Summary: X-link: https://github.com/facebook/react-native/pull/41390 Pull Request resolved: https://github.com/facebook/yoga/pull/1460 Yoga passes `MeasureMode`/`YGMeasureMode` to express constraints in how a box should be measured, given definite or indefinite available space. This is modeled after Android [MeasureSpec](https://developer.android.com/reference/android/view/View.MeasureSpec), with a table above `calculateLayoutImpl()` explaining the CSS terms they map to. This can be confusing when flipping between the spec, and code. This switches internal usages to the CSS terms, but leaves around `YGMeasureMode` since it is the public API passed to measure functions.
