Two new nodes. Edit Lock sits between the model and the sampler, reads
what the edit changes from the model's own prediction at every step, and
puts the original back everywhere else. Edit Lock Restore swaps the
original's pixels in for those parts after the decode.
The zoom and shift a model adds to the whole picture are measured and
discounted before anything is compared, and an even tint is taken out.
An edit of the whole picture is left alone.
On MiniMax-H3-Image at 4 megapixels, 18 local edits at two seeds each
moved by up to 14.5 px plain and by 0.12 px or less locked.
