* @brief Prepare for the next frame/page in the image file.
* @return A time in milliseconds to keep displaying the current frame before trying to draw
* the next frame. Watch out for the special values TIME_IMMEDIATE and TIME_INFINITE.
*
* @param[in] gh The widget handle (must be an image box handle)
*
* @pre gwinImageOpenXxx() must have returned successfully.
*
* @note It will return TIME_IMMEDIATE if the first frame/page hasn't been drawn or if the next frame
* should be drawn immediately.
* @note It will return TIME_INFINITE if another image frame doesn't exist or an error has occurred.
* @note Images that support multiple pages (eg TIFF files) will return TIME_IMMEDIATE between pages
* and then TIME_INFINITE when there are no more pages.
* @note An image that displays a looped animation will never return TIME_INFINITE unless it
* gets an error.
