* This typdef represents an opaque handle assigned by the browser to the

* module can initialize it to 0 to indicate a "NULL handle." Some interfaces
* may return a NULL resource to indicate failure.
*
* While a Var represents something callable to JS or from the module to
* the DOM, a resource has no meaning or visibility outside of the module
* interface.
*
* Resources are reference counted. Use AddRefResource and ReleaseResource in
* ppb_core.h to manage the reference count of a resource. The data will be
* automatically destroyed when the internal reference count reaches 0.
