Decode images asynchronously

[nhunzaker]

Looks like you can load/decode images off the main-thread with:

fetch(imageSrc)
  .then(response => response.blob())
  .then(blob => createImageBitmap(blob))
  .then(image => ...)

I wonder if there's an advantage to using this on the gallery.

Did some testing. This isn't faster and adds complexity to loading states.
