Replay at an exact position

User is able to start replaying audio data from a precise point in the graph, by simply positioning the replay cursor to that position.

This is done by touching the screen at the desired position. The cursor is moved and, depending on the current replay state (playing or paused), the audio data is replayed on the call.

This positioning can be performed as many times as needed to re-listen to the same audio part of the call, as long as the audio data is still valid (see Replay more audio data).
