It feels like this ifdef is more appropriate in the platform-y Chrome code instead of here.

Can this just be a UIView? It’s kind of weird to spread knowledge of WKContentView, and I don’t think it’s important in this case.

This looks like a leak. But it’s not, because you release them in dealloc. But the array was retaining them, so the extra ref was for naught. If you did things the WebKit way this would be

auto row = adoptNS([colorButtonsRow copy]);
[colorButtons addObject:row.get()];

and then nothing in dealloc.

> +    [_colorMatrix release];

Why not RetainPtr instead of this?

Why are you doing all this yourself? I’m sure we have UIColor->Color code elsewhere.

I made it a WKContentView because the view is passed through to another class which has WKContentView specific logic. If I changed it to a UIView here, I would need to cast to WKContentView later on. Do you prefer casting or keeping the definition as-is?

No, no, leave it as is. I didn't see the WKContentView specific bit.

In retrospect, there's not even a real reason for this copy.

This #endif got left behind. :) It seems to be what's rendering text diffs invalid on WinCairo right now:

Sorry about that! I'll put up a patch to remove it.
