* how these flags are being used:
 *  - ANY, DISPLAY, and PRINT are the normal rendering intents, note the
 *    `PDFPageProxy.{render, getOperatorList, getAnnotations}`-methods.
 *  - 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
 *    and their `annotationMode`-option.
 *  - OPLIST is used with the `PDFPageProxy.getOperatorList`-method, note the
 *    `OperatorList`-constructor (on the worker-thread).
