 *  - ANNOTATIONS_FORMS, ANNOTATIONS_STORAGE, ANNOTATIONS_DISABLE control which
 *    annotations are rendered onto the canvas (i.e. by being included in the
 *    operatorList), note the `PDFPageProxy.{render, getOperatorList}`-methods

 *  - OPLIST is used with the `PDFPageProxy.getOperatorList`-method, note the
