img2img - new parameters for Loopback script (zoom, rotation, ...)

[MinottiAlessandro]

Hi everyone,
I'm trying to replicate something like:

• https://www.reddit.com/r/StableDiffusion/comments/yhoppz/pandoras_grand_vortex
• https://www.reddit.com/r/StableDiffusion/comments/yag8db/endless_war_animation

I didn't find a way to do this kind of things yet, so i thought it would be cool if in the Loopback script we could have some more parameters to control every input frame.
I was thinking about something like zoom in/out, rotation, translation x/y, a flag to automatically generate a video from the images and a multiline prompt (already discussed in #1453) that let us decide what prompt use starting from what frame.

Again I'm not completely sure if this is already possible, I hope this could be a cool idea for future developments :)
