 > @mikeschroder - The latest patch should do this when Imagick is present;
 GD currently cannot generate lossless WebP images.

 That's awesome; thank you! I'll give that a test.

 As an update, I'm still figuring out the best way to do DSSIM testing,
 because the tool used in the previous tests does not support WebP. It
 looks like this can be done with a user script + ImageMagick, but I've got
 to find out if the numbers generated can be compared to the previous ones,
 or whether that'll have to start from scratch.

 If anyone has thoughts / previous testing with DSSIM and WebP, insight and
 recs would be appreciated!

 One note on the new patch -- the WebP specific functions/sub-functions for
 gathering size/meta are starting to get a little confusing for me to
 follow. I'm wondering if it might be helpful to consolidate a little bit?
 I'm guessing it's this way for a reason, but figured I'd pass on the
 feedback.
