* Late filing information to a message.
* In contrast to the dc_msg_set_*() functions, this function really stores the information in the database.
*
* Sometimes, the core cannot find out the width, the height or the duration
* of an image, an audio or a video.
*
* If, in these cases, the frontend can provide the information, it can save
* them together with the message object for later usage.
*
* This function should only be used if dc_msg_get_width(), dc_msg_get_height() or dc_msg_get_duration()
* do not provide the expected values.
*
* To get the stored values later, use dc_msg_get_width(), dc_msg_get_height() or dc_msg_get_duration().
*
* @memberof dc_msg_t
* @param msg The message object.
* @param width The new width to store in the message object. 0 if you do not want to change width and height.
