Hi!
This is great work!
There's work in the Chromium port going on that has a similar goal as your
parallel image decoding effort. There are some parts that we overlap that I
think should be discussed to avoid clashes.
Here's some background information of what we're doing. In Chromium port

Hi everyone!
A few weeks ago some folks from company100.net have started a thread of
multithreaded (parallel) image decoding in WebKit. We have worked together
since then to get a better idea how to complete this feature. I would like
to report on the progress and our plan.

I agree we should have a separate row-based downscaling phase.
JPEGImageDecoder.cpp already supports downscaling with a given width and
height, but it's using point sampling which has poor quality. It would be
nice to have a callback based downscaling API that we can implement better
algorithms.
That's a good point. I'm not sure but a safe bet would be after RenderView
is layout'ed then iterate through images to start decoding.
The same thing would be needed for scrolling too, as page scrolls need to
iterate images in the viewport.
