Looks good overall with a couple of minor issues that can be fixed upon landing.

> +        for (int y = 0; y < height; y++) {
Apparently WebKit style prefers preincrement (++y rather than y++). Note that changing this wouldn't change the functionality of the loop.

> WebCore/platform/graphics/skia/PlatformContextSkia.cpp:734
>              // Start compositing into the empty canvas.
This comment should probably change.

> WebCore/platform/graphics/skia/PlatformContextSkia.cpp:818
> +    SkRect bounds = {m_softwareDirtyRect.x(), m_softwareDirtyRect.y(), m_softwareDirtyRect.right(), m_softwareDirtyRect.bottom()};
There's a casting operator SkRect() on FloatRect when compiled against Skia.
