Bug 120119 – Add some operator overloads to VisiblePosition

• Component: WebCore Misc.
• Status: RESOLVED INVALID

[Roger Fong]

Having these here does no harm and they're quite useful for comparing VisiblePositions.
I need them for https://bugs.webkit.org/show_bug.cgi?id=119829

I don't think this comparison operator makes sense.  Just because nodes aren't same doesn't mean they aren't comparable.

If anything, we should be calling comparePositions instead. r-.

didn't realize that method existed...will use that instead.
