Comment:

 Starting to investigate, this isn't trivial to implement and there are
 some UX issues to think about. I think we should treat it as a somewhat
 hidden progressive enhancement - if you drag an image in and you can
 upload it'll open the media modal and let you go through the process, but
 we can't cleanly display upload or permissions errors here.

 I'm attempting to adapt the code from the media library. I started with
 `tmpl-uploader-inline` in `wp-includes/media-template.php`, but working
 through it I don't think we should add any of that markup, only the JS
 should work (keeping the UI simple). I'm also looking at the
 `UploaderWindow` view in `wp-includes/js/media-views.js`. Need to
 investigate `wp.Uploader` next; work in progress patch is uploaded (if
 anyone else wants to iterate, please do so, otherwise I'll revisit likely
 in a couple weeks).
