I now see that you just moved this, but still:

Is this "g" prefix something we use in WebKit? I don’t think it is. I would have used no prefix at all, but others, I guess, use an "s_" prefix. Even better, just put these constants into the header file inside the static function member return statements and don’t bother with data members.

There is no reason to use traverseNextWithWrap(false) instead of traverseNext(). This seems to be a mistake in Page::setMinimumTimerInterval and Page::setTimerThrottlingEnabled that we should fix and not repeat.

I don’t understand what the comment “per-page” means. Aren’t all settings on Settings equally per-page or not-per-page?

It’s more logical to list the default alignment interval first and then the hidden page alignment interval.
