TBH not sure exactly why this broke. Fixed by rollback back the use of a render prop in favor of global state. Also revised the API of `useBoolean` and `buildUseBoolean`.
- 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.
The frontend needs to know where queue items came from (i.e. which tab), and where results are going to (i.e. send images to gallery or canvas). The `origin` column is not quite enough to represent this cleanly.
A `destination` column provides the frontend what it needs to handle incoming generations.
This hook forcibly updates _all_ portals with `data-hidden=true` when the modal opens - then reverts it when the modal closes. It's intended to help screen readers. Unfortunately, this absolutely tanks performance because we have many portals. React needs to do alot of layout calculations (not re-renders).
IMO this behaviour is a bug in chakra. The modals which generated the portals are hidden by default, so this data attr should really be set by default. Dunno why it isn't.
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.
