issue: https://github.com/flutter/flutter/issues/149652 doc: (currently google only) https://docs.google.com/document/d/1Rulw_noQi0G8Glb47vk17uBbb6sySDxlQe-l-0kHn14/edit?tab=t.0 This increases the RMSE value in the test in https://github.com/flutter/flutter/pull/161445 by a slight amount. I do believe this reduces the time where we get non uniform scalars and protects the integrity of relative spacing, thus being more what we expect. There is still a bug that has to do with pixel alignment that does give the illusion of stretching and shrinking though because of hard/soft lines. ## Before https://github.com/user-attachments/assets/e9b80b70-0961-4e02-9053-84d4457348e5 ## After https://github.com/user-attachments/assets/2494a2b1-497d-4a2b-afd7-23064acba293 ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
