- 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.
- Add lock toggle
- Tweak lock and enabled styles
- Update entity list action bar w/ delete & delete all
- Move add layer menu to action bar
- Adjust opacity slider style
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.
Things like `$lastCursorPos` are now created within the canvas drawing classes. Consumers in react access them via `useCanvasManager`.
For example:
```tsx
const canvasManager = useCanvasManager();
const lastCursorPos = useStore(canvasManager.stateApi.$lastCursorPos);
```
