Note that the previous setting implemented at the time (`Noise multiplier for img2img`) technically achieves the same effect, but as noted in the name *only* applies to img2img (not hires fix), and due to how that parameter functions it is very sensitive, realisticly only useful in a range of `1` to `1.1`. For almost all operations it would be suggested to use the new `Extra noise` parameter instead.

For developers, a callback also exists (`on_extra_noise`). Here is an example of use that makes the region to add noise to maskable. https://gist.github.com/catboxanon/69ce64e0389fa803d26dc59bb444af53
