Focus-appearance flipped version

Hi Wilco (and list),

In the survey that we didn't have time for today on focus-appearance, you mentioned that you didn't think we'd resolved this previous comment:
"I think the rewording still does not make it clear that not every single pixel in the focus indicator needs to have a contrast ratio of 3:1. I think this SC needs to be flipped around. The steps to go through to figure out conformance here is that you first count how many pixels in the focus state have a contrast ratio of 3:1 the unfocused state, and only than check do you check whether or not there is enough of them."

We had discussed this previously:

As I mentioned then, I'd looked at how that would work, but it is a chicken and egg situation, and it could undermines the 'adjacent' contrast bullet. I took another stab today, and still couldn't see how to make that work.

However, I did try adjusting it so the minimum focus indicator definition becomes the lynchpin of that (something DavidM suggested I think):

I'm not entirely happy with that, the unobscured bit now dangles, and the min-focus indicator definition may need work.

I wanted to try and address the comment, but I'm not convinced  it helps.

Kind regards,

-Alastair
