Onion Skin mode is a great way for users to notice changes in the images that might be overlooked when you look at them side by side. By overlaying the new image on top of the old image, the users can change the opacity to see the transition that were made.
The following features are included in this mode:
- Scale the new image to the same size as the old image
- Changing the opacity of the top image

Inside your image-diff repo, run polymer serve
to start a local web server and open localhost:8080/test
to view your tests. See here for more info.
Or run npm run wct-test
to run all your tests.
