/**
 * \short Annotation class holding properties shared by all annotations.
 *
 * An Annotation is an object (text note, highlight, sound, popup window, ..)
 * contained by a Page in the document.
 *
 * \warning Different Annotation objects might point to the same annotation.
 *
 * \section annotCreation How to add annotations
 *
 * Create an Annotation object of the desired subclass (for example
 * TextAnnotation) and set its properties:
 * @code
 * Poppler::TextAnnotation* myann = new Poppler::TextAnnotation(Poppler::TextAnnotation::InPlace);
 * myann->setBoundary(QRectF(0.1, 0.1, 0.2, 0.2)); // normalized coordinates: (0,0) is top-left, (1,1) is bottom-right
 * myann->setContents("Hello, world!");
 * @endcode
 * \note Always set a boundary rectangle, or nothing will be shown!
 *
 * Obtain a pointer to the Page where you want to add the annotation (refer to
 * \ref req for instructions) and add the annotation:
 * @code
 * Poppler::Page* mypage = ...;
 * mypage->addAnnotation(myann);
 * @endcode
 *
 * You can keep on editing the annotation after it has been added to the page:
 * @code
 * myann->setContents("World, hello!"); // Let's change text...
 * myann->setAuthor("Your name here");  // ...and set an author too
 * @endcode
 *
 * When you're done with editing the annotation, you must destroy the Annotation
 * object:
 * @code
 * delete myann;
 * @endcode
 *
 * Use the PDFConverter class to save the modified document.
 *
 * \section annotFixedRotation FixedRotation flag specifics
 *
 * According to the PDF specification, annotations whose
 * Annotation::FixedRotation flag is set must always be shown in their original
 * orientation, no matter what the current rendering rotation or the page's
 * Page::orientation() values are. In comparison with regular annotations, such
 * annotations should therefore be transformed by an extra rotation at rendering
 * time to "undo" such context-related rotations, which is equal to
 * <code>-(rendering_rotation + page_orientation)</code>. The rotation pivot
 * is the top-left corner of the boundary rectangle.
 *
 * In practice, %Poppler's \ref Page::renderToImage only "unrotates" the
 * page orientation, and does <b>not</b> unrotate the rendering rotation.
 * This ensures consistent renderings at different Page::Rotation values:
 * annotations are always positioned as if they were being positioned at the
 * default page orientation.
 *
 * Just like regular annotations, %Poppler Qt6 exposes normalized coordinates
 * relative to the page's default orientation. However, behind the scenes, the
 * coordinate system is different and %Poppler transparently transforms each
 * shape. If you never call either Annotation::setFlags or
 * Annotation::setBoundary, you don't need to worry about this; but if you do
 * call them, then you need to adhere to the following rules:
 *  - Whenever you toggle the Annotation::FixedRotation flag, you <b>must</b>
 *    set again the boundary rectangle first, and then you <b>must</b> set
 *    again any other geometry-related property.
 *  - Whenever you modify the boundary rectangle of an annotation whose
 *    Annotation::FixedRotation flag is set, you <b>must</b> set again any other
 *    geometry-related property.
 *
 * These two rules are necessary to make %Poppler's transparent coordinate
 * conversion work properly.
