We use a weak approximation of this for hit testing. So awesome!

  Cool! If you're willing to share, I'm interested to hear how your approximation works. Do you just do fewer rounds? Do you use bigger step sizes?

    It's point picking for ~svg, where we draw a wider region than the actual elements and just go with that. The goal is not having to precisley click on small objects in a big scene. This generates a reverse index for knowing which element each pixel fuzzily refers to, and if far, if better described as blankspace. So, just 1 step, and we can cover a huge scene :)
