3 months ago history snapshots should be stored as a subset of AppState
- color ramps, selected color, layers, currentLayer, canvas size, selection state
actions for undo/redo include
- changes to layer and selection (painting, selection changes, transformations)
- canvas transformations
- any changes to color ramps
The History Stack should contain named states to go back to via undo/redo https://pub.dev/packages/undo
