Detailed Description

Utility class used to notify observers how a panorama has scrolled. Panoramas notify interested observers when a change in perspective occurrs. In order to support live scrolling and hardware scrolling, observers need more information than just a pointer to the panorama. A pointer to the following structure is placed in the changedBy parameter of update when observers are notified of changes.

Currently there is a bug when InDesign broadcasts kScrollToMessage, the offset value is the negative of what it should be so current observers need to take this into account.
