Description

This is returned by plug-ins' mainEntry function to indicate that they did not trap the action passed and that the default operation should occur. It does not imply failure.

A subtle but specific use of this is made by plug-in interacts GUIs. If they return this value from any event actions (eg: kOfxInteractActionPenDown ), then the host is free to pass the event on to another GUI element in the interact window.
