[Feature Request]: Img2Img: Button to reset output dimensions to Source Image dimensions.

Is there an existing issue for this?

What would your feature do ?

I would like a button in Img2Img (as well as inpainting, perhaps this moreso) to reset the output dimensions to the dimensions of the Source Image. I don't always actually want to scale/crop the image in these UIs, and this would make that simpler (at this time, if I much with anything, I have to go back and inspect the original image to sort it all out).

An additional component to this feature that would be handy would be a "Lock Aspect Ratio" checkbox. The behaviour of which would be such that updating one dimension would automatically update the other to maintain the aspect ratio.

Proposed workflow

Programmatically: On focus of either dimension fields check if "Preserve Aspect Ratio" is checked, if so, calculate current aspect ration and bind a handler to field update to update the opposite field, if not, debind handler of bound, do nothing.

The Reload Source Dimensions button should bypass the update handler.

This looks like a purely JS issue, any one-shot guidance as to where to go to edit this? I'll make a PR.
