This code didn't actually use QMutableEventPoint::from(), so didn't run into the UB that from() depended on, but it's in the way of making QMutableEventPoint a befriendable namespace instead of a public subclass of QEventPoint. Replaced the QMutableEventPoint ctor that takes a timestamp, and therefore isn't compatible with the ctors on QEventPoint, with a static function that returns QEventPoint instead. Port QList initialization to braced-initialization as a drive-by.
