It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Is it still 1.56% if you increase the radius size? I would think that the contribution %age would go way down at that radius.

I didn't measure it, that's from the article on the lerp hack. I think it's probably still a good rule of thumb, it obviously isn't going to be exact for every radius.

I updated the comment to reflect it isn't exactly 1.56%

I'm having a hard time getting this through CI. I'm getting failures in things like testKeyboardAnimationWillWaitUIThreadVsync which is hard to believe it could be related to this change. I'll keep trying rebasing for now.

This is failing because of changes to golden images in the bespoke platform view golden tests.

Man, looking at the goldens, most of the time this different is completely unnoticeable. It stinks to have to incur the extra performance cost because there isn't a good heuristic to determine if it is necessary or not.
