I remember that we had considered the alternative of merging this into PPB_Var.
It seems more consistent with the current API: PPB_Var contains conversion
methods to/from other types.
Have we decided *not* to do that? (I don't remember. :))

My recollection is that we had decided to merge it in to PPB_Var.

(I think I had voted for PPB_VarResource initially, but you all talked me in to
PPB_Var, and I'm still fine with that :-) )

Done.

   /**
    * Converts a resource-type var to a <code>PP_Resource</code>.
    *
    * @param[in] var A <code>PP_Var</code> struct containing a resource-type var.
    *
    * @return A <code>PP_Resource</code> retrieved from the var, or 0 if the var
    * is not a resource. The reference count of the resource is incremented on
    * behalf of the caller.
    */
   PP_Resource VarToResource([in] PP_Var var);
 
   /**
    * Creates a new <code>PP_Var</code> from a given resource.
    *
    * @param[in] resource A <code>PP_Resource</code> to be wrapped in a var.

    * <code>PP_VARTYPE_RESOURCE</code>. The reference count of the var is set to

   PP_Var VarFromResource([in] PP_Resource resource);
