pub fn extract_loaded_images(main: &mut World, render: &mut World)Expand description
Extracts every (Transform, LoadedImage) entity into a paired ExtractedImage + ExtractedImageBlob
in the render world. Clones the Blob (Arc-cheap) so the renderer’s upload-cache identity is preserved across
frames.
The sidecar ExtractedImageBlob is the Node-IR-ready blob payload - see its doc-comment for the splice
path to Node::Image { blob: Some(...) }.
