The patch is a port of a similar Blink patch: https://codereview.chromium.org/25105004

According to the spec "When an img element has a current pixel density that is not 1.0, the element's image data must be treated as if its resolution, in device pixels per CSS pixels, was the current pixel density."

Some small things to fix up.

What?

I think this should go back to being if (CachedImage* cachedImage = ....)

Nit, missing .

I'm confused here - I don't see the actual test, just the expected results. And it's a DRT dump, so probably should be in platform.

Why are you skipping these? Your changelog doesn't mention it. Why skip tests that you're adding in this patch? It might be better to check in failing results.

Go for it, once you've fixed the failure. Thanks Yoav!

Maybe we should mark these as failing rather than skipping. That way we won't forget them when we fix the other bugs.
