/**
 * Calculate the proper rect for highlight annotation serialization
 *
 * This method replicates the getRect logic from PDF.js AnnotationEditor to ensure
 * that outlines are properly serialized when saving documents. The issue was that
 * the original rect was not being calculated in the same coordinate system that
 * PDF.js uses for outline serialization.
 *
 * In PDF.js, the HighlightEditor.serialize() method calls:
 * 1. const rect = this.getRect(0, 0) - to get the rect in page coordinates
 * 2. outlines: this.#serializeOutlines(rect) - to serialize outlines using that rect
 *
 * The #serializeOutlines method then calls:
 * return this.#highlightOutlines.serialize(rect, this.#getRotation())
 *
 * This ensures that the outlines are properly transformed from normalized coordinates
 * (0-1 range) to actual page coordinates, taking into account page translation and rotation.
 *
 * Since we use dontFlip: true in getViewport, the coordinates are already in PDF
 * coordinate system (Y=0 at bottom), so we don't need to flip Y coordinates again.
 *
 * @param {number[]} quadPoints - The quad points of the annotation in page coordinates
 * @param {Object} pageDimensions - Page dimensions and translation from viewport.rawDims
 * @param {number} rotation - Page rotation in degrees (0, 90, 180, 270)
 * @param {boolean} isDontFlip - Whether the viewport was created with dontFlip: true (default: true)
 * @returns {number[]} The calculated rect [x1, y1, x2, y2] in page coordinates
