GIMP -> Filters -> Animation -> Unoptimize

Is there a method in the API to convert all the frames to unoptimized frames so it is easier to edit them and not deal with strange animation sequence artifacts?

e.g. A method in which ALL (excluding the first) frames are converted full width/height dimensions and contain duplicate pixel RGBA values for any preceding layer where otherwise it may have been transparent with a combined disposal method, to be changed to replace disposal method, etc.

For example see: https://graphicdesign.stackexchange.com/questions/55311/how-can-i-modify-a-gif-that-uses-cumulative-layers

Also see: https://www.npmjs.com/package/imagemin-giflossy
unoptimize
```
Type: boolean
Default: false
```
Unoptimize GIF animations into an easy-to-edit form.
e.g.:
```
imageminGiflossy({ unoptimize: true });
```

edit/update: As a technicality, it is possible to create GIF images where the first frame/layer is not the full dimensions of the image.
