/**
 * This typedef represents an opaque handle assigned by the browser to the
 * resource. The handle is guaranteed never to be 0 for a valid resource, so a
 * 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 <code>AddRefResource()</code>
 * and <code>ReleaseResource()</code> in <code>ppb_core.h</code> to manage the
 * reference count of a resource. The data will be automatically destroyed when
 * the internal reference count reaches 0.
