The only pydantic usage was to convert strings to `Version` objects. The reason to do this conversion was to allow the register decorator to accept strings. MigrationEntry is only created inside this class, so we can just create versions from each migration when instantiating MigrationEntry instead.
Also, pydantic doesn't provide runtime time checking for arbitrary classes like Version, so we don't get any real benefit.
- Shift+C: Reset selected layer mask (same as canvas)
- Shift+D: Delete selected layer (cannot be Del, that deletes an image in gallery)
- Shift+A: Add layer (cannot be Ctrl+Shift+N, that opens a new window)
- Ctrl/Cmd+Wheel: Brush size (same as canvas)
Trying a lot of different things as I iterated, so this is smooshed into one big commit... too hard to split it now.
- Iterated on IP adapter handling and UI. Unfortunately there is an bug related to undo/redo. The IP adapter state is split across the `controlAdapters` slice and the `regionalPrompts` slice, but only the `regionalPrompts` slice supports undo/redo. If you delete the IP adapter and then undo/redo to a history state where it existed, you'll get an error. The fix is likely to merge the slices... Maybe there's a workaround.
- Iterated on UI. I think the layers are OK now.
- Removed ability to disable RP globally for now. It's enabled if you have enabled RP layers.
- Many minor tweaks and fixes.
- Keep track of whether the bbox needs to be recalculated (e.g. had lines/points added)
- Keep track of whether the bbox has eraser strokes - if yes, we need to do the full pixel-perfect bbox calculation, otherwise we can use the faster getClientRect
- Use comparison rather than Math.min/max in bbox calculation (slightly faster)
- Return `null` if no pixel data at all in bbox
