 // This is the base class for all DOM event targets. To make your class an
 // EventTarget, follow these steps:
 // - Make your IDL interface inherit from EventTarget.
 // - Inherit from EventTargetWithInlineData (only in rare cases should you
 //   use EventTarget directly).
 // - In your class declaration, EventTargetWithInlineData must come first in
 //   the base class list. If your class is non-final, classes inheriting from
 //   your class need to come first, too.
