One more thing. I think the dithers of the two objects should be independent.

esheldon commented 2 years ago

how big? A pixel is significant for these object sizes

esheldon commented 2 years ago

I kept the separation constant and dithered the pair because a pixel sized dither would dramatically change the blending

Hmmmm ok. Let's keep it as is then. Thanks for the back and forth here!
