 22 *	@abstract	Declares an API that Carbon applications can use to interact with Growl.
 23 *	@discussion	GrowlApplicationBridge uses a delegate to provide information //XXX
 24 *	 to Growl (such as your application's name and what notifications it may
 25 *	 post) and to provide information to your application (such as that Growl
 26 *	 is listening for notifications or that a notification has been clicked).
 27 *
 28 *	 You can set the Growldelegate with Growl_SetDelegate and find out the
 29 *	 current delegate with Growl_GetDelegate. See struct Growl_Delegate for more
 30 *	 information about the delegate.

 36 *	@abstract Delegate to supply GrowlApplicationBridge with information and respond to events.

 39 *	 your application, it looks for it in the delegate; when Growl or the user
 40 *	 does something that you might be interested in, GrowlApplicationBridge
 41 *	 looks for a callback in the delegate and calls it if present
 42 *	 (meaning, if it is not <code>NULL</code>).
 43 *	XXX on all of that
 44 *  @field size The size of the delegate structure.
 45 * 	@field applicationName The name of your application.
 46 * 	@field registrationDictionary A dictionary describing your application and the notifications it can send out.
 47 * 	@field applicationIconData Your application's icon.
 48 * 	@field growlInstallationWindowTitle The title of the installation window.
 49 * 	@field growlInstallationInformation Text to display in the installation window.
 50 * 	@field growlUpdateWindowTitle The title of the update window.
 51 * 	@field growlUpdateInformation Text to display in the update window.
 52 * 	@field referenceCount A count of owners of the delegate.
 53 * 	@field retain Called when GrowlApplicationBridge receives this delegate.
 54 * 	@field release Called when GrowlApplicationBridge no longer needs this delegate.
 55 * 	@field growlIsReady Called when GrowlHelperApp is listening for notifications.
 56 * 	@field growlNotificationWasClicked Called when a Growl notification is clicked.
 57 *  @field growlNotificationTimedOut Called when a Growl notification timed out.
