Some thoughts and questions after a brief overview:
  - It is a serious limitation that we can only paint the image when it has been fully downloaded. We should discuss whether it is acceptable in a user experience point of view.
  - This approach needs to be generalized across ports. I guess every port has a thread-safe image format so it should be possible.
  - Do you think Qt5 has a way to make using QImage not so slow?
  - Do you think it would be possible to still use QPixmap for smaller images that are decoded on the main thread and QImage for the big ones?
