Comment:

 In [attachment:"35725.9.diff"]:

 * Create a mime type mapping object that maps image formats, so far jpegs
 are mapped to webp, meaning when you upload a jpeg image, the downsampled
 copies will be created as webp.
 * Introduce a new filter `image_editor_mime_mapping` which controls image
 format mapping; returning false will prevent remapping.


 In my testing, my resampled images where ~25% smaller than the jpeg
 versions. Other than the smaller file size, everything worked as expected.
 I am able to crop images, edit them in the media library and when I delete
 a jpeg image in the media library , the associated webp versions are also
 removed.
