fix(nodes): paste_image, paste mask operation doesn't want a black backdrop, black should translate to transparent, the hack here is to used the reference image instead, thus, acting as transparent but it's not. + img_scale, add "multiple of" for convenience

There was a problem hiding this comment.
This seems off. We are assigning new_image to temp_image. They now both refer to the same object. Then we paste image onto temp_image. Finally, we do an alpha composite of new_image and temp_image - so alpha compositing the same image onto itself?
I think I understand the root issue you want to address, but if you can provide some example input images to test with, I'd be better able to review. Ty

Summary
fix(nodes): paste_image, paste mask operation doesn't want a black backdrop. Black should translate to transparent and the hack here is to used the reference image instead. Thus, acting as transparent but it's technically not. + img_scale, add "multiple of" for convenience
