I broke this in dfac0292f4 due to misunderstanding of what the upscale model actually was. I thought it was a main model but actually its a spandrel model.
There's a situation in which the enqueue response comes after the graph actually executes. This was unexpected when I first wrote the logic. I suppose it has to do with the async endpoint handling.
- Update canvas slice's to track the current base model architecture instead of just the optimal dimension. This lets us derive both optimal dimension _and_ grid size for the currently selected model.
- Update all bbox size utilities to use derived grid size instead of hardcoded values of 8 or 64
- Review every damned instance of the number 8 in the whole frontend and update the ones that need to use the grid size
- Update the invoke button blocking logic to check against scaled bbox size, unless scaling is disabled.
- Update the invoke button blocking to say if it's width or height that is invalid and if its bbox or scaled, for both FLUX and the T2I adapter constraints
- Use consistent logic for all model type handlers
- Fix bug where we could select invalid upscaling models (not sure how this hadn't caused problems...)
- Add logging for each action
- Only reset models when there is a change to be made - skip dispatching actions when there would be no change made to state
Previously the setting was `showOnlyRasterLayersWhileStaging`. This has been renamed to `isolatedStagingPreview`. Works the same.
Also added `isolatedFilteringPreview` an `isolatedTransformingPreview`. These work the same way, but they isolate the current selected layer. There are toggles in the canvas settings popover _and_ the filter/transform popups (same setting).
We need to ensure the getQueueCountsByDestination query is sync'd, invalidating its tags as queue items complete. Unfortunately it's 2 extra network requests per queue item.
Also clean up some jank w/ the handling of accepting staging images - there was this no-op action & a listener for it... should just be a simple callback.
