* Closes #4534 This PR: - Introduces `Ui::stack()`, which returns the `UiStack` structure providing information on the current `Ui` hierarchy. - **BREAKING**: `Ui::new()` now takes a `UiStackInfo` argument, which is used to populate some of this `Ui`'s `UiStack`'s fields. - **BREAKING**: `Ui::child_ui()` and `Ui::child_ui_with_id_source()` now take an `Option<UiStackInfo>` argument, which is used to populate some of the children `Ui`'s `UiStack`'s fields. - New `Area::kind()` builder function, to set the `UiStackKind` value of the `Area`'s `Ui`. - Adds a (minimalistic) demo to egui demo (in the "Misc Demos" window). - Adds a more thorough `test_ui_stack` test/playground demo. TODO: - [x] benchmarks - [x] add example to demo Future work: - Add `UiStackKind` and related support for more container (e.g. `CollapsingHeader`, etc.) - Add a tag/property system that would allow adding arbitrary data to a stack node. This data could then be queried by nested `Ui`s. Probably needed for #3284. - Add support to track columnar layouts. --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
