Use a WebWorker for fill mode #26

Need to test this, but the following approach might really enhance UX of the fill mode.

  1. initiate filling, show loading cursor, block drawing until step 5
  2. send the ImageData to a WW
  3. let the WW fill the appropriate pixels while the user revels in their unblocked UI
  4. WW sends back ImageData, we use drawImage to render it as it's a lot faster.
  5. stop filling, unblock drawing, have fun

I'd say this should be pretty high priority as it's a major UX improvement especially for using atrament canvas in a larger app with lots of other UI.
