Extend ImageLoader functionality to be able to work with image sources containing headers We preserve the existing strategy that works with image.src for cases where source is just an uri with no headers When sources contain headers we make a fetch request and then render a local url for the downloaded blob (URL.createObjectURL) Fix #1019 Fix #2268 Close #2442
