Occurs when the user selects the menu or toolbar "Annotations - Revert Annotations"
command.

Public Event OnAnnotationsRevertStart()

The user has requested that all annotations for the image be reverted back to the original,
which will cause Prizm Viewer to save the original annotations back to the server.  When the
user clicks on the menu or toolbar button "Annotations - Revert Annotations", it will first
generate the "OnAnnotationsRevertStart" event, then generate the
"OnAnnotationsRevertFinish" event.
