Add a heuristic to determine the “primary” snapshotted plugin

[Tim Horton]

So it could be styled differently, etc. via a UA stylesheet.

Putting it in WK2 because that’ll keep it out of the way for most people... while a heuristic like this doesn’t really belong in WebKit at all - it’s going to require a good bit of effort to make it possible to put it in the client. We plan to eventually expose enough knowledge to do that, but not yet.

Can we use a different #define that PLATFORM(MAC) for this, at the very least to be more descriptive.

Yeah, I was considering that. Currently trying to consolidate all of the #ifs in one file so that that becomes less touch-Platform.h and more add-something-to-the-top-of-WebPage.

I’m having a hard time telling if that’s a legitimate thing to do. People seem to be using WTF_USE_ for that, which I think is wrong, it should be WTF_ENABLE_, and it’s not done very often. I’ll move it to Platform.h/wherever if someone complains.

You can swap these two statements.
