Include visual prompting into SVG refactoring

[MischaPanch]

Refactoring is an important part of generation of variations and probably other downstream tasks. It is easy to get small things wrong, like fills or order of paths, which however completely change the visual appearance. A prompt a la:

"compare the render of the current status to what it is supposed to look like and fix the current one"

or even:

1. check if pixel perfect
2. describe the visual diff
3. refactor based on description

could help here and would also generally be an interesting/useful exploration.
