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.
Two main changes:
- Add `runGraphAndReturnImageOutput` to `CanvasStateApiModule`. This method is a safe and convenient abstraction to execute a graph and retrieve the image output of one of its nodes. It supports cancellation (via an AbortSignal) and timeout.
- Update filters to build whole graphs, as opposed to nodes.
These changes allow:
- Filter execution is resilient, with all error cases handled (afaik)
- `CanvasEntityFilterer` class is much simpler
- Stuck or long-running filters may be canceled
- Filters may be arbitrarily complex - so long as there is one node that outputs an image, the filter will just work
- Rename util to `getImageDTOSafe`
- Update API to accept the same options as RTKQ's `initiate`
- Add `getImageDTO`; while `getImageDTOSafe` returns null if the image is not found, the new util throws
- Update usage of `getImageDTOSafe`
- Allow `uploadImage` util to accept `metadata` to embed in the image
- Update compositor to support `metadata` field when uploading rasterized composite layer
- Add async zod refiner to `zImageWithDims` which fetches the image as part of validation
- Add `zServerValidatedModelIdentifierField`, a zod-refined version of `zModelIdentifierField` which fetches the model as part of validation
- Add `zCanvasMetadata` zod schema, which contains only canvas entities - no bbox, and no `isHidden` flags
Also update the verbiage for the alerts:
- "Sending to Canvas" -> "Staging Generations on Canvas"
- "Sending to Gallery" -> "Sending Generations to Gallery"
- Add buttons to zoom in/out
- Update hotkeys for fit & 100% to match affinity (e.g. ctrl+0, ctrl+1)
- Add hotkeys for 200%, 400%, 800%
- Update tooltips
This mirrors affinity/photoshop's default `d` hotkey, which sets the fg/bg to white/black. We don't have a concept of "background color", and white is more useful for control images, so it sets to white.
- Rework hotkey data to include the keys for each hotkey action.
- Add wrapper for `useHotkeys` that accepts a hotkey category and id. Automatically selects the key from the hotkey data.
- Add handling for macOS (cmd vs ctrl, option vs alt).
- Redo all hotkey descriptions, deleting nonexistant ones.
- Some `esc` hotkeys that just close whatever you are currently in are omitted due to their relative simplicity and intuitiveness.
