 /**
  * A resource is data associated with the Pepper plugin interface. While a
  * Var represents something callable to JS or from the plugin to the DOM, a
  * resource has no meaning or visibility outside of the plugin interface.
  *
  * Resources are reference counted. Use AddRefResource and ReleaseResource to
  * manage your reference count of a resource. The data will be automatically
  * destroyed when the internal reference count reaches 0.
  *
  * Value is an opaque handle assigned by the browser to the resource. It is
  * guaranteed never to be 0 for a valid resource, so a plugin can initialize
  * it to 0 to indicate a "NULL handle." Some interfaces may return a NULL
  * resource to indicate failure.
