Note that this patch is much simpler than it looks. It does the following things:

1. Undo the forking of the function code done in the patch linked in the changelog.
2. Just add the else block that contains the comment "            // Pattern: a b c c b a"

This probably needs new baselines too (i.e. this isn't the final patch, but the code should be final); I'll look into that tomorrow. See http://crbug.com/156022 for where the color values come from.

Fix the ChangeLog, satisfy the bots, the rest is at your discretion.

Maybe this could be ASSERT(deviceScaleFactor == 1 || deviceScaleFactor == 2) (see below).

> Source/WebCore/platform/graphics/skia/GraphicsContextSkia.cpp:640
> +        } else {

Maybe:

} else if (deviceScaleFactor == 2) {
 ... 
} else {
  ASSERT_NOT_REACHED();
}

That way, if we ever try to support some future DPI, we can find the problems quickly.

Nit:  this looks like

a b c c b a
d e f f e d
g h j j h g
g h j j h g
d e f f e d
a b c c b a

to me.

Done.

> satisfy the bots

I think the style bot is wrong here; the pixels would look strange with a 4 indent (not aligned with the previous line)

Done. (also in the non-mac code)

No, it's not x-symmetrical.

Yeah, I misunderstood.  Sorry for the noise.

We agreed style-bot can be ignored.  Ignore other bots at your peril.  :)  r=me
