* Simpler image cache API for clients to use. * Significantly fewer threads. * One thread for image cache task (multiplexes commands, decoder threads and async resource requests). * 4 threads for decoder worker tasks. * Removed ReflowEvent hacks in script and layout tasks. * Image elements pass a Trusted<T> to image cache, which is used to dirty nodes via script task. Previous use of Untrusted addresses was unsafe. * Image requests such as background-image on layout / paint threads trigger repaint only rather than full reflow. * Add reflow batching for when multiple images load quickly. * Reduces the number of paints loading wikipedia from ~95 to ~35. * Reasonably simple to add proper prefetch support in a follow up PR. * Async loaded images always construct Image fragments now, instead of generic. * Image fragments support the image not being present. * Simpler implementation of synchronous image loading for reftests. * Removed image holder. * image.onload support. * image NaturalWidth and NaturalHeight support. * Updated WPT expectations.
