The in-point of a clip is kept in sync with its core children, unless they have no has-internal-source. The max-duration is defined as the minimum max-duration amongst the clip's core children. If it is set to a new value, this sets the max-duration of its core children to the same value if they have has-internal-source set as TRUE. Non-core children (such as effects on a source clip) do not influence these values. As part of this, we no longer track in-point in GESContainer. Unlike start and duration, the in-point of a timeline element does not refer to its extent in the timeline. As such, it has little meaning for most collections of timeline-elements, in particular GESGroups. As such, there is no generic way to relate the in-point of a container to its children.
