Brew MP 1.0.2
Retrieves a transition living in the manager. This function is intended to
be used as a batch grab of all transitions living in the manager at that
point in time. The index of a transition may change from one step to another
based on the order they are in the manager queue, thus a transition should
never be paired to a specific index.
An application that wishes to modify a transition after inserting it within
a manager should not rely on this function to retrieve it, instead it should
explicitly keep a reference to that transition.
Pointer to the ITransitionMgr interface object.
