Module undoer 

An automatic undo stack fed the current state every frame.

egui’s egui::util::undoer::Undoer (© Rerun / emilk, dual-licensed MIT OR Apache-2.0), reimplemented over Duration so nothing above the backend needs a toolkit to remember where it has been. The rules are its two:

1. a state that has differed from the newest point and then held still for stable_time becomes a point of its own;
2. a state that never holds still becomes one every auto_save_interval anyway, so a run of changes that never settles still leaves something to take back.

How the state is changing right now: when the run of changes began, when the latest of them landed, and what it landed on.
