i would like to avoid that if possible. how are your brush strokes
different from masks? you need additional data in form of a displacement
vector? i guess this is where we have to face from a technical side that dt
isn't make for this kind of task.
you can always create a second instance of the module if you need more
parameter space.. (not very elegant, but workable).
