- Canvas generation mode is replace with a boolean `sendToCanvas` flag. When off, images generated on the canvas go to the gallery. When on, they get added to the staging area.
- When an image result is received, if its destination is the canvas, staging is automatically started.
- Updated queue list to show the destination column.
- Added `IconSwitch` component to represent binary choices, used for the new `sendToCanvas` flag and image viewer toggle.
- Remove the queue actions menu in `QueueControls`. Move the queue count badge to the cancel button.
- Redo layout of `QueueControls` to prevent duplicate queue count badges.
- Fix issue where gallery and options panels could show thru transparent regions of queue tab.
- Disable panel hotkeys when on mm/queue tabs.
Previously this badge, floating over the queue menu button next to the invoke button, was rendered within the existing layout. When I initially positioned it, the app layout interfered - it would extend into an area reserved for a flex gap, which cut off the badge.
As a (bad) workaround, I had shifted the whole app down a few pixels to make room for it. What I should have done is what I've done in this commit - render the badge in a portal to take it out of the layout so we don't need that extra vertical padding.
Sleekified some styling a bit too.
I learned that the inline selector syntax recreates the selector function on every render:
```ts
const val = useAppSelector((s) => s.slice.val)
```
Not good! Better is to create a selector outside the function and use it. Doing that for all selectors now, most of the way through now. Feels snappier.
Previously, canvas actions specific to an entity type only needed the id of that entity type. This allowed you to pass in the id of an entity of the wrong type.
All actions for a specific entity now take a full entity identifier, and the entity identifier type can be narrowed.
`selectEntity` and `selectEntityOrThrow` now need a full entity identifier, and narrow their return values to a specific entity type _if_ the entity identifier is narrowed.
The types for canvas entities are updated with optional type parameters for this purpose.
All reducers, actions and components have been updated.
Download events and invocation status events (including progress images) are very frequent. There's no real need for these to pass through redux. Handling them outside redux is a significant performance win - far fewer store subscription calls, far fewer trips through middleware.
All event handling is moved outside middleware. Cleanup of unused actions and listeners to follow.
