change_scene cuts the character out of a handed picture (inspyrenet-rembg),
inverts it and redraws only the rest at denoise 1.0 from the prompt's new
scene; GrowMask lets 6 px of the edge be redrawn for the seam. Tried on an
RTX 4050 6 GB with SDXL (Illustrious) 832x1216: about 30 s, the character
kept, the forest replaced by a night street.
A picture handed to a block may be written "name.png [output]" as Load
Image shows it. Two block descriptions are shorter so begin_task stays
under 4000 characters.
