title: How to create a new ImageData object independently?
body: <p>I want to create a new ImageData object in code. If I have a <code>Uint8ClampedArray</code> out of which I want to make an image object, what is the best way to do it?</p>
  
  <p>I guess I could make a new canvas element, extract its ImageData and overwrite its data attribute, but that seems like a wrong approach.</p>
  
  <p>It would be great if I could use the ImageData constructor directly, but I can't figure out how to.</p>
