JS image decode
Background
It is currently cumbersome to go from an encoded Blob or ArrayBuffer of image bytes to an ImageData (Uint8ClampedArray) for further image processing. See current/index.html for an example where a user can select an image from disk and have JS turn it into a grayscale version (no backend server).
Proposal
We propose... See proposed/index.html for an API that makes this much cleaner. It uses the CanvasKit WASM library under the hood to provide functionality, but the intent is for Web Browsers to support this natively.
