When a layer is initialized, we do not yet know its bbox, so we cannot fit the stage view to the layer. We have to wait for the bbox calculation to finish. Previously, we had no way to wait unti lthat bbox calculation was complete to take an action.
For example, this means we could not fit the layers to the stage immediately after creating a new layer, bc we don't know the dimensions of the layer yet.
This callback lets us do that. When creating a new canvas from an image, we now...
- Register a bbox update callback to fit the layers to stage
- Layer is created
- Canvas initializes the layer's entity adapter module (layer's width and height are set to zero at this point)
- Canvas calculates the bbox
- Bbox is updated (width and height are now correct)
- Callback is ran, fitting layer to stage
A redux selector is used to get the "default" IP Adapter. The selector uses the model list query result to select an IP Adapter model to be preset by default.
The selector is memoized, so if we mutate the returned default IP Adapter state, it mutates the result of the selector for all consumers.
For example, the `image` property of the default IP Adapter selector result is `null`. When we set the `image` property of the selector result while creating an IP Adapter, this does not trigger the selector to recompute its result. We end up setting the image for the selector result directly, and all other consumers now have that same image set.
Solution - we need to clone the selector result everywhere it is used. This was missed in a few spots, causing the issue.
- Add special handling for `ImageBatchInvocation`
- Add input component for image collections, supporting multi-image upload and dnd
- Minor rework of some hooks for accessing node data
We don't need a "dnd" image system. We need a "image action" system. We need to execute specific flows with images from various "origins":
- internal dnd e.g. from gallery
- external dnd e.g. user drags an image file into the browser
- direct file upload e.g. user clicks an upload button
- some other internal app button e.g. a context menu
The actions are now generalized to better support these various use-cases.
