Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1379 X-link: https://github.com/facebook/react-native/pull/39403 Right now we have a `pointScaleFactor` per-node, but only ever read the one off the root node. In most cases where config is global, these will be the same, but it is possible for these to differ. This... doesn't make much sense from an API perspective, and there are edge cases where we may want to allow laying out a subtree with a different DPI then the rest of the tree (though I think there might be other solutions to that). We should rethink some of what is currently on config being allowed per-node (do we really need each node to be able to have a separate logger?), but this makes the model consistent in the meantime. This change is breaking to any users relying on setting `pointScaleFactor` on the config of the root node, but not other nodes.
