The class now has two separate methods for setting a duration or a point value. They MUST be used appropriately, because their behavior is different. When ::set_duration() is used in timecode mode, an extent (inclusive-end length) is shown rather than a length. Some objects, such as the TimeInfoBox, now deliberately shown an inclusive end for their "end" clock, but this not universally followed, pending more feedback from users and investigating of conventions in other DAWs.
