They're *clearly* two different things. It being a different things doesn't
imply it "having nothing to do with what we're talking about".
And you know why: specifically, look above and you'll see me say "Listen,
will you concede [...] at least [...]".

Ok, you're really being captious on purpose now. Sorry, I just can't avoid
thinking that.
I very, very clearly stated that I had given up trying to convince you of
the whole thing we've been talking about; now, I simply said: look, since
we can't agree about this, will we at least agree about something narrower
but related (i.e. the orange mask stuff) that doesn't features complicated
issues like the "preview keyhole" and the likes?
Really, I have only one thing left to say now: "bah".
