best compression level ("quality")
 setting to use for WebP images
 ([https://core.trac.wordpress.org/ticket/35725#comment:152 comment 152],
 [https://core.trac.wordpress.org/ticket/35725#comment:124 comment 124],
 [https://core.trac.wordpress.org/ticket/35725#comment:117 comment 117],
 [https://core.trac.wordpress.org/ticket/35725#comment:101 comment 101]).
 In the end we decided to use the same default quality as JPEG images use
 for our initial pass.

 However, given the differences between the formats (and in anticipation of
 even newer formats), we should consider what the best default quality
 setting would be for WebP images.

 Some details on how we can test compression settings and arrive at an
 ideal level are [https://developers.google.com/speed/webp/docs/webp_study
 outlined in this post].
