Apple can bring in new users beyond Pixelmator's wildest dreams. This is definitely a product/talent acquisition. And Pixelmator has almost 2 decades worth of development already baked in, not sure how anyone can do it cheaper.
You're welcome but frankly I shouldn't do this nor should any one besides Apple. Apple has failed the community of PWM and temporal dithering sensitive individuals for almost a decade now, and hopefully this project can raise awareness and become additional proof against these technologies.
