ickshonpe e0a94abf1c Replace the local text queues in the text systems with flags stored in a component (#8549) ... # Objective `text_system` and `measure_text_system` both keep local queues to keep track of text node entities that need recomputations/remeasurement, which scales very badly with large numbers of text entities (O(n^2)) and makes the code quite difficult to understand. Also `text_system` filters for `Changed<Text>`, this isn't something that it should do. When a text node entity fails to be processed by `measure_text_system` because a font can't be found, the text node will still be added to `text_system`'s local queue for recomputation. `Text` should only ever be queued by `text_system` when a text node's geometry is modified or a new measure is added. ## Solution Remove the local text queues and use a component `TextFlags` to schedule remeasurements and recomputations. ## Changelog * Created a component `TextFlags` with fields `remeasure` and `recompute`, which can be used to schedule a text `remeasure` or `recomputation` respectively and added it to `TextBundle`. * Removed the local text queues from `measure_text_system` and `text_system` and instead use the `TextFlags` component to schedule remeasurements and recomputations. ## Migration Guide The component `TextFlags` has been added to `TextBundle`.		2023-05-08 13:57:52 +00:00
