 *   decisions are either webkit_policy_decision_use() or
 *   webkit_policy_decision_ignore(). This type of policy decision is always

 *   and stylesheets as well as main documents. Appropriate policy responses to
 *   this decision are webkit_policy_decision_use(), webkit_policy_decision_ignore(),
 *   or webkit_policy_decision_download(). This type of policy decision is always
 *   a #WebKitResponsePolicyDecision. This decision is useful for forcing
