We could benefit from something like a "FormArray" ... which would be not part of Morphic?

Now the change you made is in AnimatedImageMorph, so way past the gif. How do we pass this image composition on? Create altered forms with the background or previous pixels filled in, or support the same composition in the morph? Somehow this couples the image format decoding and the morph implementation...

I don't really understand the reader code so I guess I'll pass on that.

This is interesting! Looks like you can control this mode of compression via so-called "graphics extension blocks". Maybe we should respect this directly in the GIF reader?

Ah you mean first image is opaque, then following ones use transparency for non moving parts?

Look at this gif:
Try toggling transparency on and off in the menu

I don't understand. I thought most gifs used transparency for transparency and compression is independent from that.

Most GIFs use transparenty for compression. So the general use case is that you want it opaque. You can turn off transparency in the menu
