Comment (by blobfolio):

 PHP support for WebP is starting to catch up. I'd like to investigate
 whether or not it is feasible to expand this enhancement to include
 thumbnail generation support as well.

 I'll dive deeper in the next week or so and update the patch accordingly,
 but in the meantime, here are a few references:

 GD and EXIF support:
  * https://php.net/manual/en/function.imagecreatefromwebp.php (PHP 5.5)
  * https://php.net/manual/en/function.imagewebp.php (PHP 5.5)
  * https://secure.php.net/manual/en/function.exif-imagetype.php (PHP 7.1)

 The output from `gd_info()` should include `['WebP Support']=>true` under
 environments that support WebP.

 Imagick can be compiled with WebP support (e.g. with `libwebp-dev`, etc.).
 This does not seem to be very common yet, but we could conditionally check
 the response of `Imagick::queryFormats('WEBP')`; a non-empty `array()`
 being Yay!, an empty one being Boo!
