*
* @param {Image} originalImg - The user's photo as a JavaScript Image object.
* @param {string} fullName - The full name to display (e.g., "MARY L SAMPLE").
* @param {string} address - The full address, with newlines represented by '\n' (e.g., "1234 SAMPLE ST\nANYTOWN OK 73101").
* @param {string} dob - The date of birth in MM-DD-YYYY format.
* @param {string} licenseNumber - The driver's license number (e.g., "S12345678").
* @param {string} issueDate - The issue date in MM-DD-YYYY format.
* @param {string} expiryDate - The expiration date in MM-DD-YYYY format.
* @param {string} gender - The gender identifier (e.g., "F").
* @param {string} height - The height in ft-in format (e.g., "5-10").
* @param {string} eyes - The eye color abbreviation (e.g., "BRO").
* @param {string} organDonor - Organ donor status. "Yes" or "Y" will display the symbol.
* @param {string} signatureText - The text to use for generating the signature.
* @returns {Promise<HTMLCanvasElement>} A canvas element containing the generated driver's license mockup.
